    YOU SHOULD READ THE FOLLOWING SUMMARY TOGETHER WITH THE MORE DETAILED
INFORMATION IN THIS PROSPECTUS, INCLUDING RISK FACTORS, REGARDING OPLINK AND THE
COMMON STOCK BEING SOLD IN THIS OFFERING.

                          OPLINK COMMUNICATIONS, INC.

    We design, manufacture and market fiber optic components and integrated
optical modules that increase the performance of optical networks. We sell our
products worldwide to communication equipment suppliers. Our top customers by
revenue for the quarter ended June 30, 2000 were, listed alphabetically: ADVA
International, Cisco Systems, Corning Incorporated, JDS Uniphase Corporation,
Lucent Technologies, LuxN and Sycamore Networks. Our broad line of products
enables the following applications within a fiber optic network:

    - WAVELENGTH EXPANSION--uses dense wavelength division multiplexing, or
      DWDM, to transmit large amounts of data through multiple wavelengths of
      light.

    - OPTICAL AMPLIFICATION--amplifies optical signals without the need to
      enhance the signals electronically.

    - WAVELENGTH PERFORMANCE MONITORING AND PROTECTION--controls the direction
      of light signals by monitoring wavelength performance within an optical
      network.

    - OPTICAL SWITCHING--redirects light signals to multiple points without
      requiring the signal to be converted into an electrical one.

    These applications address the unique requirements of all segments of
communication networks including: ultra-long haul, for cross-country
connections; long haul, for long distance connections between cities;
metropolitan, for connections within urban areas; and access, for connections to
individual businesses and homes. We work closely with our customers early in
their product development cycles to design components and integrated optical
modules that meet their particular requirements. We combine our design expertise
with our manufacturing capabilities in the United States and China to produce
high performance products in large volumes.

    Data traffic has increased rapidly over the past several years, driving the
demand for greater capacity, or bandwidth, on existing communication networks.
Limitations of these networks and recent breakthroughs in optical component
technology have led to the widespread deployment of fiber optic technology,
which is able to transport large amounts of data. These breakthroughs include
new technologies that expand the bandwidth of existing optical fiber networks
and that provide intelligence, or the ability to monitor and manage optical
signals. Fiber optic components and integrated optical modules are the core
elements of optical systems that provide these capabilities within a network. We
believe that manufacturers that are able to provide a broad line of
sophisticated and customized components and modules in large volume will be in a
strong position to grow their revenues in the fiber optic market.

    Our objective is to become a leading supplier of advanced components and
integrated optical modules for the fiber optic communications industry. Key
elements of our strategy include:

    - expanding our manufacturing capacity in both the United States and China
      as well as enhancing our manufacturing capabilities through automation;

    - building new and expanding existing customer relationships to increase
      market penetration by focusing on custom design and quality;

    - expanding and enhancing our existing line of optical components and
      integrated optical modules for all segments of the optical network;

    - continuing to develop optical products with features that allow service
      providers to manage their optical networks effectively;

    - continuing to attract talented personnel; and

    - pursuing strategic acquisitions of businesses and technologies.

                          CONCURRENT PRIVATE PLACEMENT



    In August 2000, we issued a convertible promissory note to Cisco Systems in
the principal amount of $50 million. The note payable accrues interest at a rate
of 8% per annum. Upon the closing of this offering, the outstanding principal
amount and all accrued interest on the note will, subject to obtaining
regulatory approval, automatically convert into shares of our common stock at a
conversion price per share equal to 85% of the public offering price. Assuming a
public offering price of $11.00 and a closing date of September 30, 2000, the
note would convert into 5,386,272 shares of common stock.



    The common stock outstanding after this offering is based on shares
outstanding as of July 31, 2000 and includes 5,386,272 shares to be issued to
Cisco Systems upon the conversion of a convertible promissory note payable
contemporaneously with this offering, and excludes:


    - 22,363,744 shares issuable upon exercise of outstanding options as of
      July 31, 2000 with a weighted average exercise price of $1.1139;

    - 3,255,178 shares reserved for future issuance under our 1995 and 1998
      stock option plans as of July 31, 2000; and

    - 348,904 shares of common stock issuable upon exercise of outstanding
      warrants as of July 31, 2000 with a weighted average exercise price of
      $0.1720.

    Unless otherwise indicated, the information in this prospectus:

    - assumes no exercise of the underwriters' over-allotment option;

    - reflects, except in the consolidated financial statements and notes
      thereto, the conversion of all outstanding shares of our convertible
      preferred stock into shares of common stock upon completion of this
      offering;

    - reflects a 2-for-1 stock split of our common stock and preferred stock to
      be effected prior to the completion of this offering; and

    - assumes our reincorporation in Delaware before completion of this
      offering, and the associated changes in our charter documents.

                                  RISK FACTORS

    ANY INVESTMENT IN OUR SHARES OF OUR COMMON STOCK INVOLVES A HIGH DEGREE OF
RISK. YOU SHOULD CONSIDER CAREFULLY THE FOLLOWING INFORMATION ABOUT THESE RISKS,
TOGETHER WITH THE OTHER INFORMATION CONTAINED IN THIS PROSPECTUS, BEFORE YOU
DECIDE TO BUY OUR COMMON STOCK. IF ANY OF THE FOLLOWING RISKS ACTUALLY OCCUR,
OUR BUSINESS, RESULTS OF OPERATIONS AND FINANCIAL CONDITION WOULD LIKELY SUFFER.
IN THESE CIRCUMSTANCES, THE MARKET PRICE OF OUR COMMON STOCK COULD DECLINE, AND
YOU MAY LOSE ALL OR PART OF THE MONEY YOU PAID TO BUY OUR COMMON STOCK.

                    RISKS RELATED TO OUR FINANCIAL CONDITION

WE HAVE INCURRED SIGNIFICANT LOSSES, AND OUR FAILURE TO INCREASE OUR REVENUES
COULD PREVENT US FROM ACHIEVING PROFITABILITY.

    We have incurred significant losses since our inception in 1995 and expect
to incur losses in the future. We incurred net losses of $24.9 million for the
year ended June 30, 2000 and have not achieved profitability on a quarterly
basis. As of June 30, 2000, we had an accumulated deficit of $32.5 million. We
will need to generate significantly greater revenues while containing costs and
operating expenses to achieve profitability. Our revenues may not continue to
grow, and we may never generate sufficient revenues to achieve profitability.
Please see "Selected Consolidated Financial Data" and "Management's Discussion
and Analysis of Financial Condition and Results of Operations" for a discussion
of our financial condition.

WE DEPEND UPON A SMALL NUMBER OF CUSTOMERS FOR A SUBSTANTIAL PORTION OF OUR
REVENUES, AND ANY DECREASE IN REVENUES FROM, OR LOSS OF, THESE CUSTOMERS WITHOUT
A CORRESPONDING INCREASE IN REVENUES FROM OTHER CUSTOMERS WOULD HARM OUR
OPERATING RESULTS.

    We depend upon a small number of customers for a substantial portion of our
revenues. Our top three customers together accounted for 68.9% of our revenues
in the year ended June 30, 2000. Lucent Technologies, Sycamore Networks and JDS
Uniphase accounted for 42.6%, 15.7% and 10.6% of our revenues for the year ended
June 30, 2000. We expect that we will continue to depend upon a small number of
customers for a substantial portion of our revenues.

    Our revenues generated from these customers, individually or in the
aggregate, may not reach or exceed historic levels in any future period. For
example, we may not be the sole source of supply to our customers, and they may
choose to purchase products from other vendors. Furthermore, the businesses of
our existing customers could experience a downturn, which could result in
significantly decreased sales to these customers and harm our results of
operations. In this regard, Lucent has indicated that it may decrease and
eventually discontinue incorporating one of our products into some of its
products over the next two years. Lucent's purchases of these products in the
year ended June 30, 2000 accounted for 28.3% of our revenues. Lucent may not
introduce or sell significant quantities of other products that incorporate this
product. Loss or cancellations of orders from, or any downturn in the business
of, any of our customers could harm our revenues. Our dependence on a small
number of customers may increase if the optical components industry and our
target markets continue to consolidate.

BECAUSE WE DID NOT COMMENCE SALES OF OUR PRODUCTS UNTIL LATE 1996 AND ONLY
RECENTLY BEGAN SELLING OUR PRODUCTS IN LARGE VOLUME, WE MAY BE UNABLE TO
ACCURATELY FORECAST OUR REVENUES, AND OUR QUARTERLY REVENUES AND OPERATING
RESULTS MAY CONTINUE TO FLUCTUATE SIGNIFICANTLY FROM QUARTER TO QUARTER.

    We did not commence sales of our products until late 1996 and only recently
began selling our products in large volume. As a result, it is difficult to
forecast our revenues accurately. Moreover, our revenues, expenses and operating
results have varied significantly from quarter to quarter in the past

                                       4
<PAGE>
and may continue to fluctuate significantly in the future. The factors, many of
which are more fully discussed in other risk factors, that are likely to cause
these variations include, among others:

    - fluctuations in demand for, and sales of, our products;

    - cancellations of orders and shipment rescheduling;

    - our ability to significantly expand our manufacturing capacity at our
      facilities in San Jose, California and China;

    - the availability of raw materials used in our products and increases in
      the price of these raw materials;

    - the ability of our manufacturing operations in China to timely produce and
      deliver products and components in the quantity and of the quality we
      require;

    - our ability to achieve acceptable production yields;

    - the practice of communication equipment suppliers to sporadically place
      large orders with short lead times;

    - the mix of products and the average selling prices of the products we
      sell;

    - competitive factors, including introductions of new products and product
      enhancements by competitors, entry of new competitors into the optical
      networking components market and pricing pressures;

    - our ability to develop, introduce, manufacture and ship new and enhanced
      optical networking products in a timely manner without defects;

    - costs associated with and the outcomes of any intellectual property or
      other litigation to which we are, or may become, a party; and

    - economic conditions specific to the communications and related industries
      and the development and size of the markets for our products.

    Due to the factors noted above and other risks discussed in this section, we
believe that quarter-to-quarter comparisons of our operating results will not be
meaningful. You should not rely on our results for one quarter as any indication
of our future performance. Quarterly variations in our operations could result
in significant volatility in our stock price and the market price for our common
stock might fall below the initial public offering price. It is likely that, in
future quarters, our operating results may be below the expectations of
securities analysts or investors. If this occurs, the price of our common stock
is likely to decrease.

BECAUSE A HIGH PERCENTAGE OF OUR EXPENSES IS FIXED IN THE SHORT TERM, OUR
OPERATING RESULTS ARE LIKELY TO BE HARMED IF WE EXPERIENCE DELAYS IN GENERATING
AND RECOGNIZING REVENUES.

    A high percentage of our expenses, including those related to manufacturing,
engineering, research and development, sales and marketing and general and
administrative functions, is fixed in the short term. As a result, if we
experience delays in generating and recognizing revenues, our quarterly
operating results are likely to be harmed. As we expand our manufacturing
capacity, we will incur expenses in one quarter relating to the expansion that
may not result in off-setting revenues until a subsequent quarter. New product
introductions can also result in a mismatching of research and development
expenses and sales and marketing expenses that are incurred in one quarter with
revenues that are not recognized until a subsequent quarter when the new product
is introduced. If growth in our revenues does not exceed the increase in our
expenses, our results of operations will be harmed.

<PAGE>
                         RISKS RELATED TO OUR BUSINESS

IF WE FAIL TO RAPIDLY EXPAND OUR MANUFACTURING CAPACITY, WE MAY NOT BE ABLE TO
DELIVER SUFFICIENT QUANTITIES OF PRODUCTS TO OUR CUSTOMERS IN A TIMELY MANNER,
WHICH WOULD HARM OUR OPERATING RESULTS.

    We manufacture all of our products in our facilities in San Jose, California
and Zhuhai and Fuzhou, China and currently are expanding our manufacturing
capacity at our San Jose and Zhuhai facilities. We must devote significant
resources to expand our manufacturing capacity, and our planned expansion will
be expensive, will require management's time and may disrupt our operations.
Additional risks associated with rapidly increasing manufacturing capacity
include:

    - a lack of availability of manufacturing personnel;

    - difficulties in achieving adequate yields from new manufacturing lines;

    - inability to quickly implement an adequate set of financial controls to
      track levels of inventory;

    - our failure to acquire additional facilities in desirable locations on
      commercially reasonable terms; and

    - our inability to procure the necessary equipment.

    We are just beginning to receive orders for significant quantities of
products while simultaneously increasing our manufacturing capacity.
Communication equipment suppliers typically require that their vendors commit to
provide specified quantities of products over a given period of time. We could
be unable to pursue many large orders if we do not have sufficient manufacturing
capacity to enable us to commit to provide customers with specified quantities
of products. If we are unable to commit to deliver sufficient quantities of our
products to satisfy a customer's anticipated needs, we will lose the order and
the opportunity for significant sales to that customer for a lengthy period of
time. Furthermore, if we fail to fulfill orders to which we have committed, we
will lose revenue opportunities and our customer relationships may be harmed.

IF WE FAIL TO EFFECTIVELY MANAGE THE RAPID EXPANSION OF OUR OPERATIONS,
INCLUDING THE ANTICIPATED SIGNIFICANT INCREASE IN THE NUMBER OF OUR EMPLOYEES,
OUR OPERATING RESULTS COULD BE HARMED.


    We currently operate facilities in San Jose, California and in China. We are
continuing to expand the scope of our operations domestically and
internationally and to increase the number of our employees substantially. As of
July 31, 2000, we had a total of 648 full-time employees in San Jose and 804
full-time employees in China. We plan to hire a significant number of employees
over the next several quarters in connection with the expansion of our
manufacturing operations. The growth in employees and our operations, combined
with the challenges of expanding and managing geographically-dispersed
operations, has placed, and will continue to place, a significant strain on our
management systems and resources. We expect that we will need to continue to
improve our financial and managerial controls, reporting systems and procedures,
and will need to continue to expand, train and manage our workforce worldwide.
Any failure to effectively manage this expansion could harm our operating
results.


IF WE FAIL TO EFFECTIVELY MANAGE OUR INVENTORY LEVELS, OUR OPERATING RESULTS
COULD BE HARMED.

    Because we experience long lead times for raw materials and are often
required to purchase significant amounts of raw materials far in advance of
product shipments, we may not effectively manage our inventory levels, which
could harm our operating results. If we underestimate our requirements, we may
have inadequate inventory, which could result in delays in shipments and loss of
customers. If we purchase raw materials in anticipation of orders that do not
materialize, we will have to carry or write off excess inventory and our gross
margins will decline. Even if we receive these orders, the additional
manufacturing capacity that we add to meet the customer's requirements may be
underutilized in a subsequent quarter. We are in the early stages of
implementing automated

                                       6
<PAGE>
manufacturing management systems, and at present most of the data, including
some inventory levels, are tracked manually. The current limitations of our
manufacturing management systems increase the risk that we may fail to
effectively manage our inventory. In this regard, we experienced significant
increases in provisions for excess and obsolete inventory, which harmed our
gross margins, in the quarters ended March 31 and June 30, 2000. As we grow, we
will need to implement new systems, which we may fail to do on a timely basis.
The risks associated with managing our inventory are increased by the fact that
we ship products to our largest customer, Lucent, on a consignment basis, such
that we carry the shipped products as inventory until Lucent accepts the
products for use.

BECAUSE WE DEPEND ON THIRD PARTIES TO SUPPLY SOME OF OUR RAW MATERIALS AND
EQUIPMENT, WE MAY NOT BE ABLE TO OBTAIN SUFFICIENT QUANTITIES OF THESE MATERIALS
AND EQUIPMENT, WHICH COULD LIMIT OUR ABILITY TO FILL CUSTOMER ORDERS AND HARM
OUR OPERATING RESULTS.

    We depend on third parties to supply the raw materials and equipment we use
to manufacture our products. To be competitive, we must obtain from our
suppliers, on a timely basis, sufficient quantities of raw materials at
acceptable prices. We obtain most of our critical raw materials from a single or
limited number of suppliers and generally do not have long-term supply contracts
with them. As a result, our suppliers could terminate the supply of a particular
material at any time without penalty. Difficulties in obtaining raw materials in
the future may limit our product shipments. In this regard, we experienced
difficulties in obtaining GRIN lenses in the quarters ended March 31 and
June 30, 2000, and we continue to experience such difficulties.

    Some of our raw material suppliers are single sources, and finding
alternative sources may involve significant expense and delay, if these sources
can be found at all. For example, all of our GRIN lenses, which are incorporated
into substantially all of our products, are obtained from Nippon Sheet Glass.
Our failure to obtain these materials or other single or limited-source raw
materials could delay or reduce our product shipments, which could result in
lost orders, increase our costs, reduce our control over quality and delivery
schedules and require us to redesign our products. If a significant supplier
became unable or unwilling to continue to manufacture or ship materials in
required volumes, we would have to identify and qualify an acceptable
replacement. A material delay or reduction in shipments, any need to identify
and qualify replacement suppliers or any significant increase in our need for
raw materials that cannot be met on acceptable terms could harm our business.

    We also depend on a limited number of manufacturers and vendors that make
and sell the complex equipment we use in our manufacturing process. In periods
of high market demand, the lead times from order to delivery of this equipment
could be as long as nine months. Delays in the delivery of this equipment or
increases in the cost of this equipment could harm our operating results.

OUR MARKETS ARE HIGHLY COMPETITIVE, AND IF WE ARE UNABLE TO COMPETE SUCCESSFULLY
OUR REVENUES COULD DECLINE, WHICH WOULD HARM OUR OPERATING RESULTS.

    The market for fiber optic components is intensely competitive. We believe
that our principal competitors are the major manufacturers of optical components
and modules, including vendors selling to third parties and business divisions
within communication equipment suppliers. Our principal competitors in the
components market include Avanex Corporation, Ciena Corporation, Corning, DiCon
Fiberoptics, Furukawa Electrical, Lucent, New Focus, Nortel, Sumitomo, Tyco
Electronics and JDS Uniphase, which recently acquired E-TEK Dynamics and
announced its intended acquisition of SDL. We believe that we primarily compete
with diversified suppliers, such as Corning, JDS Uniphase, Lucent and Nortel,
for the majority of our product line and to a lesser extent with niche players
that offer more limited product lines. Competitors in any portion of our
business may also rapidly become competitors in other portions of our business.
In addition, our industry has recently experienced significant consolidation,
and we anticipate that further consolidation will occur. This consolidation has
further increased competition.

                                       7
<PAGE>
    Many of our current and potential competitors have significantly greater
financial, technical, marketing, purchasing, manufacturing and other resources
than we do. As a result, these competitors may be able to respond more quickly
to new or emerging technologies and to changes in customer requirements, to
devote greater resources to the development, promotion and sale of products, or
to deliver competitive products at lower prices.

    Several of our existing and potential customers are also current and
potential competitors of ours. JDS Uniphase, for example, generated 10.6% of our
revenues in the year ended June 30, 2000. These companies may develop or acquire
additional competitive products or technologies in the future and thereby reduce
or cease their purchases from us. In light of the consolidation in the optical
networking industry, we also believe that the size of the optical component and
module suppliers will become increasingly important to our current and potential
customers in the future. We may not be able to compete successfully with
existing or new competitors, and the competitive pressures we face may result in
lower prices for our products, loss of market share, or reduced gross margins,
any of which could harm our business.

    New technologies are emerging due to increased competition and customer
demand. The introduction of new products incorporating new technologies or the
emergence of new industry standards could make our existing products
noncompetitive. For example, new technologies are being developed in the design
of wavelength division multiplexers that compete with the thin film filters that
we incorporate in our products. These technologies include arrayed waveguide
grating, or AWG, which is being developed by Lucent and NTT, and fiber bragg
grating, or FBG, which is being developed by Ciena. If our competitors adopt new
technologies before we do, we could lose market share and our business would
suffer.

OUR WAVELENGTH EXPANSION PRODUCTS HAVE ACCOUNTED FOR THE VAST MAJORITY OF OUR
REVENUES, AND OUR REVENUES COULD BE HARMED IF THE PRICE OF OR DEMAND FOR THESE
PRODUCTS DECLINES OR IF THESE PRODUCTS FAIL TO ACHIEVE BROADER MARKET
ACCEPTANCE.

    Although we currently offer a broad spectrum of products, sales of our
wavelength expansion products accounted for the vast majority of our revenues in
the year ended June 30, 2000. These products include, among others, dense
wavelength division multiplexers, or DWDMs, and noise reduction filters. We
believe that our future growth and a significant portion of our future revenues
will depend on the commercial success of our wavelength expansion products.
Customers that have purchased wavelength expansion products may not continue to
purchase these products from us. Any decline in the price of, or demand for, our
wavelength expansion products, or their failure to achieve broader market
acceptance, could harm our revenues.

THE OPTICAL NETWORKING COMPONENT INDUSTRY IS EXPERIENCING DECLINING AVERAGE
SELLING PRICES, WHICH COULD CAUSE OUR GROSS MARGINS TO DECLINE AND HARM OUR
OPERATING RESULTS.

    The optical networking component industry is experiencing declining average
selling prices, or ASPs, as a result of increasing competition and greater unit
volumes as communication service providers continue to deploy fiber optic
networks. We anticipate that ASPs will continue to decrease in the future in
response to product introductions by competitors, price pressures from
significant customers and greater manufacturing efficiencies achieved through
increased automation in the manufacturing process. These ASP declines have
contributed and may continue to contribute to a decline in our gross margins,
which could harm our results of operations.

OUR FAILURE TO ACHIEVE ACCEPTABLE MANUFACTURING YIELDS IN A COST-EFFECTIVE
MANNER COULD DELAY PRODUCT SHIPMENTS TO OUR CUSTOMERS AND HARM OUR OPERATING
RESULTS.

    Because manufacturing our products involves complex and precise processes
and the majority of our manufacturing costs are relatively fixed, manufacturing
yields are critical to our results of

                                       8
<PAGE>
operations. Lower than expected manufacturing yields could delay product
shipments and harm our operating results. Factors that affect our manufacturing
yields include the quality of raw materials used to make our products, quality
of workmanship and our manufacturing processes. Our or our suppliers'
inadvertent use of defective materials could significantly reduce our
manufacturing yields. Furthermore, because of the large labor component in and
complexity of the manufacturing process, quality of workmanship is critical to
achieving acceptable yields. We cannot assure you that we will be able to hire
and train a sufficient number of qualified personnel to cost-effectively produce
our products with the quality and in the quantities required by our customers.
Changes in our manufacturing processes or those of our suppliers could also
impact our yields. In some cases, existing manufacturing techniques, which
involve substantial manual labor, may not allow us to cost-effectively meet our
manufacturing yield goals so that we maintain acceptable gross margins while
meeting the cost targets of our customers. We will need to develop new
manufacturing processes and techniques that will involve higher levels of
automation in order to increase our gross margins and help achieve the targeted
cost levels of our customers. We may not achieve manufacturing cost levels that
will allow us to achieve acceptable gross margins or fully satisfy customer
demands.

OUR PRODUCTS MAY HAVE DEFECTS THAT ARE NOT DETECTED UNTIL FULL DEPLOYMENT OF A
CUSTOMER'S EQUIPMENT, WHICH COULD RESULT IN A LOSS OF CUSTOMERS, DAMAGE TO OUR
REPUTATION AND SUBSTANTIAL COSTS.

    Our products are deployed in large and complex optical networks and must be
compatible with other system components. Our products can only be fully tested
for reliability when deployed in networks for long periods of time. Our
customers may discover errors, defects or incompatibilities in our products
after they have been fully deployed and operated under peak stress conditions.
Our products may also have errors, defects or incompatibilities that are not
found until after a system upgrade is installed. Errors, defects,
incompatibilities or other problems with our products could result in:

    - loss of customers;

    - loss of or delay in revenues;

    - loss of market share;

    - damage to our brand and reputation;

    - inability to attract new customers or achieve market acceptance;

    - diversion of development resources;

    - increased service and warranty costs;

    - legal actions by our customers; and

    - increased insurance costs.

    If any of these occur, our operating results could be harmed.

IF WE ARE UNABLE TO PROTECT OUR PROPRIETARY TECHNOLOGY, OUR ABILITY TO SUCCEED
WILL BE HARMED.

    Our ability to compete successfully and achieve future growth will depend,
in part, on our ability to protect our proprietary technology. We rely on a
combination of patent, copyright, trademark and trade secret laws and
restrictions on disclosure to protect our intellectual property rights. However,
the steps we have taken may not prevent the misappropriation of our intellectual
property, particularly in foreign countries, such as China, where the laws may
not protect our proprietary rights as fully as in the United States. We
currently hold 10 patents and have 22 pending patent applications in the United
States. We cannot assure you that patents will be issued from pending or future
applications or that, if patents are issued, they will not be challenged,
invalidated or circumvented. Rights granted under these patents may not provide
us with meaningful protection or any commercial advantage. If we are unable to
protect our proprietary technology, our ability to succeed will be harmed. We
may in the future initiate claims or litigation against third parties for
infringement of our proprietary rights. These claims could result in costly
litigation and the diversion of our technical and management personnel.

                                       9
<PAGE>
WE ARE CURRENTLY DEFENDANTS IN TWO PATENT DISPUTES AND MAY BE INVOLVED IN OTHER
INTELLECTUAL PROPERTY DISPUTES IN THE FUTURE, WHICH WILL DIVERT MANAGEMENT'S
ATTENTION, AND COULD CAUSE US TO INCUR SIGNIFICANT COSTS AND PREVENT US FROM
SELLING OR USING THE CHALLENGED TECHNOLOGY.

    Participants in the communications and optical components markets in which
we sell our products have experienced frequent litigation regarding patent and
other intellectual property rights. Numerous patents in these industries are
held by others, including our competitors and academic institutions. We have no
means of knowing that a patent application has been filed until the patent is
issued. Optical component suppliers may seek to gain a competitive advantage or
other third parties may seek an economic return on their intellectual property
portfolios by making infringement claims against us.

    In November 1999, E-TEK Dynamics filed a lawsuit against us in the United
States District Court for the Northern District of California alleging
infringement of E-TEK's patent relating to fiber optic couplers based on our
manufacture and sale of our DWDM products. E-TEK seeks an award for damages and
injunctive relief. Our DWDM products generated a majority of our revenues for
the year ended June 30, 2000. An adverse ruling in this matter would materially
adversely affect our financial condition. In addition, in June 2000, Chorum
Technologies, Inc. filed a lawsuit against us and our wholly-owned subsidiary,
Telelight Communications Inc., in the United States District Court for the
Northern District of Texas alleging, among other things, infringement of two
U.S. patents allegedly owned by Chorum relating to fiber optical interleaving,
based on our manufacture of and offer to sell various fiber optic interleaver
products. Chorum seeks an award for damages and injunctive relief. For
additional information concerning these matters, see "Business--Legal
Proceedings and Regulatory Matters."

    Defending these lawsuits, and any additional litigation to which we may
become a party in the future as a result of alleged infringement of others'
intellectual property, will likely be costly and time consuming and will divert
the efforts and attention of our management and technical personnel. Patent
litigation is highly complex and can extend for a protracted period of time,
which can substantially increase the cost of litigation. Accordingly, the
expenses and diversion of resources associated with either of these matters, or
any other intellectual property litigation to which we may become a party, could
seriously harm our business and financial condition. Any intellectual property
litigation also could invalidate our proprietary rights and force us to do one
or more of the following:

    - obtain from the owner of the infringed intellectual property right a
      license to sell or use the relevant technology, which license may not be
      available on reasonable terms, or at all;

    - stop selling, incorporating or using our products that use the challenged
      intellectual property;

    - pay substantial money damages; or

    - redesign the products that use the technology.

    If we are forced to take any of these actions, it could result in a
substantial reduction in our revenue and could result in losses over an extended
period of time.

IF WE ARE UNABLE TO DEVELOP NEW PRODUCTS AND PRODUCT ENHANCEMENTS THAT ACHIEVE
MARKET ACCEPTANCE, SALES OF OUR PRODUCTS COULD DECLINE, WHICH WOULD HARM OUR
OPERATING RESULTS.

    The communications industry is characterized by rapid technological change,
frequent new product introductions, changes in customer requirements and
evolving industry standards. As a result, our products could quickly become
obsolete as new technologies are introduced and incorporated into new and
improved products. Our future success depends on our ability to anticipate
market needs and to develop products that address those needs. Our failure to
predict market needs accurately or to develop new products or product
enhancements in a timely manner will harm market acceptance and sales of our
products. In this regard, we are currently developing bandwidth creation
products as well

                                       10
<PAGE>
as bandwidth management products. If the development of these products or any
other future products takes longer than we anticipate, or if we are unable to
develop and introduce these products to market, our revenues could suffer and we
may not gain market share. Even if we are able to develop and commercially
introduce these new products, the new products may not achieve widespread market
acceptance.

WE DEPEND ON THE CONTINUED GROWTH AND SUCCESS OF THE COMMUNICATIONS INDUSTRY,
WHICH IS EXPERIENCING RAPID CONSOLIDATION AND REALIGNMENT AND MAY NOT CONTINUE
TO DEMAND FIBER OPTIC PRODUCTS, THEREBY REDUCING DEMAND FOR OUR PRODUCTS AND
HARMING OUR OPERATING RESULTS.

    We depend on the continued growth and success of the communications
industry, including the continued growth of the Internet as a widely-used medium
for commerce and communication and the continuing demand for increased bandwidth
over communications networks. Trends that are currently driving growth in the
communications industry may not continue in a manner favorable to us and
technological or other developments in the communications industry may not favor
growth in the markets served by our products. Furthermore, the rate at which
communication service providers and other fiber optic network users have built
new fiber optic networks or installed new systems in their existing fiber optic
networks has fluctuated in the past and these fluctuations may continue in the
future. These fluctuations may result in reduced demand for new or upgraded
fiber optic systems that utilize our products and, therefore, may result in
reduced demand for our products.

    The communications industry is also experiencing rapid consolidation and
realignment, as industry participants seek to capitalize on the rapidly changing
competitive landscape developing around the Internet and new communications
technologies such as fiber optic and wireless communications networks. As the
communications industry consolidates and realigns to accommodate technological
and other developments, our customers may consolidate or align with other
entities in a manner that harms our business.

BECAUSE NONE OF OUR CUSTOMERS ARE OBLIGATED TO PURCHASE OUR PRODUCTS, THEY MAY
CANCEL OR DEFER THEIR PURCHASES ON SHORT NOTICE AND AT ANY TIME, WHICH COULD
HARM OUR OPERATING RESULTS.

    We do not have contracts with our customers that provide any assurance of
future sales, and sales are typically made pursuant to individual purchase
orders, often with extremely short lead times. Accordingly, our customers:

    - may stop purchasing our products at any time without penalty;

    - are free to purchase products from our competitors;

    - are not required to make minimum purchases; and

    - may cancel orders that they place with us.

    Sales to any single customer may vary significantly from quarter to quarter.
Our customers generally do not place purchase orders far in advance. In
addition, our customer purchase orders have varied significantly from quarter to
quarter. Our customers base their purchase orders on a decision to deploy their
systems in a particular geographic area and may not order additional products
until they make their next major deployment decision. This means that customers
who account for a significant portion of our revenues in one quarter may not
place any orders in the succeeding quarter, which makes it difficult to forecast
revenue in future periods. Moreover, our expense levels are based in part on our
expectations of future revenue, and we may be unable to adjust costs in a timely
manner in response to revenue shortfalls. This can result in significant
quarterly fluctuations in our operating results.

                                       11
<PAGE>
OUR LENGTHY AND VARIABLE QUALIFICATION AND SALES CYCLE MAKES IT DIFFICULT TO
PREDICT THE TIMING OF A SALE OR WHETHER A SALE WILL BE MADE, WHICH MAY HARM OUR
OPERATING RESULTS.

    Our customers typically expend significant efforts in evaluating and
qualifying our products and manufacturing process prior to placing an order.
This evaluation and qualification process frequently results in a lengthy sales
cycle, typically ranging from nine to twelve months and sometimes longer. While
our customers are evaluating our products and before they place an order with
us, we may incur substantial sales, marketing, research and development
expenses, expend significant management efforts, increase manufacturing capacity
and order long lead-time supplies. Even after this evaluation process, it is
possible a potential customer will not purchase our products for deployment. In
addition, product purchases are frequently subject to unplanned processing and
other delays, particularly with respect to larger customers for which our
products represent a very small percentage of their overall purchase activity.
Long sales cycles may cause our revenues and operating results to vary
significantly and unexpectedly from quarter to quarter, which could cause
volatility in our stock price.

WE DEPEND ON KEY PERSONNEL TO MANAGE OUR BUSINESS EFFECTIVELY IN A RAPIDLY
CHANGING MARKET, AND IF WE ARE UNABLE TO HIRE ADDITIONAL PERSONNEL, OUR ABILITY
TO SELL OUR PRODUCTS COULD BE HARMED.

    Our future success depends upon the continued services of our executive
officers, particularly Joseph Y. Liu, our Chief Executive Officer, Frederick R.
Fromm, our President, Alex Hsu, our President, Global Manufacturing Operations,
and other key engineering, finance, sales, marketing, manufacturing and support
personnel. In addition, we depend substantially upon the continued services of
key management personnel at our Chinese subsidiaries. None of our officers or
key employees is bound by an employment agreement for any specific term, and
these personnel may terminate their employment at any time. In addition, we do
not have "key person" life insurance policies covering any of our employees.


    As a result of the expansion of our operations, we must hire a significant
number of additional employees in the near future, particularly engineering,
sales and manufacturing personnel. Our ability to continue to attract and retain
highly-skilled personnel will be a critical factor in determining whether we
will be successful in the future. Competition for highly-skilled personnel is
intense, especially in the San Francisco Bay area. We may not be successful in
attracting, assimilating or retaining qualified personnel to fulfill our current
or future needs. In addition, many of the members of our management team have
just recently joined our company. Mr. Jingyu Xu, Senior Vice President of
Engineering, joined us in November 1999, Messrs. Zhimin Liu, our Chief
Scientist, and Bruce Horn, our Chief Financial Officer, joined us in
April 2000, Mr. Frederick R. Fromm, our President, joined us in July 2000, and
Messrs. Jeff Friedman, our Associate General Counsel, and Daryl Eigen, our Vice
President of Sales and Marketing, joined us in August 2000. If our new
management team does not work effectively together, it could seriously harm our
business.


A SUBSTANTIAL PORTION OF OUR MANUFACTURING OPERATIONS ARE LOCATED IN CHINA,
WHICH EXPOSES US TO THE RISK THAT OUR FAILURE TO COMPLY WITH THE LAWS AND
REGULATIONS OF CHINA, OR EVENTS IN THAT COUNTRY, WILL DISRUPT OUR OPERATIONS.

    A substantial portion of our manufacturing operations are located in China
and are subject to the laws and regulations of China. Our operations in China
may be adversely affected by changes in the laws and regulations of China, such
as those relating to taxation, import and export tariffs, environmental
regulations, land use rights, property and other matters. China's central or
local government may impose new, stricter regulations or interpretations of
existing regulations which would require additional expenditures. China's
economy differs from the economies of many countries in terms of structure,
government involvement, level of development, growth rate, capital reinvestment,
allocation of resources, self-sufficiency and rate of inflation, among others.
Our results of operations

                                       12
<PAGE>
and financial condition may be harmed by changes in the political, economic or
social conditions in China.

    In addition, events out of our control in China, such as political unrest,
war, labor strikes and work stoppages, could disrupt our operations. There is
currently political tension between the United States and China, which could
lead to a break down in trade relations. There is also significant tension
between China and Taiwan, which could result in hostilities. If any of these
events occurs, it would be difficult for us to establish manufacturing
operations at an alternative location on comparable terms.

    Our operations in China also expose us to the following general risks
associated with international operations:

    - difficulties and costs of staffing and managing foreign operations with
      personnel who have expertise in optical network technology;

    - unexpected changes in regulatory or certification requirements for optical
      systems or networks;

    - disruptions in the transportation of our products and other risks related
      to the infrastructure of foreign countries;

    - fluctuations in the value of currencies; and

    - economic instability.

BECAUSE SOME OF OUR THIRD-PARTY SALES REPRESENTATIVES AND DISTRIBUTORS CARRY
PRODUCTS OF ONE OR MORE OF OUR COMPETITORS, THEY MAY NOT RECOMMEND OUR PRODUCTS
OVER COMPETITORS' PRODUCTS.

    A majority of our revenues are derived from sales through our domestic and
international sales representatives and distributors. Our sales representatives
and distributors are independent organizations that generally have exclusive
geographic territories and generally are compensated on a commission basis. We
expect that we will continue to rely on our independent sales representatives
and distributors to market, sell and support many of our products. Some of our
third-party sales representatives and distributors carry products of one or more
of our competitors. As a result, these sales representatives and distributors
may not recommend our products over competitors' products.

IF WE DO NOT EXPAND OUR SALES ORGANIZATION, WE MAY FACE DIFFICULTIES IN
INCREASING MARKET AWARENESS AND SALES OF OUR PRODUCTS, WHICH COULD PREVENT US
FROM ACHIEVING AND MAINTAINING PROFITABILITY.

    We currently have a small sales force. We will need to hire additional
qualified sales personnel domestically and internationally to increase market
awareness and sales of our products. Competition for qualified sales personnel
in our industry is intense and we might not be able to hire and train the kind
and number of sales personnel we need to be successful. If we are unable to
expand our sales organization, we may not be able to increase market awareness
or sales of our products, which could prevent us from achieving and maintaining
profitability.

BECAUSE SOME OF OUR MANUFACTURING OPERATIONS ARE LOCATED IN ACTIVE EARTHQUAKE
FAULT ZONES, WE FACE THE RISK THAT A LARGE EARTHQUAKE COULD HARM OUR OPERATIONS.

    A substantial portion of our manufacturing operations are located in San
Jose, California, an active earthquake fault zone. This region has experienced
large earthquakes in the past and may likely experience them in the future. A
large earthquake in the San Jose area could disrupt our manufacturing operations
for an extended period of time, which would limit our ability to supply our
products to our customers in sufficient quantities on a timely basis, harming
our customer relationships.

                                       13
<PAGE>
OUR FAILURE TO COMPLY WITH GOVERNMENTAL REGULATIONS COULD SUBJECT US TO
LIABILITY.

    Our failure to comply with a variety of federal, state and local laws and
regulations in the United States and China could subject us to criminal, civil
and administrative penalties. Our products are subject to U.S. export control
laws and regulations that regulate the export of products and disclosure of
technical information to foreign countries. These laws and regulations may
require licenses for export to some of our products and disclosure of technology
to some countries, including China, where a substantial portion of our
manufacturing operations occur, and foreign citizens, including a number of our
employees. We plan to file an application shortly to obtain a commodity
classification confirming that we may export our products and disclose our
technology to foreign countries, including China, and citizens, including
Chinese nationals, without export licenses. In the event this classification is
not obtained, we have alternatively filed applications to obtain licenses
permitting us to disclose our technology to specified employees. However, we
cannot assure you that we will obtain these classification and licenses.
Furthermore, the Department of Commerce has initiated an inquiry as to whether
one of our employees received information in violation of licensing
requirements. We may be found to have violated export restrictions with respect
to this individual and in the past, which could result in criminal, civil and
administrative penalties, including the denial of export privileges. In
addition, we are subject to laws relating to the storage, use, discharge and
disposal of toxic or otherwise hazardous or regulated chemicals or materials
used in our manufacturing processes. While we believe that we are currently in
compliance in all material respects with these laws and regulations, if we fail
to store, use, discharge or dispose of hazardous materials appropriately, we
could be subject to substantial liability or could be required to suspend or
adversely modify our manufacturing operations. In addition, we could be required
to pay for the cleanup of our properties if they are found to be contaminated,
even if we are not responsible for the contamination. We employ a number of
foreign nationals in our U.S. operations and as a result we are subject to
various laws related to the status of those employees with the Immigration and
Naturalization Service. Our failure to comply with the forgoing laws or any
other laws and regulations could subject us to liability.

BECAUSE THE OPTICAL COMPONENTS INDUSTRY IS CAPITAL INTENSIVE, OUR BUSINESS MAY
BE HARMED IF WE ARE UNABLE TO RAISE ANY NEEDED ADDITIONAL CAPITAL.

    The optical components industry is capital intensive, and expansion of our
manufacturing facilities, the development and marketing of new products and the
hiring and retention of personnel will require a significant commitment of
resources. Furthermore, we may continue to incur significant operating losses if
the market for optical networking components develops at a slower pace than we
anticipate, or if we fail to establish significant market share and achieve a
significantly increased level of revenue. If cash from available sources is
insufficient for these purposes, or if additional cash is used for acquisitions
or other unanticipated uses, we may need to raise additional capital. Additional
capital may not be available on terms favorable to us, or at all. If we are
unable to raise additional capital when we require it, our business could be
harmed. In addition, any additional issuance of equity or equity-related
securities to raise capital will be dilutive to our stockholders.

BECAUSE THE OPTICAL COMPONENTS INDUSTRY IS EVOLVING RAPIDLY AND HIGHLY
COMPETITIVE, OUR STRATEGY INVOLVES ACQUIRING OTHER BUSINESSES AND TECHNOLOGIES
TO GROW OUR BUSINESS. IF WE ARE UNABLE TO SUCCESSFULLY INTEGRATE ACQUIRED
BUSINESSES OR TECHNOLOGIES, OUR OPERATING RESULTS MAY BE HARMED.

    The optical components industry is evolving rapidly and highly competitive.
Accordingly, we have pursued and expect to continue to pursue acquisitions of
businesses and technologies, or the establishment of joint venture arrangements,
that could expand our business. The negotiation of potential acquisitions or
joint ventures, as well as the integration of an acquired or jointly developed

                                       14
<PAGE>
business or technology, could cause diversion of management's time and other
resources or disrupt our operations. Future acquisitions could result in:

    - additional operating expenses without additional revenues;

    - potential dilutive issuances of equity securities;

    - the incurrence of debt and contingent liabilities;

    - amortization of goodwill and other intangibles;

    - research and development write-offs; and

    - other acquisition-related expenses.

    Furthermore, we may not be able to successfully integrate acquired
businesses or joint ventures with our operations, and we may not receive the
intended benefits of any future acquisition or joint venture.

              RISKS RELATED TO OUR COMMON STOCK AND THIS OFFERING

THERE MAY BE SALES OF A SUBSTANTIAL AMOUNT OF OUR COMMON STOCK AFTER THIS
OFFERING BY OUR STOCKHOLDERS AND THESE SALES COULD CAUSE OUR STOCK PRICE TO
DECLINE.


    At July 31, 2000, our current stockholders held 150,464,422 shares of our
common stock, including shares issuable upon conversion of outstanding preferred
stock upon consummation of this offering. In addition, at July 31, 2000, options
to purchase an aggregate of 22,363,744 shares were outstanding and warrants to
purchase an aggregate of 348,904 shares were outstanding. Our executive
officers, directors and stockholders holding an aggregate of 122,703,084 shares
of our common stock, or 94.8% of our total outstanding shares as of July 31,
2000, have executed lock-up agreements that prevent them from selling or
otherwise disposing of our common stock for a period of 180 days from the date
of this prospectus without the prior written approval of FleetBoston Robertson
Stephens Inc. These lock-up agreements will expire on             , 2000, and an
aggregate of 122,703,084 shares will be "restricted securities" as defined in
Rule 144. These restricted securities may be sold in the future without
registration under the Securities Act to the extent permitted under Rule 144,
Rule 701 or another exemption under the Securities Act. In addition, Cisco and
the holders of outstanding preferred stock are entitled to registration of their
shares of common stock and the shares of common stock issuable upon conversion
of their preferred stock under certain circumstances.


    Sales of a substantial number of shares of our common stock after this
offering could cause our stock price to fall. In addition, the sale of these
shares could impair our ability to raise capital through the sale of additional
stock in the future at a price that we deem appropriate.

INSIDERS WILL CONTINUE TO HAVE SUBSTANTIAL CONTROL OVER US AFTER THIS OFFERING
AND COULD DELAY A CHANGE IN OUR CORPORATE CONTROL, WHICH MAY NEGATIVELY AFFECT
YOUR INVESTMENT.

    Our officers, directors and their affiliates will own, in the aggregate, as
of July 31, 2000, approximately 28.6% of our outstanding shares after this
offering, or 28.2% if the underwriters' over-allotment option is exercised in
full. As a result, these persons and/or entities acting together will be able to
substantially influence the outcome of all matters requiring approval by our
stockholders, including the election of directors and approval of significant
corporate transactions. This ability may have the effect of delaying a change in
control, which may be favored by our other stockholders. See "Principal
Stockholders."

                                       15
<PAGE>
BECAUSE OF THE EARLY STAGE OF OUR BUSINESS AND THE RAPID CHANGES TAKING PLACE IN
THE FIBER OPTICS INDUSTRY, WE EXPECT TO EXPERIENCE SIGNIFICANT VOLATILITY IN OUR
STOCK PRICE, WHICH COULD CAUSE YOU TO LOSE ALL OR PART OF YOUR INVESTMENT.

    Because of the early stage of our business and the rapid changes taking
place in the fiber optics industry, we expect the market price of our common
stock to fluctuate significantly. These fluctuations may occur in response to a
number of factors, some of which are beyond our control, including:

    - quarterly variations in our operating results;

    - changes in financial estimates by securities analysts and our failure to
      meet any estimates;

    - changes in market values of comparable companies;

    - announcements by us or our competitors of new products or of significant
      acquisitions, strategic partnerships or joint ventures;

    - any loss by us of a major customer;

    - the outcome of, and costs associated with, any litigation to which we are
      or may become a party;

    - additions or departures of key management or engineering personnel; and

    - future sales of our common stock.

    We determined the initial public offering price based on negotiations with
the representatives of the underwriters and based on factors that may not be
indicative of future market performance. The initial public offering price may
bear no relationship to the price at which the common stock will trade
subsequent to the completion of this offering.

PROVISIONS OF OUR CHARTER DOCUMENTS AND DELAWARE LAW MAY HAVE ANTI-TAKEOVER
EFFECTS THAT COULD PREVENT ANY CHANGE IN CONTROL, WHICH COULD NEGATIVELY AFFECT
YOUR INVESTMENT.

    Provisions of Delaware law and of our certificate of incorporation and
bylaws could make it more difficult for a third party to acquire us, even if
doing so would be beneficial to our stockholders. These provisions permit us to:

    - issue preferred stock with rights senior to those of the common stock
      without any further vote or action by the stockholders;

    - provide for a classified board of directors;

    - eliminate the right of the stockholders to call a special meeting of
      stockholders;

    - eliminate the right of stockholders to act by written consent; and

    - impose various procedural and other requirements which could make it
      difficult for stockholders to effect certain corporate actions.

    Any of the foregoing provisions could limit the price that certain investors
might be willing to pay in the future for shares of our common stock.

                   NOTE REGARDING FORWARD-LOOKING STATEMENTS

    This prospectus contains forward-looking statements that involve risks and
uncertainties. These statements relate to our future plans, objectives,
expectations and intentions, and the assumptions underlying or relating to any
of these statements. These statements may be identified by the use of words such
as "expect," "anticipate," "intend," "plan," "will" and similar expressions. Our
actual results could differ materially from those discussed in these statements.
Factors that could contribute to such differences include those discussed in
"Risk Factors," "Business," "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and elsewhere in this prospectus.

                                USE OF PROCEEDS


    The net proceeds we will receive from the sale of the 13,700,000 shares of
common stock offered by us are estimated to be $138.4 million, or
$159.4 million if the underwriters' over-allotment option is exercised in full,
after deducting the estimated underwriting discounts and commissions and the
estimated offering expenses payable by us based on an assumed initial public
offering price of $11.00 per share. In addition, we have received $50.0 million
in connection with the issuance to Cisco Systems of a promissory note which will
convert automatically into shares of common stock upon the closing of this
offering.


    The principal purposes of this offering are:

    - to obtain additional capital;

    - to create a public market for our common stock;

    - to increase our visibility and credibility; and

    - to facilitate future access to the public equity markets.

    We intend to use the net proceeds we receive from the offering for expansion
of manufacturing facilities, marketing and distribution activities, research and
development activities, working capital and other general corporate purposes.
During the next twelve months, we expect to use approximately $60 million for
the expansion of our manufacturing facilities. In addition, we anticipate using
a portion of the net proceeds for strategic acquisitions of businesses and
technologies. However, we have no specific agreements or commitments and are not
currently engaged in any negotiations with respect to any material acquisitions.
Accordingly, our management will retain broad discretion as to the allocation of
the net proceeds of this offering. We intend to invest the net proceeds of this
offering in short-term, interest-bearing investment grade securities until they
are used.

                                DIVIDEND POLICY

    We have never declared or paid dividends on our capital stock and do not
anticipate paying any dividends in the foreseeable future. We currently intend
to retain our earnings, if any, for the development of our business.

                                 CAPITALIZATION

    The following table sets forth our capitalization as of June 30, 2000:

    - on an actual basis;


    - on a pro forma basis to reflect the conversion of all shares of our
      convertible preferred stock outstanding as of June 30, 2000 into
      110,103,344 shares of common stock upon completion of this offering and
      the receipt of $50.0 million from Cisco Systems pursuant to a convertible
      note payable; and



    - on a pro forma as adjusted basis to reflect our receipt of the net
      proceeds from the sale of 13,700,000 shares of common stock by us at an
      assumed public offering price of $11.00 per share less estimated
      underwriting discounts and commissions and estimated offering expenses and
      the conversion of the principal and accrued interest on the note payable
      to Cisco Systems into shares of our common stock at a conversion price
      equal to 85% of the public offering price. Assuming a public offering
      price of $11.00 and a closing date of September 30, 2000, the note would
      convert into 5,386,272 shares of common stock. Pro forma as adjusted
      accumulated deficit reflects recording of interest expense of
      $8.8 million, representing the beneficial conversion feature of the note
      payable and accrued interest of $362,000 on the note payable.

                                    DILUTION


    Our pro forma net tangible book value at June 30, 2000 was approximately
$48.6 million, or $0.36 per share after giving effect to the conversion of all
outstanding shares of our convertible preferred stock into shares of common
stock upon completion of this offering. Pro forma net tangible book value per
share is equal to our total tangible assets less our total liabilities, divided
by the total number of shares of our common stock outstanding. After giving
effect to the sale of the 13,700,000 shares of our common stock offered in this
offering at an assumed initial public offering price of $11.00 per share, after
deducting estimated underwriting discounts and commissions and estimated
offering expenses payable by us, and conversion of our convertible note payable
to Cisco into 5,386,272 shares of our common stock, our pro forma as adjusted
net tangible book value at June 30, 2000 would have been approximately
$228.2 million or $1.49 per share. This represents an immediate increase in net
tangible book value of $1.13 per share to existing stockholders and an immediate
dilution of $9.51 per share to new investors purchasing shares of our common
stock in this offering. The following table illustrates the per share dilution
to the new investors:

    - 24,962,888 shares of common stock reserved for issuance upon exercise of
      outstanding options at June 30, 2000 with a weighted average exercise
      price of $0.8278 per share;

    - 348,904 shares of common stock issuable upon exercise of outstanding
      warrants with a weighted average exercise price of $0.1720 per share; and

      1998 Stock Plan, 2000 Employee Stock Purchase Plan and 2000 Equity
      Incentive Plan.

    Assuming the exercise of all options and warrants outstanding as of

                      SELECTED CONSOLIDATED FINANCIAL DATA

    The following selected consolidated financial data should be read in
conjunction with, and are qualified by reference to, our consolidated financial
statements and related notes and "Management's Discussion and Analysis of
Financial Condition and Results of Operations." The selected consolidated
statement of operations data for the fiscal years ended June 30, 1997, 1998,
1999 and 2000 and selected consolidated balance sheet data as of June 30, 1998,
1999 and 2000 are derived from, and qualified by reference to, the audited
consolidated financial statements. The selected consolidated statement of
operations data for the fiscal year ended June 30, 1996 and the selected
consolidated balance sheet data as of June 30, 1996 and 1997 are derived from
unaudited financial statements not included in this prospectus. Net loss per
share is not presented for the years ended June 30, 1996 and 1997, as there were
no common shares outstanding during these periods and common stock equivalents
would be anti-dilutive to our net loss per share.

    The unaudited consolidated financial statements have been prepared by us on
a basis consistent with our audited consolidated financial statements and, in
the opinion of management, include all adjustments, consisting only of normal
recurring adjustments, necessary for a fair presentation of our results of

future period.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

    THE FOLLOWING DISCUSSION AND ANALYSIS OF OUR FINANCIAL CONDITION AND RESULTS
OF OPERATIONS SHOULD BE READ IN CONJUNCTION WITH "SELECTED CONSOLIDATED
FINANCIAL DATA" AND OUR FINANCIAL STATEMENTS AND RELATED NOTES INCLUDED
ELSEWHERE IN THIS PROSPECTUS. IN ADDITION TO HISTORICAL INFORMATION, THE
DISCUSSION IN THIS PROSPECTUS CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE
RISKS AND UNCERTAINTIES. OUR ACTUAL RESULTS COULD DIFFER MATERIALLY FROM THOSE
ANTICIPATED BY THESE FORWARD-LOOKING STATEMENTS DUE TO FACTORS INCLUDING, BUT
NOT LIMITED TO, THOSE FACTORS SET FORTH UNDER "RISK FACTORS" AND ELSEWHERE IN
THIS PROSPECTUS.

OVERVIEW

    We design, manufacture and market fiber optic components and integrated
optical modules that increase the performance of optical networks. We provide a
broad line of products to communication equipment suppliers to enable bandwidth
creation and management within an optical network. We incorporated in
September 1995 and began shipping product for sale in the second half of 1996.
In April 1999, we established manufacturing operations in Zhuhai, China. In
April 2000, we acquired Telelight Communications Inc., a designer and
manufacturer of fiber optic components with operations in Sunnyvale, California
and Fuzhou, China.

    We generate revenues from the sale of fiber optic components and integrated
optical modules. To date, we have developed over 20 types of primary components.
In addition, we have integrated these components through various combinations
and are able to provide over 100 customized solutions for our customers. Our
products are generally categorized into the following four major groups:
wavelength expansion, optical amplification, wavelength performance monitoring
and protection and optical switching. The vast majority of our revenues are
derived from our wavelength expansion products, in particular, dense wavelength
division multiplexers, or DWDMs, and noise reduction filters.

    We sell our products through our direct sales force, sales representatives
and distributors. For the year ended June 30, 2000, we sold our products to over
100 communication equipment suppliers. A relatively small number of these
suppliers have accounted for a significant portion of our revenues to date, and
we expect this trend to continue for the foreseeable future. For the year ended
June 30, 2000, sales to Lucent Technologies, Sycamore Networks and JDS Uniphase
accounted for 42.6%, 15.7% and 10.6% of revenues. Sales to Lucent are made to
three different groups within the Lucent organization, each making its own
purchasing decisions. Sales to the Optical Network Group, the Optical
Electronics Group and Bell Labs comprised 31.9%, 10.3% and 0.4% of our revenues
for the year ended June 30, 2000. Lucent has indicated that it may decrease and
eventually discontinue incorporating one of our products into some of its
products over the next two years. Lucent's purchases of these products
represented 28.3% of our revenues for the year ended June 30, 2000. For the
years ended June 30, 1999, and 2000, sales to international customers
represented 23.2% and 20.7% of revenues. All of our sales are transacted in U.S.
dollars.

    Except for sales to Lucent, we recognize revenues from product sales at the
time the product is shipped to our customers, including our distributors,
provided there are no significant uncertainties with respect to customer
acceptance or collection. Our distributors do not have the right to return or
exchange products. Substantially all shipments to Lucent are on a consignment
basis, and we do not recognize revenues until Lucent accepts the products for
use. In most cases, Lucent will accept products and we will recognize revenues
within one to two months of shipment. We continue to report products shipped to
Lucent as our inventory until they are accepted.

    We have manufacturing operations in San Jose, California and Zhuhai and
Fuzhou, China. We have expanded and plan to continue to expand our manufacturing
capacity as our business grows. We are currently expanding our facilities in San
Jose and Zhuhai. In addition, we have acquired rights to a parcel of land in
China which we intend to use for future expansion of our manufacturing
facilities.

                                       23

    COST OF REVENUES.  Our cost of revenues consists of raw material, salaries
and related personnel expense, manufacturing overhead, and provisions for excess
and obsolete inventories and warranties. We expect cost of revenues, as a
percentage of revenues, to fluctuate from period to period. Our gross margins
will primarily be affected by production yield, provisions for excess and
obsolete inventories, our pricing policies, mix of products sold, costs incurred
in establishing additional manufacturing lines and facilities, and manufacturing
volume. The fiber optic component industry is typically characterized by rapidly
declining average selling prices, increasing unit volumes and declining margins.

    RESEARCH AND DEVELOPMENT EXPENSES.  Our research and development expenses
consist primarily of salaries and related personnel costs, fees paid to
consultants and outside service providers, patent filing costs, non-recurring
engineering charges and prototype costs, all of which relate to the design,
development, testing, pre-manufacturing and significant improvement of our
products. We expense our research and development costs as they are incurred. We
believe that developing customer solutions at the prototype stage is critical to
our strategic product development objectives. We further believe that, in order
to meet the changing requirements of our customers, we will need to fund
investments in several concurrent product development projects. As a result, we
expect our research and development expenses to increase in absolute dollar
amount and as a percentage of revenues in the future.

    SALES AND MARKETING EXPENSES.  Our sales and marketing expenses consist
primarily of salaries and related expenses for marketing, sales, customer
service and application engineering support personnel, commissions paid to the
internal sales personnel and representatives, as well as costs associated with
promotional and other marketing expenses. We intend to expand our direct sales
operations, as well as engage additional sales representatives and distributors
to increase market awareness and revenues. As we hire additional sales and
marketing personnel, initiate additional marketing programs to support our
products and establish sales offices, we expect that sales and marketing
expenses will increase in absolute dollar amount over the next year but remain
approximately at the current percentage of revenues.

    GENERAL AND ADMINISTRATIVE EXPENSES.  Our general and administrative
expenses consist primarily of salaries and related expenses for executive,
finance, accounting, and human resources personnel, professional fees and other
corporate expenses. As we add personnel and incur additional costs related to
the growth of our business and our operation as a public company, we expect
general and administrative expenses to increase in absolute dollar amount but
decrease as a percentage of revenues.

    AMORTIZATION OF DEFERRED STOCK COMPENSATION.  We granted stock options and
issued warrants to employees consultants at prices subsequently deemed to be
below the fair value of the underlying stock on the date of grant or issuance.
During the period from July 1, 1998 through June 30, 2000, we recorded aggregate
deferred stock compensation of approximately $33.8 million, of which
$3.0 million was expensed during the year ended June 30, 1999 and $12.7 million
was expensed during the year ended June 30, 2000. While this expense has
increased our net loss, it has no impact on our cash flows. With respect to
employee stock-based compensation, we are amortizing the deferred compensation
expense over the vesting period using the multiple option approach. Non-employee
grants are accounted for in accordance with SFAS 123 and EITF 96-18 and valued
using the Black-Scholes model. The remaining $18.1 million will be expensed in
future periods generally over a four-year vesting period.

    Subsequent to June 30, 2000, we have issued shares and granted options that
will result in an additional $21.8 million of deferred stock compensation. We
estimate that our deferred stock compensation expense from options and shares
granted or issued from July 1998 through August 18, 2000 will be $8.3 million,
$6.1 million, $4.8 million and $3.9 million for each of the fiscal quarters in
the year ended June 30, 2001, and $10.4 million, $4.9 million and $1.4 million,
for the years ending June 30, 2002, 2003 and 2004, assuming no cancellations or
additional stock option grants with exercise prices below below deemed fair
value of our common stock.

CONVERTIBLE NOTE PAYABLE



    On August 28, 2000, we received $50,000,000 in exchange for a note payable
to Cisco Systems, Inc. The note payable accrues interest at a rate of 8% per
annum. Upon the closing of our initial public offering, the note payable and any
unpaid accrued interest will, subject to obtaining regulatory approval,
automatically convert into shares of our common stock at a conversion price per
share equal to 85% of the initial public offering price per share. Assuming an
initial public offering price of $11.00 per share and a closing date of
September 30, 2000, the note would convert into 5,386,272 shares of common
stock. Upon the closing of our initial public offering, we expect to record
interest expense of $8.8 million, representing the beneficial conversion feature
of this note payable.


    ACQUISITION OF TELELIGHT.  We entered into a definitive agreement to acquire
Telelight in February 2000 in a merger transaction accounted for as a purchase
business combination. The acquisition was consummated on April 6, 2000. The
results of operations of Telelight are included in our consolidated financial
statements beginning on the date of the acquisition. The purchase price of
Telelight consisted of 13,440,000 shares of our common stock valued at
$26.9 million. We also incurred direct acquisition costs of approximately
$200,000 resulting in an aggregate purchase price of $27.1 million. Telelight
was founded in 1998 to design, develop and sell fiber optic components which are
designed to increase capacity and bandwidth of fiber optic communications
networks. The purchase price was allocated to the tangible and identifiable
intangible assets acquired and liabilities assumed on the basis of their
relative fair values as follows:

                                                              $27,080

</TABLE>

    The net tangible assets of Telelight consist primarily of cash and cash
equivalents, accounts receivable, inventory, property and equipment, accounts
payable and other liabilities.

    The developed technologies acquired in the Telelight acquisition were the
optical circulator and filter products. These products have yet to gain market
acceptance or receive certain industry-standard qualifications. Given these
facts and the commodity nature of these products, minimal value was attributed
to them in the purchase price allocation.

    The in-process research and development consisted of an optical wavelength
interleaver product that, as of the date of acquisition, had not yet reached
technological feasibility and had no alternative future use. The optical
interleaver is a compact high performance fiber optic product that segments
optical signals by wavelengths. This product makes channel spacing smaller,
thereby increasing the number of channels on a fiber optic network.

    The value of the optical wavelength interleaver was determined by estimating
the net cash flows from the sale of the products resulting from the completion
of this project, reduced by the portion of the net cash flows from the revenue
attributable to core technology. The resulting cash flows were then discounted
back to their present value using a discount rate of 35%. The fair value
assigned to the core technology totaled $6,245,000, and is being amortized over
the expected life of its cash flows of four years. At the time of the
acquisition this project was approximately 80% complete. The fair value assigned
to the in-process research and development totaled $7,020,000, and was charged
to expense at

                                       25
<PAGE>
the time of the acquisition. We have incurred approximately $50,000 of expense
subsequent to the acquisition, and in May 2000 the first qualified prototype was
completed and technological feasibility was achieved.

    The value of certain patents being assigned to us was determined using the
relief from royalty methodology, which assumes that the value of the asset
equals the amount a third party would pay to use the asset and capitalize on the
related benefits of the assets. The fair value assigned to patents of $1,086,000
is being amortized over its expected life of four years.

    Goodwill is being amortized on a straight line basis over the estimated
period of benefit of four years.

</TABLE>

RESULTS OF OPERATIONS FOR THE FISCAL YEARS ENDED JUNE 30, 1999 AND 2000

    REVENUES.  Revenues increased $29.9 million, or 329%, from $9.1 million for
the year ended June 30, 1999 to $39.0 million for the year ended June 30, 2000.
This increase in revenues was primarily due to increased shipments of our
existing wavelength expansion products to existing customers and to a lesser
extent shipments of existing products to new customers and shipments of new
products to new and existing customers. This increase was offset by a decrease
in the price of a product sold to Lucent and a decrease in the average selling
price of some of our other products.

    GROSS PROFIT (LOSS).  Gross profit increased $3.8 million, or 205%, from
$1.9 million for the year ended June 30, 1999 to $5.7 million for the year ended
June 30, 2000. This resulted in a decrease in gross margins from 20.6% to 14.6%.
The decrease in our gross margin was substantially the result of a decrease in
the average selling price of some of our products and the recording of a
provision for excess and obsolete inventory of $4.7 million for the year ended
June 30, 2000 compared to a provision of $555,000 in the year ended June 30,
1999. This decrease was partially offset by increased unit shipments of our
products and economies of scale resulting from higher production volumes. The

                                       26
<PAGE>
increase in inventory reserve is the result of inventory levels exceeding the
amounts that we anticipate using over the period of time specified in our
reserve policy. We expect to continue to incur excess and obsolete inventory
costs; however, the magnitude is not determinable. Gross profit, including
amortization of deferred compensation, increased $2.2 million, or 195%, from
$1.2 million in the year ended June 30, 1999 to $3.4 million for the year ended
June 30, 2000. This resulted in a decrease in gross margins from 12.8% to 8.8%.

    RESEARCH AND DEVELOPMENT.  Research and development expenses increased
$3.1 million, or 489%, from $626,000 for the year ended June 30, 1999 to
$3.7 million for the year ended June 30, 2000. The increase in research and
development expenses was substantially due to increases in personnel-related
costs and prototype expenses. The personnel-related costs increased due to an
increase in average personnel from 12 in the year ended June 30, 1999 to 40 in
the year ended June 30, 2000. Research and development expenses, including
amortization of deferred compensation, increased $4.2 million or 331% from
$1.3 million for the year ended June 30, 1999 to $5.5 million for the year ended
June 30, 2000.

    SALES AND MARKETING.  Sales and marketing expenses increased $1.9 million,
or 236%, from $802,000 for the year ended June 30, 1999 to $2.7 million for the
year ended June 30, 2000. The increase in sales and marketing expense was
substantially due to increases in sales and marketing personnel and related
costs, commission expenses to our internal and external sales representatives
and tradeshow, advertising and other customer-related costs. The increase in
personnel and related costs is due to an increase in the average number of
personnel from six in the year ended June 30, 1999 to an average of 11 in the
year ended June 30, 2000. Sales and marketing expenses, including amortization
of deferred compensation, increased $2.7 million or 202% from $1.3 million for
the year ended June 30, 1999 to $4.0 million for the year ended June 30, 2000.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased
$3.3 million, or 405%, from $826,000 for the year ended June 30, 1999 to
$4.2 million for the year ended June 30, 2000. The increase in general and
administrative expenses was substantially due to increases in personnel and
related costs, legal and employee recruiting fees and bad debt reserves. The
increase in personnel and related costs is due to an increase in the average
number of personnel from three in the year ended June 30, 1999 to an average of
15 in the year ended June 30, 2000. General and administrative expenses,
including amortization of deferred compensation, increased $9.5 million or 482%
from $2.0 million for the year ended June 30, 1999 to $11.5 million for the year
ended June 30, 2000.

    AMORTIZATION OF DEFERRED COMPENSATION.  Through June 30, 2000, we have
recorded a total of $33.8 million in deferred compensation. Amortization of
deferred compensation expenses increased $9.7 million, or 320%, from
$3.0 million for the year ended June 30, 1999 to $12.7 million for the year
ended June 30, 2000.

    ACQUIRED IN-PROCESS RESEARCH AND DEVELOPMENT AND AMORTIZATION OF
GOODWILL.  In-process research and development and amortization of goodwill
represents charges incurred as a result of our acquisition of Telelight in
April 2000. See Note 4 of the Notes to the Consolidated Financial Statements for
additional information.

    INTEREST AND OTHER INCOME (EXPENSE), NET.  Interest and other income
(expense) for the year ended June 30, 1999 was $57,000 of expense as compared to
$689,000 of income for the year ended June 30, 2000. This increase in income is
due to larger cash balances from the proceeds of our preferred stock financing
in February 2000.

    PROVISION FOR INCOME TAXES.  We incurred operating losses for tax purposes
on the year ended June 30, 1999 and 2000 and therefore reported no provision for
income taxes in either period. As of

                                       27
<PAGE>
June 30, 2000, we had an insignificant taxable income and no significant net
operating loss carryforwards.

RESULTS OF OPERATIONS FOR THE FISCAL YEARS ENDED JUNE 30, 1998 AND 1999

    REVENUES.  Our revenues were $2.5 million and $9.1 million for the years
ended June 30, 1998 and 1999. This change represents an increase of 265%. The
majority of the increase in revenue is attributable to shipments of new products
and to a lesser extent shipments of products to new customers.

    GROSS PROFIT (LOSS).  Our gross profit (loss) was $(471,000) and
$1.9 million for the years ended June 30, 1998 and 1999. Our gross profit of
$1.9 million for year ended June 30, 1999 represented 20.6% of revenues. The
improvement in our gross margin was primarily the result of increased unit
shipments of our products, combined with a decrease in the cost of materials
that are used in our products and economies of scale associated with higher
production levels.

    RESEARCH AND DEVELOPMENT.  Research and development expenses were $455,000
and $626,000 for the years ended June 30, 1998 and 1999. This change represents
an increase of 38% and was primarily due to increases in personnel-related costs
as a result of increased personnel and prototype expenses.

    SALES AND MARKETING.  Sales and marketing expenses were $527,000 and
$802,000 for the years ended June 30, 1998 and 1999. This change represents an
increase of 52% and was primarily due to increases in sales and marketing
personnel and related costs as a result of increased personnel, commission
expenses, tradeshow, advertising and other customer-related costs.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses were
$683,000 and $826,000 for the years ended June 30, 1998 and 1999. This change
represents an increase of 21% and was primarily due to increases in personnel
and related costs as a result of increased personnel.

    AMORTIZATION OF DEFERRED COMPENSATION.  Through June 30, 1999, we recorded a
total of $6.5 million in deferred stock compensation. We recognized amortization
of stock compensation of $3.0 million for the year ended June 30, 1999, and none
during the year ended June 30, 1998.

    INTEREST AND OTHER INCOME (EXPENSE), NET.  Interest and other expense for
the years 1998 and 1999 was $12,000 and $57,000. The increase in expense was
primarily due to lease cancellation charges.

    PROVISION FOR INCOME TAXES.  We incurred operating losses during the years
1998 and 1999 and had no provision for income taxes in any of these periods. As
of June 30, 1999, we had $3.3 million in net operating losses, which are
available to offset future income subject to an annual limitation of $500,000.
If not used, the net operating losses will expire between 2004 and 2019.

</TABLE>

    Revenues increased in each of the eight quarters ended June 30, 2000. These
quarterly increases were primarily due to the increased volume shipments of new
and existing wavelength expansion products to new and existing customers. These
increases were offset by a decrease in the average selling price of some of our
products and, in particular, by a decrease in the price of a product sold to
Lucent during the quarters ended September 30, 1999 and December 31, 1999.

    Both gross profit and gross margins increased in each of the four quarters
ended June 30, 1999 primarily as a result of higher unit shipment volumes and
the economies of scale associated with the higher production levels. Gross
profit and gross margins decreased in the quarter ended September 30,

                                       29
<PAGE>
1999 from the prior quarter due to a significant drop in the average selling
price of a product sold to Lucent. Gross profits increased in the quarter ended
December 31, 1999 compared to the quarter ended September 30, 1999 primarily due
to higher unit shipments partially offset by a further decrease in the average
selling price of a product sold to Lucent. Gross margin decreased in this
quarter primarily due to the lower average selling price of a product sold to
Lucent. Gross profit and gross margins for the quarter ended March 31, 2000
decreased from the prior quarter primarily as a result of a significant increase
in the provision for excess and obsolete inventory. The gross profit increase in
the quarter ended June 30, 2000 compared to the prior quarter was primarily due
to higher unit shipments and a lower provision for excess and obsolete
inventory. Gross margins increased in the quarter ended June 30, 2000 compared
to the prior quarter due to a lower provision for excess and obsolete inventory.
We expect gross margins to fluctuate in the future as average selling prices
decline in our current products, as we incur higher manufacturing costs, as
production yields fluctuate, as we provide for excess and obsolete inventories,
as the mix of products changes, as we introduce new products which may have
higher margins, and as we increase our production capacity.

    Research and development, sales and marketing and general and administrative
expenses have increased over the eight quarters ended June 30, 2000 primarily
due to the addition of personnel, costs incurred for the development of new
products, increases in sales commissions, promotional expenses, professional
fees and bad debt reserves.

    Amortization of deferred compensation has fluctuated during the six quarters
ended June 30, 2000 primarily due to the timing of the granting of stock options
to employees and consultants of Oplink, partially offset by the timing of
adjustments made to deferred compensation resulting from forfeitures of stock
options upon termination of employment. These expenses may continue to fluctuate
in the future depending on the timing of stock option grants and forfeitures.

    Due to the factors noted above and other factors noted under "Risk Factors,"
we believe that quarter-to-quarter comparisons of our operating results will not
be meaningful. You should not rely on our results for any one quarter as an
indication of our future performance.

LIQUIDITY AND CAPITAL RESOURCES


    Since our inception, we have financed our operations primarily through
venture capital and private issuances of our convertible preferred stock, which
totaled approximately $58.4 million in aggregate net proceeds through June 30,
2000. In February 2000, we raised $44.0 million from venture capital and private
investors through the issuance of convertible preferred stock. As of June 30,
2000, we had cash and cash equivalents of $26.7 million and working capital of
$30.6 million. In August 2000, we received $50.0 million in connection with the
issuance to Cisco Systems of a promissory note which will, subject to regulatory
approval, convert automatically into shares of common stock upon the closing of
this offering.


    Our operating activities used cash of $2.1 million in fiscal 1998, $537,000
in fiscal 1999, and $7.1 million in fiscal 2000. Cash used in operating
activities was primarily attributable to net losses incurred during fiscal 1998,
1999 and in fiscal 2000 of $2.1 million, $3.5 million and $24.9 million. In
fiscal 1998, cash used in operating activities was also attributable to
increases in accounts receivable, inventories, and prepaid expenses of $509,000,
$184,000, and $174,000, partially offset by increases in accounts payable and
accrued liabilities of $280,000 and $210,000, respectively, depreciation and
amortization expense of property and equipment of $179,000 and provisions for
excess and obsolete inventory of $224,000. In fiscal 1999, cash used in
operating activities was also attributable to increases in accounts receivable,
inventories and prepaid expenses of $1.2 million, $2.5 million and $480,000,
partially offset by increases in accounts payable and accrued liabilities of
$2.8 million and $574,000, depreciation and amortization of property and
equipment of $267,000, amortization of deferred compensation of $3.0 million,
and provision for excess and obsolete inventory of $555,000. In fiscal

                                       30
<PAGE>
2000, cash used in operating activities was also attributable to increases in
accounts receivable, inventories and prepaid expenses of $8.1 million,
$13.6 million and $3.1 million, partially offset by increases in accounts
payable and accrued liabilities of $11.2 million and $4.6 million, depreciation
and amortization of property and equipment of $1.2 million, amortization of
goodwill and intangible assets of $1.4 million, amortization of deferred
compensation of $12.7 million provision for excess and obsolete inventory of
$4.7 million and acquired in-process research and development of $7.0 million.

    Our investing activities used cash of $411,000 in fiscal 1998, $1.4 million
in fiscal 1999, and $18.0 million in fiscal 2000. Our investing activities
primarily reflect the purchase of property and equipment. During the next
12 months we expect to expend approximately $60 million related primarily to the
expansion of our manufacturing facilities. We expect to use cash generated from
the offering for these expenditures.

    Our financing activities provided cash of $3.3 million in fiscal 1998,
$5.7 million in fiscal 1999, and $46.9 million in fiscal 2000. The increase in
cash in each of these periods was primarily from the net proceeds from the
issuances of our convertible preferred stock.


    Our principal source of liquidity at June 30, 2000 consisted of
$26.7 million in cash and cash equivalents. We believe that the proceeds from
this offering and cash received from Cisco Systems in exchange for a promissory
note in a principal amount of $50.0 million, together with our current cash and
cash equivalent balances, and any cash generated from operations, will be
sufficient to meet our operating and capital requirements for at least the next
12 months. However, it is possible that we may require additional financing
within this period. We have no current plans, and we are not currently
negotiating, to obtain additional financing following the completion of this
offering. The factors described above will affect our future capital
requirements and the adequacy of our available funds. In addition, even if we
raise sufficient funds to meet our anticipated cash needs during the next
12 months, we may need to raise additional funds beyond this time. We may be
required to raise those funds through public or private financings, strategic
relationships or other arrangements. We cannot assure you that such funding, if
needed, will be available on terms attractive to us, or at all. Furthermore, any
additional equity financing may be dilutive to stockholders, and debt financing,
if available, may involve restrictive covenants. If we fail to raise capital
when needed, our failure could have a negative impact on our ability to pursue
our business strategy and achieve and maintain profitability.


QUALITATIVE AND QUANTITATIVE MARKET RISK

    The primary objective of our investment activities is to preserve principal
while at the same time maximizing the income we receive from our investments
without significantly increasing risk. Some of the securities that we may invest
in may be subject to market risk. To minimize this risk in the future, we intend
to maintain our portfolio of cash equivalents and short-term investments in a
variety of securities, including commercial paper, money market funds,
government and non-government debt securities and certificates of deposit. As of
June 30, 2000, all of our investments were in money market funds, certificates
of deposits or high quality commercial paper.

RECENT ACCOUNTING PRONOUNCEMENTS

    In June 1998, the Financial Accounting Standards Board, or FASB, issued SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities". SFAS
No. 133 establishes new standards of accounting and reporting for derivative
instruments and hedging activities. SFAS No. 133 requires that all derivatives
be recognized at fair value in the statement of financial position, and that the
corresponding gains or losses be reported either in the statement of operations
or as a component of comprehensive income (loss), depending on the type of
hedging relationship that exists.

                                       31

    In July 1999, the FASB issued SFAS No. 137 "Accounting for Derivative
Instruments and Hedging Activities--Deferral of the Effective Date of FASB
Statement No. 133." SFAS No. 137 deferred the effective of SFAS No. 133 until
fiscal years beginning after June 15, 2000. We do not believe that the adoption
of SFAS No. 137 will have a material impact on our operations or financial
position.

    In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin, or SAB, No. 101, "Revenue Recognition in Financial
Statements, "which provides guidance on the recognition, presentation, and
disclosure of revenue in financial statements filed with the SEC. SAB 101
outlines the basic criteria that must be met to recognize revenue and provides
guidance for disclosures related to revenue recognition policies. We believe
that we have complied with the guidance of SAB 101.

    In March 2000, the Financial Accounting Standards Board issued
Interpretation No. 44, or FIN 44, "Accounting for Certain Transactions Involving
Stock Compensation, an Interpretation of Opinion No. 25" for (a) the definition
of employee for purposes of applying Opinion No. 25, (b) the criteria for
determining whether a plan qualifies as a noncompensatory plan, (c) the
accounting consequences of various modifications to the terms of a previously
fixed stock option or award, and (d) the accounting for an exchange of stock
compensation awards in a business combination. FIN 44 is effective July 1, 2000,
but certain conclusions cover specific events that occur after either
December 15, 1998, or January 12, 2000. The adoption of certain provisions of
FIN 44 prior to March 31, 2000 did not have a material impact on the financial
statements. Management does not expect that the adoption of the remaining
provisions will have a material effect on our financial position or results of
operations.

    In various areas, including revenue recognition, accounting standards and
practices continue to evolve. Additionally, the SEC is preparing to issue
interpretative guidance relating to SAB 101, and the FASB's Emerging Issues Task
Force continues to address revenue related accounting issues. We believe we are
in compliance with all of the rules and related guidance as they currently
exist. However, any changes to generally accepted accounting principles in these
areas could impact our future accounting for our operations.

INDUSTRY BACKGROUND

INCREASE IN BANDWIDTH DEMAND

    The rapid growth in Internet usage for activities such as electronic
commerce and large data and video file transmission has caused a significant
increase in data traffic across communication networks. According to Ryan,
Hankin & Kent, or RHK, a leading market research and consulting firm, Internet
traffic will increase from 0.4 million terabytes, or trillions of bytes, per
month at the end of 1999 to over 15 million terabytes per month in 2003, a
compound annual growth rate of 156%. The growth in Internet usage has created
significant demand for increased network capacity, or bandwidth, causing
communication service providers to expand and upgrade their network systems at a
rapid rate.

EVOLUTION OF THE OPTICAL NETWORK

    Communications networks were designed to convey voice rather than high-speed
data traffic. These networks are based on the transmission of electronic signals
over copper wires and are limited in their ability to handle large quantities of
data. As a result, communication service providers are increasingly adopting
fiber optic technology, which can handle large quantities of data more
effectively by transmitting signals using pulses of light rather than electric
signals. Fiber optic equipment consists of both passive and active components.
Passive optical components guide, mix, filter, route, adjust and stabilize
optical signals transmitted through an optical network and generally do not
require power to operate. Active components, in contrast, require power and use
electrical signals to create, modulate or amplify the original optical signal.
While fiber optic technology has existed for decades, recent technological
advances in the design and production of both passive and active components have
enabled communications equipment suppliers to develop next-generation fiber
optic systems. These components increase the capacity of existing optical
networks and enable the management of optical signals within the network. RHK
estimates that the market for fiber optic components was approximately
$6.7 billion in 1999 and anticipates that it will grow to approximately
$23.1 billion in 2003.

    BANDWIDTH CREATION.  Communication equipment suppliers may increase the
capacity of their customers' networks and transmit optical signals over greater
distances through the use of bandwidth creation technologies.

    - OPTICAL AMPLIFICATION.  Prior to the development of fiber amplifiers,
      signal attenuation, or loss, limited the distance to approximately 60
      miles over which an optical signal could be transmitted without
      regeneration. As a result, amplification equipment was installed in
      numerous locations throughout the network to provide regeneration of
      optical signals. This equipment, known as opto-electrical regenerators,
      essentially converts optical signals into electrical signals which are
      then amplified and converted back to optical signals allowing them to
      travel longer distances.

                                       33
<PAGE>
      This technology is expensive to deploy, difficult to maintain and
      inefficient. Advances in optical amplification component technology now
      make it possible to transmit an optical signal over a longer distance
      without opto-electrical conversion by using modules known as erbium-doped
      fiber amplifiers, or EDFAs, and Raman amplifiers. EDFAs combine a section
      of fiber with traces of an element which excites light signals as they
      pass through, resulting in the amplification of the signal. Unlike EDFAs,
      Raman amplifiers use the transmission fiber itself for amplification and
      do not require any specialty fiber.

    - DENSE WAVELENGTH DIVISION MULTIPLEXING.  Due to the increased demand for
      bandwidth capacity, communication equipment suppliers are developing
      optical systems that allow more data to be transmitted over an existing
      fiber without the addition of new fiber. This is being accomplished
      through components that utilize wavelength division multiplexing
      technology, or WDM, which simultaneously transmits multiple wavelengths
      instead of just one wavelength over a single fiber. Optical signals
      traveling over different wavelengths are consolidated using multiplexing
      devices at one end, then transmitted over a single fiber. At the other end
      of the fiber the optical signal is demultiplexed, or separated, much like
      a prism separating different colors of light. This technology has been
      further enhanced by the introduction of dense wavelength division
      multiplexing, or DWDM, which permits wavelengths to be more closely
      spaced, thereby allowing more wavelengths to be transmitted
      simultaneously.

    BANDWIDTH MANAGEMENT.  Bandwidth management technologies enable
communication equipment suppliers to add intelligence to their systems, which
allows communication service providers to monitor the performance, and control
the direction, of light signals throughout the optical network.

    - WAVELENGTH MONITORING.  As fiber optic networks become more complex,
      wavelength monitoring is critical to maintaining a high quality of
      service. Currently, optical signals are transmitted over a limited number
      of wavelengths. While adding more wavelengths in a single optical fiber
      can significantly increase the network capacity, managing a large and
      increasing number of wavelengths on optical fibers poses a constant
      challenge to the communication service providers. These monitoring issues
      can be resolved by integrating optical components with electronics,
      providing intelligence to fiber optic systems. The added intelligence to
      the network enables communication service providers to make decisions that
      improve traffic flow and network efficiency.

    - OPTICAL SWITCHING.  Today's optical networks are simple point-to-point
      transmission systems in which switching, or changing the direction of an
      optical signal, is performed electronically rather than optically. As
      networks grow more complex towards all optical systems, there is a growing
      demand for fiber optic components that can switch without an
      opto-electrical conversion.

SEGMENTATION OF THE COMMUNICATIONS NETWORK

    Communication service providers rely upon communication equipment suppliers
to provide systems that address the specific technical, pricing and performance
requirements of their networks. Network requirements will differ throughout the
various segments of a network, therefore systems from different equipment
suppliers are often installed. Optical component manufacturers provide the
underlying technologies for these systems. The four segments of the network
include:

    - ultra-long haul, for cross-country connections;

    - long haul, for long distance connections between cities;

    - metropolitan, for connections within urban areas; and

    - access, for connections to individual homes and businesses.

                                       34
<PAGE>
    The ultra-long haul and long haul network segments currently represent the
largest markets today for optical equipment. Optical technologies in the
metropolitan and access network segments are becoming increasingly prevalent.

CHALLENGES FACED BY FIBER OPTIC COMPONENT MANUFACTURERS

    Communication equipment suppliers rely upon fiber optic component
manufacturers to quickly design, manufacture and supply advanced optical
technologies. Even large communication equipment suppliers that manufacture
their own components are finding that demand for components exceeds their own
supply capabilities and are increasingly seeking third-party providers to
supplement their supply. Component manufacturers face the following issues in
trying to meet this demand.

    - NEED FOR OPTICAL COMPONENT INTEGRATION.  Communication equipment suppliers
      strive to reduce the overall cost, size, amount and manufacturing
      complexity of equipment used to build optical networks. The number of
      components that they must utilize to improve system performance has
      substantially increased due to the growing complexity of optical network
      systems. Thus, component manufacturers need to integrate more optical
      components into single compact modules. Such integrated components may
      often provide higher performance and functionality than individual
      products that are linked together, however, integration often adds more
      design complexity.

    - NEED FOR OPTICAL COMPONENT MANUFACTURING CAPACITY.  Rapid technological
      advances coupled with high demand for the latest optical components and
      integrated optical modules has reduced product lifecycles and shortened
      the time for deployment within networks. Optical component manufacturers
      are increasingly compelled to achieve a significant ramp-up in
      manufacturing capacity and reduce time-to-market for new component design
      in order to meet the demand of equipment suppliers.

    - NEED FOR OPTICAL COMPONENT QUALITY AND RELIABILITY.  While end users are
      demanding more bandwidth for voice and data services, they are typically
      unwilling to accept service levels that are below that which they have
      grown accustomed to with traditional voice service. Managing high volumes
      of voice and data traffic utilizing early-stage optical technology poses a
      unique problem to communication service providers that face the threat of
      significant revenue loss and customer churn if they do not provide a high
      level of service quality. Component manufacturers are increasingly
      expected to enhance and grow their technical expertise to achieve product
      quality and reliability that meets or exceeds technical standards.

    - NEED FOR A BROAD LINE OF COMPONENTS AND EXPERTISE.  As the complexity of
      optical networks increases, their performance can be enhanced by
      integrating more optical components into network equipment. Equipment
      suppliers prefer to rely on optical component manufacturers that possess
      technical expertise and knowledge across a broad range of components, and
      are able to efficiently integrate multiple component types into a custom
      solution. In addition, equipment suppliers that seek to streamline vendor
      qualification procedures and concentrate volume purchases may choose to
      use fewer component providers.

THE OPLINK SOLUTIONS

    We provide a broad line of high performance fiber optic components and
integrated optical modules worldwide to communication equipment suppliers.
Through internal research and development and selective acquisitions we have
developed over 20 types of primary components which can be integrated through
various combinations to create over 100 custom solutions. For all segments of
the network we provide our customers with high quality passive components and
integrated optical modules that are used for bandwidth creation and management.
In situations where a customer requires a combination of multiple components
within a module, our highly trained engineering and marketing

                                       35
<PAGE>
staff works closely with them to design a reliable integrated solution. We work
with our customers early in their development cycle and design our products to
meet their particular requirements. This provides us with the ability to capture
the volume production requirements of our customers when their systems are ready
for commercial deployment. We support our customers' volume and time-to-market
requirements with advanced micro-optic manufacturing and packaging facilities in
both the United States and China.

THE OPLINK STRATEGY

    Our objective is to be a leading supplier of high performance fiber optic
components and integrated optical modules. The key elements of this strategy
include:

    EXPAND OUR MANUFACTURING CAPACITY AND ENHANCE MANUFACTURING CAPABILITIES
THROUGH AUTOMATION.  We plan to aggressively increase our manufacturing capacity
in San Jose, California and Zhuhai, China. In addition, we intend to continue to
invest in our manufacturing process and introduce automation techniques. We
believe this will increase process yield, throughput and quality.

    BUILD NEW AND EXPAND EXISTING CUSTOMER RELATIONSHIPS.  Our experienced staff
of engineers work closely with our customers early in the product development
cycle to customize our products, or create new products, to meet our customers'
specific needs. This close involvement with our customers can extend for many
months, and in the process our staff gains in depth knowledge about our
customers' special requirements. This knowledge helps us respond more
effectively with solutions to the challenges our customers face. Through these
activities, we have built relationships with premier communication equipment
suppliers, including: ADVA International, Cisco, Corning, JDS Uniphase, Lucent,
LuxN and Sycamore. To better serve our existing customer base and attract new
customers, we intend to significantly increase our technical marketing and
support teams.

    EXPAND AND ENHANCE OUR EXISTING LINE OF PRODUCTS FOR ALL SEGMENTS OF THE
OPTICAL NETWORK.  Our innovative fiber optic products enable both bandwidth
creation and management. Through internal research and development and selective
acquisitions we have built, and plan to continue to build, a broad product line
of passive fiber optic components and integrated optical modules to meet the
requirements of our customers. By offering a broad array of products we are able
to serve numerous equipment providers across all segments of the network.

    CONTINUE TO DEVELOP OPTICAL PRODUCTS WITH INTELLIGENCE FEATURES.  We believe
that some our products, including our wavelength performance monitors and
wavelength protection modules, are differentiated by their intelligence
features. The intelligence of an optical product is created by adding an
electronic interface which provides monitoring and controlling capabilities to
optical networks. We are currently adding this capability to other products
including our reconfigurable wavelength add/drop and wavelength switching
families of products. We plan to continue to enhance existing and introduce new
intelligent optical modules to our product line within the bandwidth management
segment of our business. We believe that this will allow us to capitalize on the
industry trend towards all-optical networks and enhanced network functionality.

    CONTINUE TO ATTRACT TALENTED PERSONNEL.  We intend to continue recruiting
highly-qualified personnel at our design and manufacturing centers in San Jose,
California and China. We believe that the combination of our local knowledge and
the availability of experienced personnel in China are a competitive advantage
that will help us to meet the growth of our business and respond more quickly to
large volume orders.

    PURSUE STRATEGIC ACQUISITIONS OF BUSINESSES AND TECHNOLOGIES.  We intend to
pursue strategic acquisitions of businesses and technologies that can provide us
with key intellectual property, strategic

                                       36
<PAGE>
products and highly-qualified engineering personnel to rapidly increase our
technological expertise and expand the breadth of our product portfolio.

PRODUCTS AND TECHNOLOGIES

    We provide a broad line of fiber optic components and integrated optical
modules designed to satisfy the needs of communication equipment suppliers. We
categorize our products by the functionalities provided within a network, from
bandwidth creation to bandwidth management. Some of our products have attributes
which combine both of these functions. While all of our bandwidth creation
components can be categorized as passive optical components, some of our
bandwidth management components utilize electronic interfaces to provide
intelligence and to enhance their function in a network.

BANDWIDTH CREATION PRODUCTS

    Communication equipment suppliers use our bandwidth creation products to
expand the capacity of their customers' networks and enable optical signals to
travel over greater distances.

    WAVELENGTH EXPANSION PRODUCTS.  In fiber optic communications, different
signals are transmitted over multiple wavelengths. With increases in the number
of wavelengths and data rates, spacing between the wavelengths narrows and it
becomes increasingly important to separate and direct them into their respective
receivers. We offer wavelength expansion products that function as highly
sensitive filters that enable combination and separation of a particular
wavelength. Wavelength expansion products include wavelength multiplexing
(combining), de-multiplexing (separating), wavelength interleaving, which
combines light signals from two or more simultaneous sources over a single
fiber, and locking, which prevents wavelengths traveling simultaneously over the
same fiber from interfering with one another. We offer the following products to
handle these tasks.

    - DENSE WAVELENGTH DIVISION MULTIPLEXERS.  A dense wavelength division
      multiplexer, or DWDM, is an integrated optical module that combines two or
      more wavelengths for transmission over a single fiber (multiplexing) or
      separates these wavelengths (demultiplexing) at the receiving end. Our
      DWDM technology uses thin film filter technology to separate optical
      signals.

    - DWDM INTERLEAVERS.  A DWDM interleaver is an optical component that
      combines light signals from two or more simultaneous sources over a single
      fiber, which effectively doubles the capacity of the optical network
      system, or separates a single light source into multiple signals.

    - WAVELENGTH LOCKERS.  A wavelength locker is an opto-electrical component
      that is used to stabilize the wavelengths of lasers used in DWDM
      transmission systems. Wavelength lockers ensure that the wavelength of a
      source laser does not interfere with an adjacent wavelength signal.

    - NOISE REDUCTION FILTERS.  A noise reduction filter is a filter array
      module used in conjunction with a particular DWDM module to reduce
      undesired signals in a communications transmission.

    - CHROMATIC DISPERSION COMPENSATORS.  A chromatic dispersion compensator is
      a module that reduces the negative effect of different wavelengths
      reaching their destinations at different times.

    - DISPERSION SLOPE COMPENSATORS.  A dispersion slope compensator is a module
      that reduces the negative effect of different wavelengths reaching their
      destinations at different times in an irregular fashion.

    OPTICAL AMPLIFICATION PRODUCTS.  Optical fiber amplifiers are widely
deployed in optical communication networks to enhance the optical signal power.
Optical signals typically lose power and eventually are lost after travelling a
long distance along an optical fiber. This power loss is referred to as
attenuation. Through recent advances in technology, the optical signal can be
amplified with EDFAs

                                       37
<PAGE>
or with Raman amplifiers, neither of which require opto-electrical conversion.
The amplifiers are arranged along fiber cable lines at regular intervals to
enable the optical signal to reach its destination as a clear and readable
message. While amplifiers range in complexity, a typical amplifier consists of a
fiber and several of the components listed below.

    - ISOLATORS.  Isolators are fiber optic devices that transmit light in only
      one direction, thus preventing reflected light signals from returning to
      its laser source. Reflected light can interfere with a laser's process and
      create noise, which can impair system performance in optical networks.

    - TAP COUPLERS.  Tap couplers transfer optical signals between fibers. They
      are widely used for system monitoring purposes and have very low insertion
      loss, or the power loss incurred when adding additional components to a
      fiber cable.

    - WDM PUMP/SIGNAL COMBINERS.  Micro-optic WDM pump/signal combiners are
      components that provide power for the optical amplifier. They are used to
      efficiently combine light signals with pump laser sources. Pump lasers are
      active optical components used in optical amplifiers such as EDFAs, or
      erbium-doped fiber amplifiers, to amplify or regenerate light signals that
      naturally suffer loss while traveling over distance within an optical
      network.

    - INTEGRATED HYBRID COMPONENTS.  Optical amplifier systems can combine
      optical components, including isolators, tap couplers and WDM pump/signal
      combiners. The main advantage of hybrid components is that they minimize
      the amplifier package size and reduce manufacturing cost.

    - GAIN FLATTENING FILTERS.  Gain flattening filters are used to ensure
      signals are amplified by equal amounts. Our thin film filter technology,
      or the technology in which layers of thin film separate optical signals,
      employs multiple layers of optical materials on glass to adjust optical
      output at different wavelengths to meet the needs of next-generation high
      power amplifiers.

    - WDM PUMP COMBINERS.  WDM pump combiners are used to increase the power of
      an optical amplifier by combining multiple pump lasers into one common
      pump source for amplification.

    - POLARIZATION BEAM COMBINERS.  Polarization beam combiners are optical
      components that combine two of the same or different wavelengths with
      opposing polarization to increase the power output of the optical
      amplifier.

    - VARIABLE OPTICAL ATTENUATORS.  Variable optical attenuators, or VOAs, are
      optical devices that reduce the power of the optical signal in DWDM
      networks to ensure that all optical signals within a network have equal
      power. The amount of power reduction of a particular optical signal can be
      adjusted to match the power of other optical signals in the network.

BANDWIDTH MANAGEMENT PRODUCTS

    Communication equipment suppliers use our bandwidth management products to
add intelligence to their systems which allows communication service providers
to monitor the performance, and control the direction, of light signals
throughout the optical network.

    WAVELENGTH PERFORMANCE MONITORING AND PROTECTION PRODUCTS.  The ability to
monitor wavelengths within an optical network enables service providers to
maintain quality of service even in the event of an interruption in the signal
path, such as a cut in the fiber. It is significantly more difficult to monitor
signal flow in optical systems as compared to electrical systems. Monitoring
requires that optical signals be extracted from the fiber without interfering
with the optical signal travelling through the same fiber. We offer products
that enable service providers to monitor network performance and make necessary
decisions for traffic flow and network efficiency.

                                       38
<PAGE>
    - SUPERVISORY CHANNEL MONITORS.  Our supervisory channel monitors are
      integrated solutions that combine multiple network performance monitoring
      functions in a single package and integrate our WDMs and couplers. These
      modules enable communication service providers to identify line
      connectivity.

    - WAVELENGTH PERFORMANCE MONITORS.  Our multi-channel wavelength performance
      monitors are integrated solutions that convert light signals into
      electrical signals through a combination of tap couplers; splitters, a
      passive device that separates light signals; and third-party
      photodetectors, a device supplied by another optical component
      manufacturer that receives a light signal in an optical network and
      converts it into an electrical signal. These modules allow communication
      service providers to monitor whether or not wavelengths are being
      transmitted properly through the network.

    - WAVELENGTH PROTECTION MODULES.  Our multi-channel wavelength protection
      modules are integrated solutions that combine tap couplers, splitters,
      switches and third-party photodetectors. These modules integrate network
      protection functions and monitor the optical signal quality, such as
      optical power, wavelength and signal-to-noise ratio. In addition, these
      modules can provide fast routing and switching capabilities in response to
      unexpected errors in the optical network. They also enable communication
      service providers to instantly monitor the network performance at each
      individual optical wavelength, allowing increased management of traffic
      flow and network efficiency.

    OPTICAL SWITCHING PRODUCTS.  As optical networks become more complex, there
is an increasing demand to provide switching capability to direct optical
signals across multiple points in the network. We supply optical fiber switching
products that provide all-optical signal switching between fibers with up to
eight different end destinations.

    - SWITCHES.  Optical switches are devices that can direct optical signals to
      different end destinations.

    - OPTICAL ADD/DROP MULTIPLEXERS.  Optical add/drop multiplexers, or OADMs,
      are used when part of the information from an optical signal carried on
      the network is demultiplexed, or dropped, at an intermediate point and
      different information is multiplexed, or added, for subsequent
      transmission. The remaining traffic passes through the multiplexer without
      additional processing. The OADM is typically used for rerouting a number
      of specific optical wavelengths with different end destinations.

    - RECONFIGURABLE OADMS.  Reconfigurable OADMs combine OADM functionality
      with optical switches and add flexibility to the network by allowing the
      dynamic add/drop of variable optical wavelengths with different end
      destinations.

    - CIRCULATORS.  Circulators consist of sophisticated micro-optic components
      that are used to direct optical signals between different fibers.
      Circulators are also used in optical amplifying applications.

CUSTOMERS

    We sell our products worldwide to communication equipment suppliers. In
certain cases, we sell our products to other component manufacturers for resale.
During the year ended June 30, 2000, we sold our products to over 100 companies
worldwide.

    During the year ended June 30, 2000, sales to Lucent, Sycamore Networks and
JDS Uniphase accounted for 42.6%, 15.7% and 10.6% of revenue. We expect that the
majority of our revenues will continue to depend on sales to a small number of
customers. In addition, some of our customers are companies with which we
presently compete or in the future may compete.

CUSTOMER CASE STUDIES

    We work closely with our customers to meet their unique needs. The following
are examples of successful collaborations with our customers to develop
innovative products.

    - We worked closely with one of our major customers to quickly develop a
      solution enabling them to monitor and protect signals in their DWDM
      systems. The customer required a module that could tap into the network
      with minimal intrusion, monitor wavelengths in an optical signal and, in
      the case of signal loss, perform fiber switching to reroute the signal.
      All of these functions had to be packed in a very small box. We quickly
      developed a custom solution by integrating numerous components into a
      module which met the customer's specifications. This integrated product
      provides on-time signal monitoring by contemporaneously analyzing
      wavelength, power level and signal-to-noise ratio information. It also
      performs network protection functions in less than 15 milliseconds, which
      exceeds the industry standard of 50 milliseconds.

    - A global communication equipment supplier planned to increase the speed of
      their networking systems by migrating from copper to optical technology.
      Because they did not have the optical expertise to achieve this migration,
      they relied upon our technical experts to design and consult on the
      technology. We worked closely with the customer to create a product that
      could seamlessly be integrated with the customer's existing system. The
      customer was among the first few companies to launch next-generation metro
      DWDM systems. Our contributions help to shorten their time-to-market. As a
      result, we have become one of their major suppliers of DWDM and other
      fiber optic components.

CUSTOMER AGREEMENTS

    In July 1999, we entered into an agreement with Corning providing that we
will purchase all of our external requirements for various materials from
Corning as long as Corning offers the materials to us on terms at least as
favorable as those offered to us by another supplier. Corning has agreed to
purchase various components from us and we will offer to supply Corning any
quantity of various components that is within our manufacturing capacity so long
as Corning purchases a minimum value of components from us each year. In
addition, if, prior to April 1, 2002, Corning requests a license to one or more
of our patents that were applied for or granted before April 1, 1999, we have
agreed to negotiate in good faith with Corning to enter into this license. The
agreement terminates on January 1, 2004, unless we and Corning agree to extend
it.

    In July 1999 and November 1999, we entered into three consignment supply
agreements with Lucent Technologies pursuant to which we agreed to sell Lucent
various modules on a blanket order consignment basis. The agreements provide
that Lucent will notify us periodically of the number of modules it will require
us to ship on consignment. Lucent has agreed to purchase any modules it
withdraws from the consigned inventory at an agreed price. To the extent we
offer to sell modules that are similar in quality and volume to any other
customer at a lower price, we have agreed to offer

                                       41
<PAGE>
Lucent the lower price. Lucent may terminate any or all consignment orders, in
whole or in part, at any time and without cause.

BACKLOG

    We define backlog to include orders for which we expect to recognize revenue
within the succeeding twelve months. As of June 30, 2000, our backlog was
$54.6 million. Sales are made pursuant to purchase orders, which are frequently
subject to revision or cancellation. Because of the possibility of changes in
delivery or acceptance schedules, cancellations of orders, distributor returns
or price reductions, our backlog, as of any particular date, may not be
representative of actual sales for any succeeding period.

MARKETING, SALES AND CUSTOMER SUPPORT


    We market and sell our products through both direct sales and distribution
channels, including three domestic and 13 international sales representatives
and distributors. Our sales representatives and distributors are independent
organizations that generally have exclusive geographic territories within North
America, Europe and Asia. As of July 31, 2000, we employed 18 people in sales,
marketing and customer service and support who manage key customer accounts and
support our direct sales force, representatives and distributors.


    Our marketing team promotes our products within the communications industry
as well as gathers and analyzes market research. Our marketing professionals
help us to identify and define next-generation products by working closely with
our customers and our research and development engineers. They also coordinate
our participation in trade shows and design and implement our advertising
effort.

PRODUCT DEVELOPMENT


    As of July 31, 2000, we had 36 engineers, 12 of whom hold Ph.D. degrees, and
123 technicians and operators, involved in research and development of our
products. Our engineering team has extensive design, package, processing and
software experience in the fields of fiber optic components, integrated optic
interfaces and systems. To date, we have been granted 10 patents by, and have 22
patent applications pending with, the U.S. Patent and Trademark Office for
various technologies and products, including DWDM interleavers, DWDM modules,
multi-channel optic filter arrays, high reliability fused couplers, circulators,
compact optical switches and polarization beam combiners.


    Our primary product development center is located in San Jose, California.
We also maintain product development centers in Zhuhai and Fuzhou, China. Our
research and development expense was $3.7 million, $626,000 and $455,000 for the
years ended June 30, 2000, 1999 and 1998, respectively. We have increased, and
intend to continue to increase, our research and development budget and staff to
enhance our current fiber optic components and modules, and to develop new
technologies and products to serve the next-generation communication markets.

MANUFACTURING

    We currently manufacture the majority of our components and modules at our
headquarters in San Jose, California. We also manufacture our products at our
manufacturing facilities in Zhuhai and Fuzhou, China.

    Each of our facilities maintain complete in-house manufacturing capabilities
including component and module design, integration, production and testing. We
plan to continue to invest resources in manufacturing management, engineering
and quality control. We also plan to continue to develop

                                       42
<PAGE>
automated manufacturing systems to provide higher throughput, improve yields and
reduce our manufacturing costs.

    We have recently increased our manufacturing capacity by expanding the size
of our San Jose facility from approximately 25,000 square feet to approximately
100,000 square feet. In addition, we are expanding our manufacturing facilities
in Zhuhai from approximately 30,000 square feet to approximately 110,000 square
feet. The component and module designs, assembly procedures, manufacturing
processes and quality standards from our U.S. headquarters are substantially
replicated at our China facilities, and all of the tests are specified to meet
strict industry quality standards.

    A number of critical raw materials used in manufacturing our products are
acquired from single or limited source suppliers. The inability to obtain
sufficient quantities of those materials may result in delays, increased costs
and reductions in our product shipments. Between January 1997 and August 1999,
we entered into several development agreements with Barr Associates, Inc.
pursuant to which we paid Barr to design, develop and build multiple vacuum
deposition systems for us. These systems are used to produce bandpass filters,
an integral component of our DWDMs. Under the terms of these agreements, we are
entitled to purchase 100% of the bandpass filters produced by Barr on these
systems at a discount. Our discount will continue until our accumulated total
discount on filters produced in all systems equals the total amount of our
payment for the design, development and cost to build the systems.

QUALITY

    We have established a quality management system to assure that the products
we provide to our customers meet or exceed industry standards. This system is
based on the international standard ISO 9001. Our U.S. headquarters have been
ISO 9001 certified in research and manufacturing since July 1998. Our Zhuhai
facility has been ISO 9002 certified in manufacturing since January 2000.

COMPETITION

    The markets in which we sell our products are highly competitive. Our
overall competitive position depends upon a number of factors, including:

    - price;

    - availability, performance and reliability of our products;

    - the breadth of our product line;

    - the ability to win designs through prototyping;

    - manufacturing capacity;

    - the quality of our manufacturing processes;

    - the compatibility of our products with existing communications networks;
      and

    - our ability to participate in the growth of emerging technologies.

    We believe that our principal competitors are the major manufacturers of
optical components and modules, including both vendors selling to third parties
and business divisions within communication equipment suppliers. Our principal
competitors in the components market include Avanex Corporation, Ciena
Corporation, Corning, DiCon Fiberoptics, Furukawa Electrical, Lucent, New Focus,
Nortel, Sumitomo, Tyco Electronics and JDS Uniphase, which recently acquired
E-TEK Dynamics and announced its intended acquisition of SDL. We believe that we
primarily compete with diversified suppliers, such as Corning, JDS Uniphase,
Lucent and Nortel, for the majority of our product line and to a lesser extent
with niche players that offer a more limited product line.

                                       43
<PAGE>
    Many of these companies have substantially greater financial, engineering
and manufacturing resources as well as greater name recognition and stronger
customer relationships. Some of our customers are companies with which we
presently compete or in the future may compete. In addition, some of our
customers have been or could be acquired by, or enter into strategic relations
with, our competitors. We anticipate that further consolidation will occur in
our industry, thereby possibly increasing competition in our target markets.

INTELLECTUAL PROPERTY

    To date, we have been granted 10 patents by, and have 22 patent applications
pending with, the U.S. Patent and Trademark Office covering various technologies
and products. While we rely on patent, copyright, trade secret and trademark law
and restrictions on disclosure to protect our technology, we believe that
factors such as the technological and creative skills of our personnel, new
product developments, frequent product enhancements and reliable product
maintenance are essential to establishing and maintaining a technology
leadership position. We cannot assure you that others will not develop
technologies that are similar or superior to our technology.

    Protecting our intellectual property is critical to the success of our
business. Despite our efforts to protect our proprietary rights, various
unauthorized parties may attempt to copy or otherwise obtain and use our
products or technology. Policing unauthorized use of our products is difficult,
and there can be no assurance that the steps taken by us will prevent
misappropriation of our technology. Moreover, the laws of some foreign
countries, including China, do not protect our proprietary rights as fully as in
the United States.

    Substantial litigation regarding intellectual property rights exists in the
optical communications industry. We expect that fiber optic components and
modules may be increasingly subject to third-party infringement claims as the
number of competitors in our industry segments grows and the functionality of
products in different industry segments overlaps. In addition, we believe that
many of our competitors in the optical communications industry have filed or
intend to file patent applications covering aspects of their technology on which
they may claim our technology infringes. We are currently involved in patent
infringement actions with E-TEK Dynamics and Chorum Technologies. For a
description of these actions, see "--Legal Proceedings and Regulatory Matters."
We cannot make any assurances that other third parties will not claim
infringement by us with respect to our technology. Any such claims, with or
without merit, could be time-consuming to defend, result in costly litigation,
divert management's attention and resources, cause product shipment delays or
require us to enter into royalty or licensing agreements. Such royalty or
licensing agreements, if required, may not be available on terms acceptable to
us, if at all. A successful claim of product infringement against us and failure
or inability by us to license the infringed or similar technology could
seriously harm our financial condition.

EMPLOYEES


    As of July 31, 2000, we had 648 full-time employees located in the United
States, 159 of whom were engaged in product development, 358 in manufacturing,
26 in quality, 18 in sales, marketing, application support and customer service,
and 37 in general and administration. As of July 31, 2000, we had 804 full-time
employees located in China, five of whom were engaged in product development,
735 in manufacturing, 33 in quality, and 31 in general and administration. None
of our employees are represented by a labor union. We have not experienced any
work stoppages and we consider our relations with our employees to be good.

FACILITIES

    In the United States, we lease a total of approximately 122,380 square feet
in four buildings located in San Jose, California. Of the 122,380 square feet:

    - we lease a 62,000 square foot manufacturing facility and 16,000 square
      feet of administrative, sales and marketing space pursuant to a lease that
      expires in February 2005;

    - we lease a 38,000 square foot research and development facility pursuant
      to a lease that expires in October 2002; and

    - we lease a 6,380 square foot filter coating facility pursuant to a lease
      that expires in July 2005.

    In China, we lease a total of approximately 140,000 square feet in two
facilities located in Zhuhai and Fuzhou, China. Our Zhuhai facilities total
approximately 130,000 square feet, with the manufacturing facility totaling
approximately 110,000 square feet and 20,000 square feet of office and dormitory
space. The lease for these facilities expires in March 2005. In Fuzhou we
maintain an approximately 10,000 square foot research and development and
manufacturing facility pursuant to a lease expiring on August 2007. In addition,
in May 2000, we acquired rights to a parcel of land in China which we intend to
use for future expansion of our manufacturing facilities. We have the right to
use this land until May 2050.

LEGAL PROCEEDINGS AND REGULATORY MATTERS

LEGAL PROCEEDINGS

    On November 12, 1999, E-TEK Dynamics, Inc., recently acquired by JDS
Uniphase, filed a lawsuit against us, in the United States District Court for
the Northern District of California (Case No. C99-04921 CRB) alleging that we
have infringed E-TEK's U.S. Patent No. 5,652,814 relating to fiber optic
couplers based on our manufacture and sale of our DWDM products. E-TEK is
seeking an award for unspecified damages, including treble damages, for
intentional and willful infringement, contributory infringement, inducement to
infringe, and injunctive relief. Our DWDM products generated a majority of our
revenues for the year ended June 30, 2000. An adverse ruling in this matter
would materially adversely affect our financial condition. We are defending
ourselves vigorously in this lawsuit.

    On June 16, 2000, Chorum Technologies, Inc. filed a complaint, C.A.
No. 3-00CV0458-M, against us and our subsidiary, Telelight Communications Inc.,
in the U.S. District Court for the Northern District of Texas (Dallas Division).
In the complaint Chorum alleges that we have infringed two U.S. patents
allegedly owned by Chorum relating to fiber optical interleaving, based on our
manufacture of and offer to sell various products including the CFOI-100 series
of fiber optical interleavers. Chorum also alleges that our use of the name
"TrueSlicer" in connection with the public announcement of the CFOI-100 products
is confusingly similar to Chorum's alleged "Slicer" and "Optical Slicer" marks,
and therefore violates section 43(a) of the Lanham Act and various unspecified
Texas state laws. Chorum seeks actual and enhanced damages, injunctive relief,
costs and attorney fees, and other relief. We have not yet responded to the
complaint, but intend to defend ourselves vigorously.

    The outcomes of the foregoing lawsuits are inherently uncertain. Our defense
of these lawsuits, regardless of their eventual outcomes, will likely be costly
and time consuming and will divert the efforts and attention of our management
and technical personnel. Patent litigation is highly complex and can extend for
a protracted period of time, which can substantially increase the cost of
litigation. Accordingly, the expenses and diversion of resources associated with
either of these matters could seriously harm our business and financial
condition. In the event of an adverse ruling in either matter:

    - we may be liable for significant monetary damages;

                                       45
<PAGE>
    - we may be enjoined from manufacturing, selling or offering to sell certain
      of our products, including, in respect of the E-TEK litigation, products
      that are currently generating a majority of our revenues, and products we
      are developing; and

    - we may have to engage in a redesign of these products and products we are
      developing.

    If an injunction were granted that prevents us from selling these products,
we may have to seek a license to continue to sell and offer these products and
products we are developing. We may not be able to secure any license on
commercially reasonable terms, if at all. If we were to settle any of the
foregoing matters and secure a license to continue to sell and offer our
products and those we are developing, the licensing fees could be substantial. A
redesign of our products would result in an interruption in sales that could
extend for some time. We do not have insurance that would indemnify us for any
liability that may be imposed in connection with the legal actions described
above. Accordingly, if any of the foregoing events occur, it could result in a
substantial reduction in our revenue and could result in losses over an extended
period of time, which would have a material adverse effect on our results of
operations.

REGULATORY MATTERS

    Our products are subject to U.S. export control laws and regulations that
regulate the export of products and disclosure of technical information to
foreign countries and citizens. These laws and regulations may require licenses
for the export of some of our products to, and disclosure of our technology in,
some countries, including China, and disclosure of our technology to a number of
our employees who are foreign citizens. We plan to file an application shortly
to obtain a commodity classification confirming that we may export our products
and disclose our technology to foreign countries, and citizens, without export
licenses. In the event this classification is not obtained, we have
alternatively filed applications to obtain licenses permitting us to disclose
our technology to specified employees. However, we cannot assure you that we
will obtain these classification and licenses. Furthermore, the Department of
Commerce has initiated an inquiry as to whether one of our employees received
information in violation of licensing requirements. While we do not believe that
the results of this inquiry will materially harm our business, we may be found
to have violated export restrictions with respect to this individual and other
individuals, which could result in criminal, civil and administrative penalties,
including the denial of export privileges.

SCIENTIFIC ADVISORY BOARD

    We have established a Scientific Advisory Board to provide specific
expertise in areas of research and development relevant to our business. The
Scientific Advisory Board meets periodically with our technical and development
personnel and management to discuss our present and long-term research and
development activities. Scientific Advisory Board members include:

BOARD OF DIRECTORS

    Our board of directors currently consists of seven members. Upon the closing
of this offering, the terms of office of the board of directors will be divided
into three classes. As a result, a portion of our

                                       49
<PAGE>
board of directors will be elected each year. The division of the three classes,
the initial directors and their respective election dates will be as follows:

    - the class I directors will be Ian Jenks and David Spreng, and their term
      will expire at the annual meeting of stockholders to be held in 2001;

    - the class II directors will be Chieh Chang and Herbert Chang, and their
      term will expire at the annual meeting of stockholders to be held in 2002;
      and

    - the class III directors will be Joseph Y. Liu, Terence P. Brown and
      Leonard J. LeBlanc, and their term will expire at the annual meeting of
      stockholders to be held in 2003.

    At each annual meeting of stockholders after the initial classification, the
successors to directors whose terms will then expire, will be elected to serve
from the time of election and qualification until the third annual meeting
following their election. In addition, our certificate of incorporation will
provide that the authorized number of directors may be changed only by
resolution of the board of directors. Any additional directorships resulting
from an increase in the number of directors will be distributed among the three
classes so that, as nearly as possible, each class will consist of one-third of
the directors. This classification of the board of directors may have the effect
of delaying or preventing changes in our control or management.

BOARD COMMITTEES

    COMPENSATION COMMITTEE.  We established a compensation committee in July
1999. The compensation committee currently consists of Messrs. Ian Jenks,
Herbert Chang and David Spreng. The compensation committee reviews and
recommends to the board of directors the compensation of all of our officers and
directors, including stock compensation and loans, and establishes and reviews
general policies relating to the compensation and benefits of our employees.

    AUDIT COMMITTEE.  We established an audit committee in July 1999. The audit
committee currently consists of Messrs. Herbert Chang, Terence P. Brown, and
Leonard LeBlanc. The audit committee reviews our internal accounting procedures
and consults with and reviews the services provided by our independent
accountants.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

    None of the current members of our compensation committee is now or has ever
been one of our officers or employees. None of our executive officers currently
serves, or in the past has served, as a member of the board of directors or
compensation committee of any entity that has one or more executive officers
serving on our board or compensation committee. Prior to the formation of the
compensation committee, compensation decisions were made by our entire board of
directors.

DIRECTOR COMPENSATION

    We do not currently compensate our directors in cash for their service as
members of the board of directors, although directors are eligible to be
reimbursed for expenses incurred in connection with attending board of directors
and committee meetings. During fiscal 2000, we granted an option to purchase
400,000 shares of our common stock to Ian Jenks and an option to purchase
100,000 shares of our common stock to David Spreng, each at an exercise price of
$2.50 per share. Each of these options vests 25% of the shares after one year
and the remainder of the shares on a monthly basis over the next three years.
Our 2000 Equity Incentive Plan also provides for the automatic grant of
non-statutory stock options to nonemployee directors. For further information
regarding the provisions of the 2000 Equity Incentive Plan, see "--Employee and
Director Benefit Plans."

                                       50

LIMITATIONS ON DIRECTORS' LIABILITY AND INDEMNIFICATION

    Our certificate of incorporation and bylaws provide that we will indemnify
our directors and officers and may indemnify our employees and other agents to
the fullest extent permitted by law. Delaware law provides that directors of a
corporation will not be personally liable for monetary damages for breach of
their fiduciary duties as directors, except liability for:

    - any breach of their duty of loyalty to the corporation or its
      stockholders;

    - acts or omissions not in good faith or that involve intentional misconduct
      or a knowing violation of law;

    - unlawful payments of dividends or unlawful stock repurchases or
      redemptions; or

    - any transaction from which the director derived an improper personal
      benefit.

The limitation of liability does not apply to liabilities arising under the
federal securities laws and does not affect the availability of equitable
remedies such as injunctive relief or rescission.

    We believe that indemnification under our bylaws covers at least negligence
on the part of indemnified parties. Our bylaws also permit us to secure
insurance on behalf of any officer, director, employee or other agent for any
liability arising out of his or her actions in their capacity as an officer,
director, employee or other agent, regardless of whether the bylaws would permit
indemnification.

    We intend to enter into agreements to indemnify our directors and executive
officers prior to completing this offering, in addition to the indemnification
provided for in our bylaws. These agreements, among other things, will provide
for indemnification for judgments, fines, settlement amounts and expenses,
including attorneys' fees incurred by the director, or executive officer in any
action or proceeding, including any action by or in our right, arising out of
the person's services as a director or executive officer, any of our
subsidiaries or any other company or enterprise to which the person provides
services at our request. We believe that these provisions and agreements are
necessary to attract and retain qualified persons as directors and executive
officers.

    The limitation on liability and indemnification provisions in our
certificate of incorporation and bylaws may discourage stockholders from
bringing a lawsuit against our directors for breach of their fiduciary duty and
may reduce the likelihood of derivative litigation against our directors and
officers, even though a derivative action, if successful, might otherwise
benefit us and our stockholders. A stockholder's investment in us may be
adversely affected to the extent we pay the costs of settlement or damage awards
against our directors and officers under these indemnification provisions.

    At present, there is no pending litigation or proceeding involving any of
our directors, officers or employees in which indemnification is sought, nor are
we aware of any threatened litigation that may result in claims for
indemnification.

EXECUTIVE COMPENSATION

    The following table presents the compensation earned, awarded or paid for
services rendered to us in all capacities for the fiscal year ended June 30,
2000 by:

    - our Chief Executive Officer;

    - those persons who were, at June 30, 2000, our five other most highly
      compensated executive officers; and

------------------------

(1) The percentage of total options granted is based on an aggregate of
    16,828,800 options granted by us during the fiscal year ended June 30, 2000,
    to our employees.

(2) Options were granted with an exercise price per share equal to the fair
    market value of our common stock on the date of grant, as determined by our
    board of directors.

(3) The potential realizable value is based on the assumption that our common
    stock appreciates at specified annual rates, compounded annually, from the
    date of grant until the expiration of the ten-year term. These numbers are
    calculated based on Securities and Exchange Commission requirements and do
    not reflect our projections or estimates of future stock price growth.
    Potential realizable values are computed by:

       - multiplying the number of shares of common stock underlying each option
         by an assumed initial public offering price of $11.00 per share;

       - assuming that the aggregate stock value derived from that calculation
         compounds at the annual specified rate shown in the table until the
         expiration of the options; and

       - subtracting from that result the aggregate option exercise price.

    Actual gains, if any, on stock option exercises and common stock holdings
    are dependent on the time of such exercise and the future performance of our
    common stock.

    Our 1995 Stock Plan provides for the grant of incentive stock options to
employees, including officers and employee directors, and for the grant of

consultants. The 1995 Stock Plan was adopted by our board of directors and
approved by our stockholders in September 1995.

    As of July 31, 2000, a total of 76,832 shares of our common stock were
available for future grant under the 1995 Stock Plan. This amount includes
amounts returned to the 1995 Stock Plan. The 1995 Stock Plan has 6 million

577,246 shares have been issued and are outstanding as of July 31, 2000 and a
total of 4,385,922 shares have been issued and are outstanding pursuant to the
exercise of options and stock purchase rights granted under the 1995 Stock Plan.

    ADMINISTRATION.  The 1995 Stock Plan is administered by our board of
directors or a committee consisting of our board of directors. The administrator
of our 1995 Stock Plan has the power to determine, among other things:

    - the fair market value of the common stock;

    - the selection of the officers, consultants and employees to whom the
      option and the stock purchase rights may from time to time be granted;

    - whether and to what extent options and stock repurchase rights or any
      combination thereof, are granted under such plan;

    - the number of shares to be covered by each such award granted under such
      plan;

    - the form of agreement for use;

                                       54

      including but not limited to the share price;

    - the terms and restrictions applicable to stock purchase rights and the
      restricted stock purchased by exercising such stock purchase rights; and

    - any other determinations with respect to awards under such plan as the
      administrator deems appropriate.

    OPTIONS.  The exercise price of all incentive stock options granted under
the 1995 Stock Plan must be at least equal to the fair market value of our
common stock on the date of grant. The exercise price of nonstatutory stock
options and stock purchase rights granted under the 1995 Stock Plan must be at
least equal to 85% of the fair market value of our common stock on the date of
grant. With respect to any participant who owns stock representing more than 10%
of the voting power of all classes of our outstanding capital stock, the
exercise price of any incentive stock option granted must be at least equal 110%
of the fair market value on the grant date and the term of the incentive stock
option may not exceed five years. The term of all other options granted under
the 1995 Stock Plan may not exceed 10 years.

    During any fiscal year, incentive stock options exercised by each optionee
may not exceed $100,000, and any excess of such value shall be treated as
nonstatutory stock option.

    Options granted under the 1995 Stock Plan must generally be exercised within
ninety (90) days after the end of the optionee's status as an employee, director
or consultant of ours, within 12 months after the optionee's termination by
death or within 6 months after the optionee's termination by disability, but in
no event later than the expiration of the option's term.

    TRANSFERABILITY OF OPTIONS.  Options and stock purchase rights granted under
the 1995 Stock Plan are generally not transferable by the optionee, and each
option and stock purchase right is exercisable during the lifetime of the
optionee only by the optionee.

    STOCK PURCHASE RIGHTS.  In the case of stock purchase rights, unless the
administrator determines otherwise, the restricted stock purchase agreement
shall grant us a repurchase option exercisable upon the voluntary or involuntary
termination of the purchaser's employment or consulting relationship with us for
any reason, including death or disability. The purchase price for shares
repurchased under the restricted stock purchase agreement shall be the original
price paid by the purchaser and may be paid by cancellation of any indebtedness
of the purchaser to us. The repurchase option shall lapse at a rate determined
by the administrator.

    CHANGES OF CONTROL.  The 1995 Stock Plan provides that in the event of a
change of control of our company, including our merger with or into another
corporation, each outstanding option and stock purchase right shall be assumed
or an equivalent option shall be substituted for by the successor corporation.
If the outstanding options and stock purchase rights are not assumed or
substituted for by the successor corporation, the option will terminate
immediately prior to the consummation of the transaction.

    AMENDMENT AND TERMINATION OF THE 1995 STOCK PLAN.  The board of directors
will have the authority to amend, suspend or terminate the 1995 Stock Plan, as
long as this action does not affect any shares of common stock previously issued
and sold or any option previously granted under the 1995 Stock Plan. Unless
earlier terminated, the 1995 Stock Plan will terminate automatically 10 years
from the date of obtaining stockholder approval of the amended plan in
September 1995. The board has agreed not to make any further grants under the
1995 Stock Option Plan upon the closing of this offering.

2000 EQUITY INCENTIVE PLAN

employees, directors and consultants. These stock awards include incentive stock
options to employees, including officers and employee directors, and
nonstatutory stock options, stock bonuses and stock purchase rights to
employees, directors and consultants. The 2000 Equity Incentive Plan was adopted
by our board of directors in July 2000 and is expected to be approved by our

will take effect on the effective date of the initial public offering.

    ADMINISTRATION.  The 2000 Equity Incentive Plan will be administered by our

directors. The administrator of our 2000 Equity Incentive Plan will have the

    OPTIONS.  The exercise price of all incentive stock options granted under
the 2000 Equity Incentive Plan must be at least equal to the fair market value
of the common stock on the date of grant. The exercise price of nonstatutory
stock options and stock purchase rights granted under the 2000 Equity Incentive
Plan will be determined by the administrator, but must be at least equal to 85%
of the fair market value of our common stock on the date of grant. With respect
to any participant who owns stock representing more than 10% of the voting power
of all classes of our outstanding capital stock, the exercise price of any
incentive stock option granted must be at least equal 110% of the fair market
value on the grant date and the term of the incentive stock option must not
exceed five years. The term of all other options granted under the 2000 Equity
Incentive Plan may not exceed 10 years.

    During any fiscal year, incentive stock options exercised by each optionee
may not exceed $100,000, any excess of such value shall be treated as
nonstatutory stock option.

    Options granted under the 2000 Equity Incentive Plan must generally be
exercised within ninety (90) days after the end of the optionee's status as an
employee, director or consultant of ours, or within 12 months after the
optionee's termination by reason of his or her disability or within 18 months
after the optionee's termination by reason of his or her death, but in no event
later than the expiration of the option's term.

    Acceptable consideration for the purchase of common stock issued under the
2000 plan will be determined by the board of directors and may include cash,
common stock previously owned by the optionee, a deferred payment arrangement
and other legal consideration approved by the board.

    SECTION 162(M) LIMIT.  Section 162(m) of the Internal Revenue Code of 1986
denies an income tax deduction to publicly held corporations for certain
compensation paid to specified employees in a taxable year to the extent that
the compensation exceeds $1 million, unless the compensation constitutes
"performance-based compensation." In order to ensure that option grants under
the 2000 Equity Incentive Plan constitute "performance-based compensation," no
person may be granted options under the 2000 Equity Incentive Plan covering more
than 2,500,000 shares of common stock in any calendar year. Under its general
authority to grant options, the board of directors has the implicit authority to
reprice outstanding options or to offer optionees the opportunity to replace
outstanding options with new options for the same or a different number of
shares. Both the original and new options will count toward the Section 162(m)
limitation.

    STOCK PURCHASE RIGHTS.  In the case of stock purchase rights, unless the
administrator determines otherwise, the restricted stock purchase agreement
shall grant us a repurchase option exercisable upon the voluntary or involuntary
termination of the purchaser's employment or consulting relationship with us for
any reason, including death or disability. The purchase price for shares
repurchased under the restricted stock purchase agreement will be the original
price paid by the purchaser and may be paid by cancellation of any indebtedness
of the purchaser to us. The repurchase option shall lapse at a rate determined
by the administrator.

    RESTRICTIONS ON TRANSFERABILITY OF STOCK AWARDS.  Except as otherwise
provided in a stock award, options and stock purchase rights granted under the
2000 Equity Incentive Plan are generally not transferable by the optionee, and
each option and stock purchase right is exercisable during the lifetime of the
optionee only by the optionee.

    CHANGES OF CONTROL.  The 2000 Equity Incentive Plan provides that in the
event of a change in control of Oplink including our merger with or into another
corporation, or a sale of substantially all of our assets, each stock award
shall be assumed or an equivalent stock award substituted for by the successor
corporation. If the outstanding stock awards are not assumed or substituted for
by the

                                       58
<PAGE>
successor corporation, then the vesting of such stock awards shall accelerate
immediately prior to the consummation of the transaction and will terminate with
the consummation of the transaction.

    AUTHORIZED SHARES.  When the 2000 Equity Incentive Plan takes effect, it
will have a total of 20,000,000 shares of our common stock reserved for issuance
under the plan. No options, stock bonuses or stock purchase rights have been
granted under the plan. On each January 1 beginning on January 1, 2001, and
ending January 1, 2010, this reserve will automatically be increased by the
greater of the total number of shares of common stock for which stock options,
stock bonuses and stock purchase rights were granted in the preceding calendar
year, or 5.0% of the total outstanding common stock on that date on a fully
diluted basis; provided, that the board may designate a smaller number of shares
by which the reserve will increase on a particular date. Shares of common stock
which are covered by a stock option granted under the plan which has expired or
terminated without having been exercised will be added to the above reserve of
the plan. Over the ten-year term of the 2000 Equity Incentive Plan, no more than
25,000,000 shares may be reserved for issuance pursuant to the exercise of
incentive stock options.

    AMENDMENT AND TERMINATION OF THE 2000 EQUITY INCENTIVE PLAN.  The board will
have the authority to amend, suspend or terminate the 2000 Equity Incentive
Plan, as long as this action does not affect any shares of common stock
previously issued and sold or any option previously granted under the 2000
Equity Incentive Plan. Unless earlier terminated, the 2000 Equity Incentive Plan
will terminate automatically one day prior to the tenth anniversary of the date
of the adoption of the plan by the board.

2000 NON-EMPLOYEE DIRECTOR STOCK OPTION GRANTS

    The 2000 Equity Incentive Plan provides for the automatic grant of
nonstatutory stock options to purchase shares of common stock to our
non-employee directors.

    AUTOMATIC GRANTS.  Upon the completion of this offering, beginning 2001, on
the day after our annual stockholders' meeting, any person who is then a
non-employee director and who is elected at such annual meeting will
automatically be granted an option to purchase 72,000 shares of common stock.
These grants will vest over a three-year period and will vest on a monthly
basis. Any non-employee director who is elected or appointed to the board during
a three-year term will automatically be granted an option to purchase a pro rata
portion of shares based on the number of months remaining in the term.

    ADMINISTRATION.  The board of directors will administer automatic option
grants to non-employee directors, unless and until it delegates administration
to a committee.

    TERMS OF OPTIONS.  Options granted to non-employee directors will generally
be subject to the following terms:

    - the exercise price of options granted will be equal to the fair market
      value of our common stock on the date of grant;

    - no option granted may be exercised after the expiration of 10 years from
      the date it was granted;

    - options granted will not be transferable other than by will or by the laws
      of descent and distribution and will be exercisable during the life of the
      optionee only by the optionee;

    - an optionee may designate a beneficiary, who may exercise the option
      following the optionee's death; and

    - an optionee whose service relationship with us or any of our affiliates,
      whether as a non-employee director of the company or subsequently as an
      employee, director or consultant of

                                       59
<PAGE>
      either the company or one of our affiliates, ceases for any reason may
      exercise vested options for the term provided in the option agreement,
      which is generally 12 months, or 18 months in the event of the optionee's
      death. However, an option may not be exercised after the expiration of its
      term.

    CHANGES OF CONTROL.  The 2000 Equity Incentive Plan will provide that in the
event of a change of control of our company, including our merger with or into
another corporation, or a sale of substantially all of our assets, each option
held by a non-employee director granted under the automatic grant provisions of
the 2000 Equity Incentive Plan shall immediately vest in full.

2000 EMPLOYEE STOCK PURCHASE PLAN

    In July 2000, our board of directors adopted the 2000 Employee Stock
Purchase Plan which authorizes the issuance of shares of our common stock
pursuant to purchase rights granted to our employees or to employees of any of
our affiliates. We expect that the 2000 purchase plan will be approved by our
stockholders prior to completing this offering. The purchase plan is intended to
qualify as an employee stock purchase plan within the meaning of Section 423 of
the Code. The purchase plan provides a means by which employees may purchase our
common stock through payroll deductions. As of the date hereof, no shares of
common stock have been purchased under the purchase plan.

    ADMINISTRATION.  The purchase plan is administered by the board of
directors. The board of directors may delegate authority to administer the
purchase plan to a committee. Subject to the terms of the plan, the board of
directors or its authorized committee, determines when and how rights to
purchase shares will be granted and the provisions of each offering of rights.
Under the plan, we may specify offerings with a duration of not more than 27
months, and may specify shorter purchase periods within each offering. The first
offering will begin on the effective date of this offering and be approximately
[6] months in duration, with purchases occurring every six months. Unless
otherwise determined by the board of directors, common stock is purchased for
accounts of employees participating in the purchase plan at a price per share
equal to the lower of:

    - 85% of the fair market value of a share of our common stock on the date of
      commencement of participation in the offering; or

    - 85% of the fair market value of a share of our common stock on the date of
      purchase.

    ELIGIBILITY.  The purchase plan is implemented by offerings of rights to
eligible employees. Generally, all regular employees, including executive
officers, who work at least 20 hours per week and are customarily employed by us
or by one of our affiliates for at least five months per calendar year may
participate in the purchase plan and may authorize payroll deductions of up to
20% of their earnings for the purchase of stock under the purchase plan.
Eligible employees may be granted rights only if the rights, together with any
other rights granted under all employee stock purchase plans, do not permit such
employee's rights to purchase our stock to accrue at a rate which exceeds
$25,000 of the fair market value of such stock for each calendar year in which
such rights are outstanding. No employee shall be eligible for the grant of any
rights under the purchase plan if immediately after such rights are granted,
such employee has voting power over 5% or more of our outstanding capital stock
measured by vote or value.

    CHANGES OF CONTROL.  The purchase plan provides that in the event of a
change of control of our company, including our merger with or into another
corporation, or a sale of substantially all of our assets as described in the
plan, the surviving entity may assume or substitute for rights outstanding

                                       60
<PAGE>
under the purchase plan. If the surviving entity does not assume or substitute
for outstanding rights, then the board of directors has discretion to cause:

    - the rights to continue in full force and effect; or

    - a participant's accumulated payroll deductions to be used to purchase
      shares, immediately prior to the change in control, and their outstanding
      rights thereafter to be terminated.

    AUTHORIZED SHARES.  The purchase plan initially authorizes the issuance of
four million shares of common stock under the purchase plan which amount will be
increased each January 1, beginning January 1, 2001, and ending January 1, 2010,
by the greater of the total number of shares issued under the plan during the
preceding calendar year or 1.5% of the number of shares of common stock
outstanding on that date. However, the board of directors has the authority to
designate a smaller number of shares by which the authorized number of shares of
common stock will be increased on that date. A maximum of 20,000,000 shares may
be issued during the term of the purchase plan.

    AMENDMENT AND TERMINATION OF THE PLAN.  The board has the authority to
amend, suspend or terminate the purchase plan. Unless earlier terminated, the
purchase plan will terminate automatically one day prior to the tenth
anniversary of the date of the adoption of the plan by the Board.

401(k) PLAN

    In January 1997, we adopted the Oplink Communications, Inc. 401(k) Profit
Sharing Plan, which covers all of our eligible employees who have completed one
month of service and are at least 21 years old. The 401(k) Plan excludes from
participation all collectively bargained and non-resident alien employees. The
401(k) Plan is intended to qualify under Section 401(a) of the Internal Revenue
Code of 1986 and the 401(k) Plan trust is intended to qualify under Section
501(a) of the Internal Revenue Code. All contributions to the 401(k) Plan by
eligible employees or by us, and the investment earnings thereon are not taxable
to such employees until withdrawn, and any contributions we may make are
expected to be deductible by us when made. Our eligible employees may elect to
reduce their eligible compensation by up to 15%, subject to statutorily
prescribed limits, and to have such compensation reductions contributed on their
behalf to the 401(k) Plan. The 401(k) Plan permits, but does not require, us to
make matching contributions to the 401(k) Plan. To date, we have not made any
matching contributions.

                           RELATED PARTY TRANSACTIONS

    Other than compensation agreements and other arrangements, which are
described as required in "Management," and the transactions described below,
since July 1, 1997, there has not been, nor is there currently proposed, any
transaction or series of similar transactions to which we were or will be a
party:

    - in which the amount involved exceeded or will exceed $60,000; and

    - in which any director, executive officer, holder of more than 5% of our
      common stock on an as-converted basis or any member of their immediate
      family had or will have a direct or indirect material interest.

INVESTOR RIGHTS AGREEMENT


    We have entered into an agreement with Cisco Systems the holders of our
preferred stock, including entities with which our directors are affiliated,
that provides these stockholders certain rights relating to the registration of
their shares of common stock issuable upon conversion of the preferred stock.
The preferred stock will convert to common stock on a one-to-one ratio
immediately prior to this offering. The weighted average price of the preferred
stock is $0.53. These registration rights do not apply to this offering, but
will survive this offering and will terminate no later than eight years after
the closing date of this offering. This agreement also entitles the holders of
our preferred stock to rights to receive financial information regarding us and
a right of first refusal to purchase shares of our stock we issue, both of which
rights terminate upon the closing of this offering.


INDEMNIFICATION AGREEMENTS


    We expect to enter into indemnification agreements with each of our
directors and executive officers prior to completing this offering. These
indemnification agreements and our certificate of incorporation and bylaws
require us to indemnify our directors and executive officers to the fullest
extent permitted by Delaware law. Please see "Management--Limitations on
Directors' Liability and Indemnification."



EMPLOYMENT AGREEMENTS, OFFICER LOANS AND CHANGE OF CONTROL ARRANGEMENTS


    We have entered into an employment agreement with Frederick R. Fromm, our
President. Under the terms of the agreement, Mr. Fromm is entitled to an annual
salary of $250,000, a $1 million supplemental life insurance policy in favor of
Mr. Fromm's designee and a relocation bonus of $50,000.

    Mr. Fromm also received an option to purchase 1,600,000 shares of our common
stock. The option is subject to the following vesting schedule: 25% of the
shares shall vest one year after the start of employment at Oplink with the
balance vesting equally on a monthly basis thereafter. In the event of a change
of control within the first year of employment, the higher of 25% of the shares,
or shares having a value of $10 million, shall immediately vest. In the event of
termination without cause within the first year of employment, the higher of
12.5% of the shares, or shares having a value of $5 million, shall immediately
vest. Mr. Fromm also has the right to purchase up to 50,000 shares of our common
stock at the then current fair market value under the 2000 Equity Incentive Plan
for each year of employment.

    In July 2000, we loaned Mr. Fromm an aggregate of $400,000. The loan accrues
interest at the rate of 6.5% per annum. The outstanding principal and any
accrued and unpaid interest is due and payable in two equal installments on July
2002 and July 2004.

    We have entered into change of control arrangements with four of our
directors, Ian Jenks, Terence P. Brown, Leonard J. LeBlanc, David Spreng, and
Edward Labuda, the Chairman of our

                                       62
<PAGE>
Scientific Advisory Board, that provide for full acceleration of all unvested
options in the event of a change of control. The form of option grant notice for
automatic grants to non-employee directors under our 2000 Equity Incentive Plan
also provides for full acceleration of all unvested options in the event of a
change of control for all such grants following the closing of this offering.

    We have entered into an agreement with Bruce Horn, our Chief Financial
Officer, that provides for acceleration of 25% of the unvested options in the
event of a change of control prior to April 24, 2001.


    We have entered into an agreement with Jeff Friedman, our Associate General
Counsel, that provides for acceleration of 25% of the unvested options if
Mr. Friedman is terminated without cause following a change of control which
occurs prior to August 15, 2001.



    We have also entered into an agreement with Daryl Eigen, our Vice President
of Sales and Marketing, that provides for acceleration of 25% of the unvested
options if Mr. Eigen is terminated without cause following a change of control
which occurs prior to August 28, 2001.

their affiliates. These transactions will continue to be on terms no less
favorable to us than we could obtain from unaffiliated third parties.

                          DESCRIPTION OF CAPITAL STOCK

    Upon completion of this offering, our authorized capital stock will consist
of 400 million shares of common stock, $0.001 par value, and 20 million shares
of undesignated preferred stock, $0.001 par value. The following description of
our capital stock does not purport to be complete and is subject to, and
qualified in its entirety by, our certificate of incorporation and bylaws, which
we have included as exhibits to the registration statement of which this
prospectus forms a part.

COMMON STOCK


    As of July 31, 2000, there were 136,764,422 shares of common stock
outstanding, held of record by 154 stockholders. This amount assumes the
conversion of all outstanding shares of preferred stock into common stock, which
is to occur upon the closing of this offering. In addition, as of July 31, 2000,
there were 22,363,744 shares of common stock subject to outstanding options and
warrants to purchase 268,904 shares of common stock and 80,000 shares of
series C preferred stock. Upon completion of this offering, there will be
155,850,694 shares of common stock outstanding, assuming conversion into common
stock of the promissory note issued to Cisco Systems based on a public offering
price of $11.00 per share, and assuming no exercise of outstanding stock options
or warrants or the underwriters' over-allotment option.


    The holders of common stock are entitled to one vote per share on all
matters to be voted upon by the stockholders. Subject to preferences that may be
applicable to any outstanding preferred stock, the holders of common stock are
entitled to receive ratably dividends, if any, as may be declared from time to
time by the board of directors out of funds legally available for that purpose.
See "Dividend Policy." In the event of our liquidation, dissolution or winding
up, the holders of common stock are entitled to share ratably in all assets
remaining after payment of liabilities, subject to prior distribution rights of
preferred stock, if any, then outstanding. The common stock has no preemptive or
conversion rights or other subscription rights. There are no redemption or
sinking fund provisions applicable to the common stock. All outstanding shares
of common stock are fully paid and nonassessable, and the shares of common stock
to be issued upon the closing of this offering will be fully paid and
nonassessable.

PREFERRED STOCK

    All of our outstanding shares of convertible preferred stock will convert
into shares of common stock on a one-to-one basis immediately prior to
completion of this offering. Following the completion of this offering, our
board of directors will have the authority, without any further action by our
stockholders, to designate and issue up to 20 million shares of preferred stock
in one or more series and to designate the rights, preferences and privileges of
each series, any or all of which may be greater than the rights of the common
stock. The effect of the issuance of any shares of preferred stock upon the
rights of holders of the common stock might include, among other things,
restricting dividends on the common stock, diluting the voting power of the
common stock, impairing the liquidation rights of the common stock and delaying
or preventing a change in control of Oplink without further action by the
stockholders. We have no present plans to issue any shares of preferred stock.

WARRANTS

    At July 31, 2000, there were outstanding warrants to purchase a total of
268,904 shares of common stock and 80,000 shares of series C preferred stock.
The warrants to purchase common stock and series C preferred stock will expire
in January 2002 and March 2003, respectively, unless earlier exercised. Upon
completion of this offering, the series C preferred stock warrant will become
exercisable for shares of common stock.

REGISTRATION RIGHTS

    The holders of 110,103,344 shares of common stock, as converted, and the
holder of a warrant to purchase 80,000 shares of common stock, as converted, or
their permitted transferees are entitled to

                                       67
<PAGE>
certain rights with respect to registration of the shares under the Securities
Act at any time after 180 days following the closing of this offering. Under the
terms of the agreements between us and the holders of the registrable
securities, upon the written request from holders of of at least 30% of the
registrable securities then outstanding, the holders may require on two
occasions that we, at our expense, file a registration statement under the
Securities Act, with respect to the registrable securities, provided that at
least 30% of the registrable securities then outstanding would be included in
the proposed registration or the anticipated public offering price of the
proposed registration would be at least $10 million. In addition, any holder of
the registrable securities then outstanding, may at our expense require that we
register their shares for public resale on Form S-3 or similar short-form
registration, provided that we are eligible to use Form S-3 or similar
short-form registration, and provided further that the value of the securities
to be registered is at least $500,000. Furthermore, in the event we elect to
register any of our shares of common stock after this offering for purposes of
effecting any public offering, the holders of registrable securities are
entitled, at our expense, to include their shares of common stock in the
registration, subject to the right of the underwriter to reduce the number of
shares proposed to be registered in view of market conditions.

ANTI-TAKEOVER PROVISIONS

    Certain provisions of Delaware law and our certificate of incorporation and
bylaws could make it more difficult to acquire us by means of a tender offer, a
proxy contest or otherwise and the removal of incumbent directors. These
provisions, summarized below, are expected to discourage certain types of
coercive takeover practices and inadequate takeover bids and to encourage
persons seeking to acquire control of us to first negotiate with us. We believe
that the benefits of increased protection of our potential ability to negotiate
with the proponent of an unfriendly or unsolicited proposal to acquire or
restructure us outweigh the disadvantages of discouraging takeover or
acquisition proposals because, among other things, negotiation of these
proposals could result in an improvement of their terms.

    DELAWARE LAW.  We are subject to Section 203 of the Delaware General
Corporation Law, an anti-takeover law. In general, Section 203 prohibits a
publicly held Delaware corporation from engaging in a "business combination"
with an "interested stockholder" for a period of three years following the date
the person became an interested stockholder, unless, with exceptions, the
business combination or the transaction in which the person became an interested
stockholder is approved in a prescribed manner. Generally, a business
combination includes a merger, asset or stock sale, or other transaction
resulting in a financial benefit to the interested stockholder, and an
interested stockholder is a person who, together with affiliates and associates,
owns, or within three years prior to the determination of interested stockholder
status, did own, 15% or more of a corporation's voting stock. The existence of
this provision would be expected to have an anti-takeover effect with respect to
transactions not approved in advance by the board of directors, including
discouraging attempts that might result in a premium over the market price for
the shares of common stock held by stockholders.

    CERTIFICATE OF INCORPORATION AND BYLAWS PROVISIONS.  Our certificate of
incorporation and bylaws require that any action required or permitted to be
taken by our stockholders must be effected at a duly called annual or special
meeting of the stockholders and may not be effected by a consent in writing. In
addition, special meetings of our stockholders may be called only by the board
of directors or certain of our officers. Our certificate of incorporation and
bylaws also provide that, beginning upon the closing of this offering, our board
of directors will be divided into three classes, with each class serving
staggered three-year terms, and that certain amendments of the certificate of
incorporation and of the bylaws require the approval of holders of at least
66.7% of the voting power of all outstanding stock. These provisions may have
the effect of deterring hostile takeovers or delaying changes in control or
management of Oplink.

TRANSFER AGENT AND REGISTRAR

    The transfer agent and registrar for the common stock is Bank of New York.

                                       68

                        SHARES ELIGIBLE FOR FUTURE SALE

    Prior to this offering, there has been no market for our common stock.
Future sales of substantial amounts of common stock in the public market could
reduce market prices prevailing from time to time. Furthermore, since only a
limited number of shares will be available for sale shortly after this offering
because of contractual and legal restrictions on resale described below, sales
of substantial amounts of common stock in the public market after the
restrictions lapse could reduce the market price of our stock and our ability to
raise equity capital in the future.


    Upon completion of the offering, we will have 155,850,694 shares of common
stock outstanding, assuming conversion into common stock of the promissory note
issued to Cisco Systems based on a public offering price of $11.00 per share,
and assuming no exercise of the underwriters' over-allotment option and no
exercise of outstanding options and warrants and based upon the number of shares
outstanding as of July 31, 2000. Of these shares, the 13,700,000 shares sold in
this offering will be freely tradable without restriction or further
registration under the Securities Act, unless such shares are purchased by our
"affiliates," as that term is defined in Rule 144 under the Securities Act. The
remaining shares held by existing stockholders, and any shares purchased by
affiliates in this offering, will be "restricted securities" as that term is
defined in Rule 144 under the Securities Act. Our executive officers, directors
and stockholders holding at least five percent of our outstanding securities
will hold 77,916,806 shares of the restricted shares. Restricted shares may be
sold in the public market only if registered or if they qualify for an exemption
from registration under Rules 144, 144(k) or 701 under the Securities Act, which
are summarized below.


    Subject to the operation of lock-up agreements described below, upon
completion of this offering, the holders of 110,103,344 shares of common stock,
or their transferees, will be entitled to certain rights to require the
registration of such shares under the Securities Act. Registration of such
shares under the Securities Act would result in such shares becoming freely
tradable without restriction under the Securities Act, except for shares
purchased by our affiliates, immediately upon the effectiveness of such
registration. See "Description of Capital Stock--Registration Rights."

LOCK-UP AGREEMENTS

    We, our officers, directors and stockholders holding approximately
119,616,756 shares of common stock have agreed that, for a period of 180 days
from the date of the final prospectus, we and they will not, subject to some
exceptions, transfer or otherwise dispose of any shares of common stock or any
securities convertible into or exercisable or exchangeable for common stock. As
a result of these contractual restrictions, notwithstanding possible earlier
eligibility for sale under the provisions of Rules 144 and 701 of the Securities
Act discussed below, shares subject to these lock-up agreements may not be sold
until the shares are released from the agreements or the agreements expire or
unless prior written consent is received from FleetBoston Robertson
Stephens Inc. Any early waiver of the lock-up agreements by the underwriters,
which, if granted, could permit sales of a substantial number of shares and
could adversely affect the trading price of our shares, may not be accompanied
by an advance public announcement by us.

RULE 144

    In general, under Rule 144, beginning 90 days after the date of the final
prospectus, a person or persons whose shares are aggregated, who has
beneficially owned restricted shares for at least one year, including a person
who may be deemed our Rule 144 affiliate, would be entitled to sell within any
three-month period a number of shares that does not exceed the greater of:

    - one percent of the number of shares of our common stock then outstanding;
      or

                                       69
<PAGE>
    - the average weekly trading volume of our common stock during the four
      calendar weeks preceding the filing of a notice on Form 144 with respect
      to the proposed sale.

    Sales under Rule 144 are also subject to manner of sale provisions and
notice requirements and to the availability of current public information about
us. We are unable to estimate accurately the number of restricted shares that
will be sold under Rule 144 because this will depend in part on the market price
of our common stock, the personal circumstances of the seller and other factors.

    Under Rule 144(k), a person who is not deemed to have been our Rule 144
affiliate at any time during the 90 days preceding a sale, and who has
beneficially owned for at least two years the shares proposed to be sold, would
be entitled to sell those shares under Rule 144(k) without complying with the
manner of sale, public information, volume limitation or notice provisions of
Rule 144. Therefore, subject to the lock-up agreements, these shares may be sold
upon completion of this offering.

RULE 701

    Beginning 90 days after the date of this prospectus as of July 31, 2000,
23,446,822 shares of common stock issuable upon exercise of the options granted
by us prior to the effective date of the registration statement will be eligible
for sale in the public market pursuant to Rule 701 under the Securities Act,
subject to the lock-up agreements. In general, Rule 701 permits resales of
shares issued under specified compensatory benefit plans and contracts
commencing 90 days after the issuer becomes subject to the reporting
requirements of the Securities Exchange Act in reliance upon Rule 144, but
without compliance with restrictions, including the holding period requirements,
contained in Rule 144.

REGISTRATION STATEMENTS ON FORM S-8

    Following this offering, we intend to file under the Securities Act one or
more registration statements on Form S-8 to register all of the shares of our
common stock eligible for this form of registration statement:

    - issuable upon exercise of outstanding options granted pursuant to our
      stock option and equity incentive plans;

    - reserved for future option grants pursuant to individual option agreements
      or these plans; and

    - that we intend to offer for sale to our employees pursuant to our employee
      stock purchase plan.

These registration statements are expected to become effective upon filing.
Shares covered by these registration statements will be subject to vesting
provisions and subject to expiration of the lock-up agreements. In the case of
Rule 144 affiliates only, these shares will also remain subject to the
restrictions of Rule 144 other than the holding period requirement.

     UNITED STATES FEDERAL TAX CONSIDERATIONS FOR NON-UNITED STATES HOLDERS

    The following is a summary of certain United States federal income and
estate tax consequences of the ownership and disposition of our common stock by
non-U.S. holders. As used herein, "non-U.S. holder" means any person or entity
that holds our common stock, other than:

    - an individual citizen or resident of the U.S.;

    - a corporation or partnership created or organized in or under the laws of
      the U.S., or of any state of the U.S. or the District of Columbia, other
      than any partnership treated as foreign under U.S. Treasury Regulations;

    - an estate the income of which is includable in gross income for U.S.
      federal income tax purposes regardless of its source; or

    - in general, a trust if a court within the U.S. may exercise primary
      supervision over the administration of the trust and if one or more U.S.
      persons have the authority to control all substantial decisions of the
      trust.

    This summary is based on provisions of the U.S. Internal Revenue Code of
1986, as amended, existing, temporary and proposed U.S. Treasury Regulations
promulgated thereunder and administrative and judicial interpretations of each,
all as of the date hereof and all of which are subject to change, possibly on a
retroactive basis. This summary is for general information only. It does not
address aspects of U.S. federal taxation other than income and estate taxation,
and does not address all aspects of U.S. federal income and estate taxation.
This summary does not discuss all the tax consequences that may be relevant to a
non-U.S. holder in light of the holder's particular circumstances, for instance,
insurance companies, tax-exempt organizations, broker-dealers, and financial
institutions. In addition, this summary does not address any state, local, or
foreign tax considerations that may be relevant to a non-U.S. holder's decision
to purchase shares of our common stock.

    PROSPECTIVE PURCHASERS ARE URGED TO CONSULT THEIR TAX ADVISORS REGARDING THE
PARTICULAR U.S. FEDERAL INCOME AND ESTATE TAX CONSEQUENCES, AS WELL AS OTHER
U.S. FEDERAL, STATE, AND LOCAL TAX CONSEQUENCES, AND THE NON-U.S. TAX
CONSEQUENCES, TO THEM OF OWNING AND DISPOSING OF SHARES OF OUR COMMON STOCK.

INCOME TAX

DIVIDENDS

    Subject to the discussion below, dividends paid to a non-U.S. holder
generally will be subject to withholding of U.S. income tax at the rate of 30%
of the amount of the dividend, or such lower rate as may be prescribed by an
applicable income tax treaty.

    However, if dividends we pay are effectively connected with a non-U.S.
holder's conduct of a trade or business in the U.S. and, if a tax treaty
applies, are attributable to a U.S. permanent establishment, or, if the holder
is an individual, a "fixed base" of the non-U.S. holder, the 30% withholding tax
generally will not apply, and the non-U.S. holder generally will be subject to
tax on such dividends on a net basis in the same manner as holders that are U.S.
persons, provided the non-U.S. holder files appropriate IRS forms with us. An
additional branch profits tax of 30%, or such lower rate as may be prescribed by
an applicable income tax treaty, may apply if the non-U.S. holder is a
corporation.

    Under current U.S. Treasury Regulations, in determining whether a holder is
eligible for the benefits of an income tax treaty, dividends paid to an address
in a foreign country are presumed to be paid to a resident of that country,
absent knowledge to the contrary. However, under new U.S. Treasury Regulations
generally effective for dividend payments made after December 31, 2000, a

                                       71
<PAGE>
non-U.S. holder desiring to claim the benefits of an applicable tax treaty must
satisfy certification and other requirements and must provide us with a taxpayer
identification number unless an exception applies. In addition, under these new
Treasury Regulations, in the case of common stock held by a foreign partnership,
this certification requirement may be applied to the partners, and not the
partnership, and the partnership must provide certain information, including a
U.S. taxpayer identification number. These new regulations also provide
look-through rules for tiered partnerships. A non-U.S. holder that is eligible
for a reduced rate of U.S. withholding tax pursuant to a tax treaty may obtain a
refund of any excess amounts withheld by filing an appropriate claim for refund
with the IRS.

DISPOSITION OF OUR COMMON STOCK

    Generally, non-U.S. holders will not be subject to U.S. federal income tax,
or withholding thereof, in respect of gain recognized on a disposition of our
common stock unless:

    - the gain is effectively connected with the holder's conduct of a trade or
      business within the U.S., or, if a tax treaty applies, is attributable to
      a permanent establishment or fixed base of the holder in the U.S.; in any
      such case such gain will be subject to regular graduated U.S. income tax
      rates and the branch profits tax described above may also apply if the
      non-U.S. holder is a corporation;

    - in the case of a non-U.S. holder who is a non-resident alien individual
      and holds our common stock as a capital asset, the holder is present in
      the U.S. for 183 or more days in the taxable year of the sale and other
      conditions are met;

    - we are or have been a "United States real property holding corporation"
      for U.S. federal income tax purposes and certain other conditions are met;
      we do not believe we are or have been a United States real property
      holding corporation and do not expect to become one in the future; or

    - the holder is subject to tax pursuant to U.S. federal income tax
      provisions applicable to certain U.S. expatriates.

ESTATE TAX

    If an individual non-U.S. holder owns, or is treated as owning, our common
stock at the time of his or her death, such stock would be includable in the
individual's gross estate for U.S. federal estate tax purposes and may be
subject to U.S. federal estate tax imposed on the estates of nonresident aliens,
in the absence of a contrary provision contained in an applicable tax treaty.

BACKUP WITHHOLDING AND INFORMATION REPORTING

DIVIDENDS

    Generally, we must report annually to the IRS and to each non-U.S. holder
the amount of dividends that we paid to a holder, and the amount of tax that we
withheld on those dividends. This information may also be made available to the
tax authorities of a country in which the non-U.S. holder resides or is
established.

    Under current law, dividends paid on our common stock to a non-U.S. holder
at an address outside the U.S. are generally exempt from backup withholding tax,
imposed at a 31% rate, and U.S. information reporting requirements, but not from
regular withholding tax as discussed above. Backup withholding tax and
information reporting generally will apply to dividends paid to a non-U.S.
holder at an address in the U.S. if the holder fails to establish an exemption
or to furnish other information. Under the Treasury Regulations that are
applicable to dividends paid after December 31, 2000, a

                                       72
<PAGE>
non-U.S. person must generally provide proper documentation establishing the
person's non-U.S. status to a withholding agent in order to avoid backup
withholding tax.

BROKER SALES

    Payments of proceeds from the sale of our common stock by a non-U.S. holder
made to or through a U.S. office of a broker are generally subject to both
information reporting and backup withholding tax unless the holder certifies its
non-U.S. status under penalties of perjury or otherwise establishes entitlement
to an exemption. Payments of proceeds from the sale of our common stock by a
non-U.S. holder made to or through a non-U.S. office of a broker generally will
not be subject to information reporting or backup withholding. However, payments
made to or through certain non-U.S. offices, including the non-U.S. offices of a
U.S. broker and foreign brokers with certain types of relationships to the U.S.,
are generally subject to information reporting, but not backup withholding,
unless the holder certifies its non-U.S. status under penalties of perjury or
otherwise establishes entitlement to an exemption.

    Backup withholding is not an additional tax. A non-U.S. holder may obtain a
refund of any excess amounts withheld under the backup withholding rules by
filing an appropriate claim for refund with the IRS.

    Non-U.S. holders should consult their tax advisors regarding the application
of information reporting and backup withholding in their particular situation,
including the availability of an exemption from such requirements and the
procedures for obtaining such an exemption, as well as the effect of the new
Treasury Regulations generally effective for payments made after December 31,
2000.

</TABLE>

    The representatives have advised us that the underwriters propose to offer
the shares of common stock to the public at the public offering price set forth
on the cover page of this prospectus and to certain dealers at that price less a
concession of not in excess of $      per share, of which $      may be
reallowed to other dealers. After this offering, the public offering price,
concession and reallowance to dealers may be reduced by the representatives. No
such reduction shall change the amount of proceeds to be received by us as set
forth on the cover page of this prospectus. The common stock is offered by the
underwriters as stated herein, subject to receipt and acceptance by them and
subject to their right to reject any offer in whole or in part.

    Prior to this offering, there has been no public market for the common
stock. Consequently, the public offering price for the common stock offered by
this prospectus has been determined through negotiations among the
representatives and us. Among the factors considered in such negotiations were
prevailing market conditions, certain of our financial information, market
valuations of other companies that we and the representatives believe to be
comparable to us, estimates of our business potential, the present state of our
development and other factors deemed relevant.

    The underwriters have advised us that they do not expect sales to
discretionary accounts to exceed five percent of the total number of shares
offered.

OVER-ALLOTMENT OPTION

    We have granted to the underwriters an option, exercisable during the 30-day
period after the date of this prospectus, to purchase up to
2,055,000 additional shares of common stock to cover over-allotments, if any, at
the public offering price less the underwriting discount set forth on the cover
page of this prospectus. If the underwriters exercise their over-allotment
option to purchase any of the 2,055,000 additional shares of common stock, the
underwriters have severally agreed, subject to certain conditions, to purchase
approximately the same percentage thereof as the number of shares to be
purchased by each of them bears to the total number of shares of common stock
offered in this offering. If purchased, these additional shares will be sold by
the underwriters on the same terms as those on which the shares offered hereby
are being sold. We will be obligated, pursuant to the over-allotment option, to
sell shares to the underwriters to the extent the over-allotment option is
exercised. The underwriters may exercise the over-allotment option only to cover
over-allotments made in connection with the sale of the shares of common stock
offered in this offering.

INDEMNITY

    The underwriting agreement contains covenants of indemnity among the
underwriters and us against certain civil liabilities, including liabilities
under the Securities Act of 1933, and liabilities arising from breaches of
representations and warranties contained in the underwriting agreement.

LOCK-UP AGREEMENTS


    Each of our executive officers and directors and stockholders collectively
holding approximately 94.8% of our common stock have agreed, subject to
specified exceptions, not to offer to sell, contract to sell, or otherwise sell,
dispose of, loan, pledge or grant any rights with respect to any shares of
common stock or any options or warrants to purchase any shares of common stock,
or any securities convertible into or exchangeable for shares of common stock
owned as of the date of this prospectus or thereafter acquired directly by those
holders or with respect to which they have the power of disposition, without the
prior written consent of FleetBoston Robertson Stephens Inc. This restriction
terminates after the close of trading of the shares on the 180th day of (and
including) the day the shares commenced trading on the Nasdaq National Market.
However, FleetBoston Robertson Stephens Inc. may, in its sole discretion and at
any time or from time to time before the termination of the 180-day period,
without notice, release all or any portion of the securities subject to lock-up
agreements. There are no existing agreements between the representatives and any
of our shareholders or optionholders who have executed a lock-up agreement
providing consent to the sale of shares prior to the expiration of the lock-up
period.


    In addition, we have agreed that during the lock-up period we will not,
without the prior written consent of FleetBoston Robertson Stephens Inc.,
subject to certain exceptions, consent to the disposition of any shares held by
shareholders subject to lock-up agreements prior to the expiration of the
lock-up period, or issue, sell, contract to sell, or otherwise dispose of, any
shares of common stock, any options or warrants to purchase any shares of common
stock or any securities convertible into, exercisable for or exchangeable for
shares of common stock other than our sale of shares in this offering, the
issuance of our common stock upon the exercise of outstanding options or
warrants, and the issuance of options under existing stock option and incentive
plans provided that those options do not vest prior to the expiration of the
lock-up period. See "Shares Eligible for Future Sale."

LISTING

    We have applied for the approval to list our common stock on the Nasdaq
National Market under the symbol "OPLK."

SYNDICATE SHORT SALES

    The representatives have advised us that, on behalf of the underwriters,
they may make short sales of our common stock in connection with this offering,
resulting in the sale by the underwriters of a greater number of shares than
they are required to purchase pursuant to the underwriting agreement. The short
position resulting from those short sales will be deemed a "covered" short
position to the extent that it does not exceed the 2,055,000 shares subject to
the underwriters' over-allotment option and will be deemed a "naked" short
position to the extent that it exceeds that number. A naked short position is
more likely to be created if the underwriters are concerned that there may be
downward pressure on the trading price of the common stock in the open market
that could adversely affect investors who purchased shares in the offering. The
underwriters may reduce or close out their covered short position either by
exercising the over-allotment option or by purchasing shares in the open market.
In determining which of these alternatives to pursue, the underwriters will
consider the price at which shares are available for purchase in the open market
as compared to the price at which they may purchase shares through the
over-allotment option. Any "naked" short position will be closed out by
purchasing shares in the open market. Similar to the other stabilizing
transactions described below, open market purchases made by the underwriters to
cover all or a portion of their short position may have the effect of preventing
or retarding a decline in the market price of our common stock following this
offering. As a result, our common stock may trade at a price that is higher than
the price that otherwise might prevail in the open market.

STABILIZATION

    The representatives have advised us that, pursuant to Regulation M under the
Securities Exchange Act of 1934, they may engage in transactions, including
stabilizing bids or the imposition of penalty bids, that may have the effect of
stabilizing or maintaining the market price of the shares of common stock at a
level above that which might otherwise prevail in the open market. A
"stabilizing bid" is a bid for or the purchase of shares of common stock on
behalf of the underwriters for the purpose of fixing or maintaining the price of
the common stock. A "penalty bid" is an arrangement permitting the
representatives to claim the selling concession otherwise accruing to an
underwriter or syndicate member in connection with the offering if the common
stock originally sold by that underwriter or syndicate member is purchased by
the representatives in the open market pursuant to a stabilizing bid or to cover
all or part of a syndicate short position. The representatives have advised us
that stabilizing bids and open market purchases may be effected on the Nasdaq
National Market or otherwise and, if commenced, may be discontinued at any time.

DIRECTED SHARE PROGRAM

    At our request, certain of the underwriters have reserved up to
five percent of the shares of common stock for sale in this offering at the
initial public offering price to our directors, officers and employees and
persons who are otherwise associated with us. The number of shares of common
stock available for sale to the general public will be reduced to the extent
these individuals purchase reserved shares. Any reserved shares which are not
purchased will be offered by the underwriters on the same basis as the other
shares of common stock offered in this offering. We have agreed to indemnify
these underwriters against various liabilities and expenses, including
liabilities under the Securities Act of 1933, in connection with the sales of
directed shares.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of
  Oplink Communications, Inc.


    The reincorporation and the two-for-one stock split described in Note 1 to
the consolidated financial statements have not been consummated as of
August 29, 2000. When these have been consummated, we will be in a position to
issue the following report:


        "In our opinion, the accompanying consolidated balance sheet and the
    related consolidated statements of operations, of mandatorily redeemable
    convertible preferred stock and stockholders' deficit and of cash flows
    present fairly, in all material respects, the financial position of Oplink
    Communications, Inc. and its subsidiaries at June 30, 1999 and 2000, and the
    results of their operations and their cash flows for each of the three years
    in the period ended June 30, 2000, in conformity with accounting principles
    generally accepted in the United States. These financial statements are the
    responsibility of the Company's management; our responsibility is to express
    an opinion on these financial statements based on our audits. We conducted
    our audits of these statements in accordance with auditing standards
    generally accepted in the United States, which require that we plan and
    perform the audit to obtain reasonable assurance about whether the financial
    statements are free of material misstatement. An audit includes examining,
    on a test basis, evidence supporting the amounts and disclosures in the
    financial statements, assessing the accounting principles used and
    significant estimates made by management, and evaluating the overall
    financial statement presentation. We believe that our audits provide a
    reasonable basis for the opinion expressed above."

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1--THE COMPANY:

THE COMPANY

    Oplink Communications, Inc. (the "Company") designs, manufactures and
supplies fiber optic components and integrated optical modules that increase the
performance of optical networks. The Company provides a broad line of products
to communication equipment suppliers to enable bandwidth creation and management
within an optical network. The Company was incorporated in September 1995 and
began shipping its product for sale in 1996. In April 1999, the Company
established manufacturing operations in Zhuhai, China. In April 2000, the
Company acquired Telelight Communications, Inc., a designer and manufacturer of
passive fiber optic components in Sunnyvale, California and Fuzhou China. The
Company conducts its business within one business segment and has no
organizational structure dictated by product, service lines, geography or
customer type.

REINCORPORATION

    On July 12, 2000 the Company's Board of Directors authorized the
reincorporation of the Company in the State of Delaware. As a result of the
reincorporation, the Company is authorized to issue 400,000,000 shares of $0.001
par value Common Stock and 20,000,000 shares of $0.001 par value Convertible
Preferred Stock. The Board of Directors has the authority to issue the
undesignated Convertible Preferred Stock in one or more series and to fix the
rights, preferences, privileges and restrictions thereof. The par value and
shares of Common Stock and Convertible Preferred Stock authorized, issued and
outstanding at each balance sheet date presented, and for each period presented
in the consolidated statement of stockholders' deficit have been retroactively
adjusted to reflect the reincorporation.

STOCK SPLIT

    On August 18, 2000, the Board of Directors approved, subject to stockholder
approval, a two-for-one stock split. The consolidated financial statements and
all references to Common Stock and Preferred Stock contained in these
consolidated financial statements and notes thereto give retroactive effect to
the stock split. Stockholder approval is expected to occur prior to the
effectiveness of the Company's initial public offering.

NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

BASIS OF PRESENTATION

    The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries Zhuhai Oplink Communications, Inc. ("Zhuhai"),
Fuzhou Oplink Communications, Inc. ("Fuzhou") and Telelight Communication Inc.
("Telelight"). Zhuhai, Fuzhou and Telelight were formed in April 1999,
March 2000, and April 2000, respectively. All significant intercompany accounts
and transactions have been eliminated in consolidation.

USE OF ESTIMATES

    The preparation of financial statements in conformity with accounting
principles generally accepted in the United States requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the

NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

CASH AND CASH EQUIVALENTS

    The Company considers all highly liquid investments with a maturity of three
months or less when purchased to be cash equivalents. The Company's cash
equivalents consist of money market funds and short-term deposits.

REVENUE RECOGNITION

    The Company derives its revenue from the sale of fiber optic components and
integrated optical modules. Revenue from product sales is recognized at the
later of shipment of the product or customer acceptance, if applicable, and only
if collectibility is probable. Sales to distributors do not include the right to
return, exchange products or price protection. Revenue from sales to one
customer for which the terms of the sale includes an acceptance period is not
recognized until after receipt of written customer acceptance. Provisions for
return allowances and warranties are recorded based on historical experience at
the time revenue is recognized based on the Company's historical experience.

FOREIGN CURRENCY TRANSLATIONS

    The functional currency of the Company's foreign subsidiaries is the local
currency. In consolidation, assets and liabilities are translated at year-end
currency exchange rates and revenue and expense items are translated at average
currency exchange rates prevailing during the period. Gains and losses from
foreign currency translation are accumulated as a separate component of
stockholders' equity. At June 30, 2000, such amounts were not material. Realized
gains and losses resulting from foreign currency transactions are included in
the consolidated statement of operations.

FAIR VALUE

    The Company's financial instruments, which include cash and cash
equivalents, accounts receivable, accounts payable, accrued liabilities,
borrowings under lines of credit and capital lease obligations are reported at
cost, which approximates their fair values due to their relatively short
maturity.

CONCENTRATION OF CREDIT RISK

    Financial instruments that potentially subject the Company to a
concentration of credit risk consist of cash and cash equivalents, and accounts
receivable. Substantially all of the Company's cash and cash equivalents are
managed or held by two financial institutions. At times, such deposits may be in
excess of the amount of the insurance provided on such deposits. To date, the
Company has not experienced any losses on such deposits. The Company's accounts
receivable are derived from revenue earned from customers located in the United
States and Asia. The Company performs ongoing credit evaluations of its
customers' financial condition and generally requires no collateral from its
customers. The Company maintains an allowance for doubtful accounts based upon
the expected collection of its outstanding receivable balance.

    The following table summarizes the revenues from customers in excess of 10%
of total revenues:

</TABLE>

    At June 30, 2000, two customers accounted for 41% and 15% of total accounts
receivable, respectively.

    The Company operates in a highly competitive environment subject to rapid
technological change and emergence of new technology. Although management
believes its products and services are transferable to emerging technologies,
rapid changes in technology could have an adverse financial impact on the
Company.

    A substantial portion of the Company's manufacturing operations are located
in China and are subject to the laws and regulations of China. Operations in
China may be adversely affected by changes in the laws and regulations of China,
such as those relating to taxation, import and export tariffs, environmental
regulations, land use rights, property and other matters.

INVENTORIES

    Inventories are stated at the lower of cost or market, cost being determined
on a first-in, first-out basis. The inventory of the Company is subject to rapid
technological changes that could have an adverse affect on its realization in
future periods.

PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost. Depreciation is computed using
the straight-line method based upon the useful lives of the assets ranging from
three to five years. Leasehold improvements are amortized using the
straight-line method based upon the shorter of the estimated useful lives or the
lease term of the respective assets.

IMPAIRMENT OF LONG-LIVED ASSETS

    Periodically, the Company evaluates the recoverability of the net carrying
value of its property, plant and equipment and its intangible assets by
comparing the carrying values to the estimated future undiscounted cash flows. A
deficiency in these cash flows relative to the carrying amounts is an indication
of the need for a write-down due to impairment. The impairment write-down would
be the difference between the carrying amounts and the fair value of these
assets. A loss on impairment would be recognized by a charge to earnings.

    If an asset being tested for recoverability was acquired in a business
combination, the goodwill that arose in that business combination is included as
part of the asset in determining recoverability.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
Goodwill is allocated to the asset being tested for recoverability on a pro rata
basis using the relative fair values of the long-lived assets and identifiable
intangible assets acquired. In instances where goodwill is identified with
assets that are subject to an impairment loss, the carrying amount of the
identified goodwill shall be eliminated before making any reduction in the
carrying amount of impaired long-lived assets and identifiable intangible
assets.

INCOME TAXES

    The Company accounts for income taxes under the liability method, which
recognizes deferred tax assets and liabilities for the expected future tax
consequences of temporary differences between the tax bases of assets and
liabilities and their financial statement reported amounts, and for net
operating loss and tax credit carryforwards. The Company records a valuation
allowance against deferred tax assets when it is more likely than not that such
assets will not be realized.

ADVERTISING COSTS

    Advertising costs are expensed as incurred in accordance with SOP 97-3,
"Reporting of Advertising Costs." Advertising costs for the years ended
June 30, 1998, 1999 and 2000 were $38,000, $47,000, and $142,000, respectively.

STOCK-BASED COMPENSATION

    The Company accounts for stock-based compensation issued to employees using
the intrinsic value method of Accounting Principles Board opinion No. 25,
"Accounting for Stock issued to Employees," and, accordingly, presents
disclosure of pro forma information required under No. 123, "Accounting for
Stock-Based Compensation." Stock and other equity instruments issued to-non
employees are accounted for in accordance with SFAS No. 123 and Emerging Issues
Task Force Issue No. 96-18 and valued using the Black-Scholes option-pricing
model.

COMPREHENSIVE INCOME

    The Company's comprehensive loss approximated net losses for all periods
presented.

NET LOSS PER COMMON SHARE

    The Company computes net loss per share in accordance with SFAS No. 128,
"Earnings Per Share," and SEC Staff Accounting Bulletin ("SAB") No. 98. Under
the provisions of SFAS No. 128 and SAB No. 98, basic net loss per share is
computed by dividing the net loss attributable to holders of Common Stock by the
weighted average number of shares of Common Stock outstanding during the period.

RECENTLY ISSUED ACCOUNTING STANDARDS

    In June 1998, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities." SFAS
No. 133 establishes new standards of accounting and reporting for derivative
instruments and hedging activities. SFAS No. 133 requires that all derivatives
be recognized at fair value in the statement of financial position, and that the
corresponding gains or losses be reported either in the statement of operations
or as a component of comprehensive income (loss), depending on the type of
hedging relationship that exists.

    In July 1999, the FASB issued SFAS No. 137 "Accounting for Derivative
Instruments and Hedging Activities--Deferral of the Effective Date of FASB
Statement No. 133." SFAS No. 137 deferred the effective of SFAS No. 133 until
fiscal years beginning after June 15, 2000. Management does not believe that the
adoption of SFAS No. 137 will have a material impact on its operations of
financial position.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    In December 1999, the Securities and Exchange Commission ("SEC") issued
Staff Accounting Bulletin ("SAB") No. 101, "Revenue Recognition in Financial
Statements," which provides guidance on the recognition, presentation, and
disclosure of revenue in financial statements filed with the SEC. SAB 101
outlines the basic criteria that must be met to recognize revenue and provides
guidance for disclosures related to revenue recognition policies. Management
believes that the Company has complied with the guidance of SAB 101.

    In March 2000, the Financial Accounting Standards Board issued
Interpretation No. 44 ("FIN 44") "Accounting for Certain Transactions Involving
Stock Compensation, an Interpretation of Opinion No. 25" for (a) the definition
of employee for purposes of applying Opinion No. 25, (b) the criteria for
determining whether a plan qualifies as a noncompensatory plan, (c) the
accounting consequences of various modifications to the terms of a previously
fixed stock option or award, and (d) the accounting for an exchange of stock
compensation awards in a business combination. FIN 44 is effective July 1, 2000,
but certain conclusions cover specific events that occur after either
December 15, 1998, or January 12, 2000. The adoption of certain provisions of
FIN 44 prior to March 31, 2000 did not have a material impact on the financial
statements. Management does not expect that the adoption of the remaining
provisions will have a material effect on the financial position or results of
operations of the Company.

    In various areas, including revenue recognition, accounting standards and
practices continue to evolve. Additionally, the SEC is preparing to issue
interpretative guidance relating to SAB 101, and the FASB's Emerging Issues Task
Force continues to address revenue related accounting issues. The management of
the Company believes it is in compliance with all of the rules and related
guidance as they currently exist. However, any changes to generally accepted
accounting principles in these areas could impact the Company's future
accounting for its operations.

NOTE 4--TELELIGHT ACQUISITION

ACQUISITION

    In February 2000, the Company entered into a definitive agreement to acquire
Telelight Communication Inc. ("Telelight") in a merger transaction to be
accounted for as a purchase business combination. This acquisition was
consummated on April 6, 2000. The purchase price comprised 13,440,000 shares of
Common Stock valued at $26,880,000. The Company also anticipates incurring
approximately $200,000 in acquisition expenses, including primarily legal fees
and other direct transaction costs. The total purchase price aggregated
$27,080,000 and was allocated to the tangible and identifiable intangible assets
acquired and liabilities assumed on the basis of their relative fair values as
follows:

                                                              $27,080

</TABLE>

    The net tangible assets consist primarily of cash and cash equivalents,
accounts receivable, inventory property and equipment, accounts payable and
other liabilities.

    The developed technologies acquired in the Telelight acquisition were the
Optical Circulator product and filter products. These products have yet to gain
market acceptance or receive certain industry-standard qualifications. Given
these facts and the commodity nature of these products, minimal value was
attributed to them in the purchase price allocation.

    The in-process research and development consisted of an Optical Wavelength
Interleaver product that, as of the date of acquisition, had not yet reached
technological feasibility and had no alternative future use. The Optical
Interleaver is a compact high performance fiber optic product that segments
optical signals by wavelengths. This product makes channel spacing smaller,
thereby increasing the number of channels on a fiber optic network.

    The value of the Optical Wavelength Interleaver was determined by estimating
the net cash flows from the sale of the products resulting from the completion
of this project, reduced by the portion of the net cash flows from the revenue
attributable to core technology. The resulting cash flows were then discounted
back to their present value using a discount rate of 35%. The fair value
assigned to the core technology totaled $6,245,000, and is being amortized over
the expected life of its cash flows of four years. At the time of the
acquisition this project was approximately 80% complete. The fair value assigned
to the in-process research and development totaled $7,020,000, and was charged
to expense at the time of the acquisition. The Company has incurred
approximately $50,000 of expense subsequent to the acquisition, and in May 2000
the first qualified prototype was completed and technological feasibility was
achieved.

    The value of certain patents being assigned to Oplink was determined using
the relief from royalty methodology, which assumes that the value of the asset
equals the amount a third party would pay to

use the asset and capitalize on the related benefits of the assets. The fair
value assigned to patents of $1,086,000 is being amortized over its expected
life of four years.

    Goodwill is being amortized on a straight line basis of the estimated period
of benefit of four years.

NOTE 6--RELATED PARTY TRANSACTIONS:

INVESTOR RIGHTS AGREEMENT

    The Company has entered into an agreement with the holders of its preferred
stock, including entities with which its directors are affiliated, that provides
these stockholders certain rights relating to the registration of their shares
of common stock issuable upon conversion of the preferred stock. These rights
have been waived as to this offering by the holders of preferred stock, but will
survive this offering and will terminate no later than eight years after the
closing date of this offering. This agreement also entitles the holders of the
Company's preferred stock to rights to receive financial information regarding
the Company and a right of first refusal to purchase shares of its stock issued,
both of which rights terminate at the close of this offering.

INDEMNIFICATION AGREEMENTS

    The Company expects to enter into indemnification agreements with each of
its directors and officers prior to completing this offering. These
indemnification agreements and its certificate of incorporation and bylaws
require the Company to indemnify its directors and officers to the fullest
extent permitted by Delaware law.

SALES TO INVESTOR

    Beginning from July 1, 1998, the Company sold products to a customer who is
also one of the shareholders of the Company's Series D mandatorily redeemable
preferred stock. Sales to this customer totaled $47,000 and $524,000 for the

redeemable and classified outside of permanent equity. The carrying value of the
Preferred Stock equals its liquidation value.

    The rights, preferences, privileges and restrictions thereof are set forth
in the Company's Amended and Restated Articles of Incorporation, and are
summarized below:

DIVIDENDS

    The holders of Convertible Series A, Series B, Series C, Series D and
Series E Preferred Stock are entitled to receive noncumulative dividends at the
annual rate of $0.002, $0.0072, $0.02, $0.03 and $0.16 per share, respectively,
if and when declared by the Board of Directors. To date, the Board of Directors
has not declared any dividends.

LIQUIDATION PREFERENCE

    In the event of any liquidation or winding up of the Company, including a
merger, sale of substantially all assets, or reorganization of the Company, the
holders of Convertible Preferred Stock shall be entitled to receive in
preference to the holders of Common Stock, an amount equal to $0.025 per share
of Series A, $0.09 per share of Series B, $0.25 per share of Series C Preferred,
$0.375 per share of Series D Preferred Stock and $2.00 per share of Series E
Preferred Stock, plus any declared and unpaid dividends. All remaining assets,
if any, shall be distributed pro rata to the holders of the Common Stock and
Preferred Stock (on an as-if-converted basis).

    The Series A, B, C, D and E Preferred Stock shall rank on a parity as to the
receipt of the respective preferential amounts for each such series upon the
occurrence of liquidation. If, upon the occurrence of such an event, the assets
and funds thus distributed among the holders of Series A, B, C, D and E
Preferred Stock are insufficient to permit full payment to such holders, then
the entire assets and funds legally available for distribution shall be
distributed ratably among the holders of Series A, B, C, D and E Preferred Stock
in proportion to the preferential amount each is entitled to receive.

CONVERSION

    Each share of Series A, Series B, Series C, Series D and Series E Preferred
Stock is convertible into one share of Common Stock, at the option of the

    Each share of Convertible Preferred Stock shall be automatically converted
into Common Stock, at the then applicable conversion rate, upon the closing of
an underwritten public offering of shares of the Company which results in a per

at least $4.00 per share and aggregate proceeds of $50,000,000.

VOTING RIGHTS

    The Series A, B, C, D and E Preferred Stock will be entitled to vote, along

remaining members of the Company's Board of Directors.

COVENANTS

    Under the terms of the Preferred Stock agreements, the Company is required
to comply with certain covenants, including the timely submissions of certain
financial data. At June 30, 2000, the Company was in violation of the covenant
regarding the timely submission of financial data. Waivers obtained subsequent
to year end have allowed the Company to remain in compliance with such
covenants.

WARRANTS

    In January 1997, the Company obtained a line of credit of $500,000 to fund
the Company's operations. In connection with obtaining this line of credit and
in exchange for the waiver of bank fees, the Company issued to the bank a
warrant to purchase 268,904 shares of Common Stock. Under the terms of the
agreement, the warrant was immediately exercisable with a five year term at an
exercise price of $0.1488 per share. The most reliably determinable value
assigned to this warrant by the Company was the value of the waived bank fee
which amounted to $7,000 and was charged to operations during 1997. In
March 1998, this line of credit was increased to $1,000,000. In connection with
obtaining this increase, the Company issued an additional warrant to purchase
80,000 shares of Series C Convertible Preferred Stock. Under the terms of this
agreement, the warrant was immediately exercisable with a five year term at an
exercise price of $0.25 per share. The most reliably determinable value assigned
to this warrant by the Company was the value of the waived bank fee which
amounted to $3,000 and was charged to operations during 1998. The line of credit
expired in January of 1999. There were no borrowings under the line of credit as
of June 30, 1999 or 2000.

NOTE 8--STOCK OPTION PLANS

    In September 1995, the Board of Directors adopted the 1995 Stock Option Plan
(the "1995 Plan"). In January 1998, the Board of Directors adopted the 1998
Stock Option Plan (the "1998 Plan"). The 1995 Plan and 1998 Plan provide for the
issuance of incentive and nonqualified stock options to employees, directors and
consultants of the Company. Under the 1995 Plan and 1998 Plan, options to
purchase 6,000,000 and 33,800,000 shares of Common Stock, respectively, have
been authorized for grant. Options granted under both plans must be granted with
exercise prices not less than 100% and 85%, for incentive and nonqualified stock
options respectively, of the estimated fair value of the Company's Common Stock
on the date of grant, as determined by the Board of Directors. Options granted
to shareholders who own greater than 10% of the Company's outstanding stock must
be issued with exercise prices not less than 110% of the estimated fair value of
the Company's Common Stock on the date of grant, as determined by the Board of
Directors. Options under the both the 1995 Plan and 1998 Plan generally become
exercisable at a rate of 25% during the first year of the vesting period and
then at a rate of 1/48 per month thereafter. Options will expire, if not
exercised, upon the earlier of 10 years from the date of grant or 90 days after
termination as an employee of the Company.

    In April of 1996, the Company granted options to purchase 120,000 shares of
Common Stock to a non-employee in exchange for services with an exercise price
of $0.0063 per share and which vested over a two year term. The value assigned
to these stock options by the Company was not significant during the year ended
June 30, 1996. In accordance with SFAS No. 123, the Company then remeasured

the valuation of these stock options annually over the vesting period. During
the year ended June 30, 1997, the incremental value assigned to these options
was not significant. During the year ended June 30, 1998, the incremental value
assigned to these stock options was $10,000 and was included as a component of
general and administrative expenses.

    During the years ended June 30, 1999 and 2000, in connection with the
granting of stock options to employees and members of the Board of Directors
with exercise prices subsequently determined to be below fair value, the Company
recorded deferred stock compensation aggregating $6,537,000 and $27,221,000,
respectively. These amounts are being amortized into expense over the vesting
period of the related options, generally four years using the method set out in
FASB Interpretation No. 28 ("FIN 28"). Under the FIN 28 method, each vested
tranche of options is accounted for as a separate option grant awarded for past
services. Accordingly, the compensation expense is recognized over the period
during which the services have been provided. This results is higher
compensation expense in the earlier vesting periods of the related options.
Amortization expense associated with deferred stock compensation totaled
$3,032,000 for the year ended June 30, 1999 and $12,740,000 for the year ended
June 30, 2000.

three years ended June 30, 2000 is set forth below:

infringement related to the manufacture and sale of fiber optic products which

for the year ended June 30, 2000. An unfavorable ruling in this matter would
have an adverse material impact on the Company's financial condition and
reported results of operations.

    In June 2000, a lawsuit was filed against the Company and Telelight
Communication Inc., alleging patent infringement relating to the manufacture of
and offer to sell various fiber optic products.

    In both lawsuits, the plaintiffs are seeking damages and injunctive relief.
The Company, with the assistance of counsel, intends to vigorously defend its
position in both matters. However, because of the considerable uncertainties
that exist, the impact, if any, on the Company cannot now be reasonably
estimated based on facts currently available to management. Accordingly, the
Company has determined that it would be inappropriate to book an accrual with
respect to these litigation matters in the consolidated financial statements.

NOTE 10--SEGMENT REPORTING:

    In 1998, the Company adopted FAS No. 131, "Disclosures About Segments of an
Enterprise and Related Information." SFAS No. 131 establishes standards for
reporting information about operating segments in annual financial statements
and requires selected information about operating segments in interim financial
reports issued to stockholders. Operating segments are defined as components of
an enterprise about which separate financial information is available that is
evaluated resources and in assessing performance.

    The Company has determined that it has one reportable segment: Fiber optic
components and module product sales. This segment consists of organizations
located in the United States and the People's Republic of China which develop,
manufacture, and/or market fiber optic networking components.

NOTE 11--401(k) PLAN:

    In 1997, the Company adopted a defined contribution retirement savings plan
under Section 401(k) of the Internal Revenue Code. This plan covers
substantially all employees who meet minimum age and service requirements and
allows participants to defer a portion of their annual compensation on a pretax
basis. All employees are eligible to participate three months after employment.
Matching contributions are at the discretion of the Company. The Company made no
matching contribution to the plan during three years ended June 30, 2000.

NOTE 12--PRO FORMA NET LOSS PER COMMON SHARE AND PRO FORMA STOCKHOLDERS' EQUITY:

    Upon the closing of the Company's initial public offering, all outstanding
Convertible Preferred Stock will be automatically converted into Common Stock.
The pro forma effect of this conversion has been presented as a separate column
in the Company's consolidated balance sheet, assuming the conversion had
occurred as of June 30, 2000. Pro forma basic and diluted net loss per common
share have been computed as described in Note 2 and also give effect to common
equivalent shares from preferred stock that will automatically convert upon the
closing of the Company's initial public offering (using the "as-if-converted
method") for the three years ended June 30, 2000.

2000 NON-EMPLOYEE DIRECTOR STOCK OPTION GRANTS

    In July 2000, the Company adopted the 2000 Equity Incentive Plan which
provides for the automatic grant of nonstatutory stock options to purchase
shares of common stock to its non-employee directors.

    AUTOMATIC GRANTS.  Upon the completion of this offering, beginning 2001, on
the day after its annual stockholders' meeting, any person who is then a
non-employee director and who is elected at such annual meeting will
automatically be granted an option to purchase 72,000 shares of common stock.
These grants will vest over a three-year period and will vest on a monthly
basis. Any non-employee director who is elected or appointed to the board during
a three-year term will automatically be granted an option to purchase a pro rata
portion of shares based on the number of months remaining in the term.

2000 EMPLOYEE STOCK PURCHASE PLAN

    In July 2000, our board of directors adopted the 2000 Employee Stock
Purchase Plan which authorizes the issuance of 4,000,000 shares of its common
stock pursuant to purchase rights granted to its employees or to employees of
any of its affiliates. The Company expects that the 2000 purchase plan will be
approved by its stockholders prior to completing this offering. The purchase
plan is intended to qualify as an employee stock purchase plan within the

employees may purchase its common stock through payroll deductions. As of the
date hereof, no shares of common stock have been purchased under the purchase
plan.

COMMON STOCK

    Subsequent to June 30, 2000, the Company issued shares and granted options
to purchase 4,826,700 shares of common stock at a weighted average exercise
price of $4.52 per share that will result in additional deferred stock
compensation of $21.8 million.

payable to Cisco Systems, Inc. The note payable accrues interest at a rate of 8%
per annum. Upon the closing of the Company's initial public offering, the note
payable and any unpaid accrued interest will be converted into shares of the
Company's Common Stock at a price per share equal to 85% of the initial public
offering price per share. Upon the closing of the Company's initial public
offering, the Company expects to record interest expense of $8.8 million,
representing the beneficial conversion feature of this note payable.

               UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

                                    OVERVIEW

    In February, 2000, Oplink Communications, Inc., ("Oplink" or the "Company")
entered into a definitive agreement to acquire Telelight Communication Inc.
("Telelight") in a merger transaction to be accounted for as a purchase business
combination. The acquisition was consummated April 6, 2000. The purchase price
comprised 13,440,000 shares of Common Stock valued at $26,880,000. The Company
also anticipates incurring approximately $200,000 in acquisition expenses,
including primarily legal fees and other direct transaction costs. The total
purchase price aggregated $27,080,000.

    The purchase price was allocated to the assets acquired, including tangible
and intangible assets, and liabilities assumed based upon the fair value of such
assets and liabilities on the date of the acquisition. The total estimated
purchase cost of the acquisition has been allocated to assets and liabilities
based on management's estimates of their fair value and an appraisal of certain
intangible assets with the excess costs over the net assets acquired allocated
to goodwill. The aggregate purchase price was allocated as follows (in
thousands):

    The net tangible assets of Telelight consist primarily of cash and cash
equivalents, accounts receivable, inventory, property and equipment, accounts
payable and other liabilities.

    The developed technologies acquired in the Telelight acquisition were the
Optical Circulator product and filter products. These products have yet to gain
market acceptance or receive certain industry-standard qualifications. Given
these facts and the commodity nature of these products, minimal value was
attributed to them in the purchase price allocation.

    The in-process research and development consisted of an Optical Wavelength
Interleaver product that, as of the date of acquisition, had not yet reached
technological feasibility and had no alternative future use. The Optical
Interleaver is a compact high performance fiber optic product that segments
optical signals by wavelengths. This product makes channel spacing smaller,
thereby increasing the number of channels on a fiber optic network.

    The value of the Optical Wavelength Interleaver was determined by estimating
the net cash flows from the sale of the products resulting from the completion
of this project, reduced by the portion of the net cash flows from the revenue
attributable to core technology. The resulting cash flows were then discounted
back to their present value using a discount rate of 35%. The fair value
assigned to the core technology totaled $6,245,000, and is being amortized over
the expected life of its cash flows of four years. At the time of the
acquisition this project was approximately 80% complete. The fair value assigned
to the in-process research and development totaled $7,020,000, and was charged
to expense at the time of the acquisition. The Company has incurred
approximately $50,000 of expense subsequent to

the acquisition, and in May 2000 the first qualified prototype was completed and
technological feasibility was achieved.

    The value of certain patents being assigned to Oplink was determined using
the relief from royalty methodology, which assumes that the value of the asset
equals the amount a third party would pay to use the asset and capitalize on the
related benefits of the assets. The fair value assigned to patents of $1,086,000
is being amortized over its expected life of four years.

    Goodwill is being amortized on a straight line basis of the estimated period
of benefit of four years.

               NOTES TO PRO FORMA COMBINED FINANCIAL INFORMATION

                                  (UNAUDITED)

    The following adjustments were applied to Oplink's historical financial
statements and those of Telelight to arrive at the pro forma combined financial
information.

(A) To record the amortization of identifiable intangible assets related to the
    acquisition of Telelight as if the transaction occurred on July 1, 1999.
    Identifiable intangible assets recorded in relation to the acquisition were
    approximately $7.4 million and are being amortized on a straight-line basis
    over four years.

(B) To record the amortization of goodwill related to the acquisition of
    Telelight as if the transaction occurred on July 1, 1999. Goodwill recorded
    in relation to the acquisition was approximately $14.6 million and is being
    amortized on a straight-line basis over four years.

(C) Weighted average shares used to calculate pro forma basic and diluted net
    loss per share for the period presented is computed using the weighted
    average number of Oplink Common Stock outstanding for the period presented,
    13,440,000 shares of Oplink Common Stock issued to the former shareholders
    of Telelight as if such shares were issued as of July 1, 1999 and also gives
    effect to common equivalent shares from preferred stock that will
    automatically convert upon the closing of the Company's initial public
    offering using the "as-if-converted" method.

(D) This adjustment removes the $7,020,000 write-off of in-process research and
    development because this charge is not expected to have a continuing impact
    on the Company.

                         NOTES TO FINANCIAL STATEMENTS

NOTE 1--THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

THE COMPANY

    Telelight Communication Inc. (the "Company") was incorporated in State of
California on April 20, 1998 for the purpose of developing and selling fiber
optic components and subsystems which are designed specifically to increase
capacity and bandwidth of fiber optic communications and data communication
networks. The Company is in the developmental stage and since inception, has
devoted substantially all of its time and efforts to developing products,
raising capital and recruiting personnel. As described in Note 5, the Company
was acquired by Oplink Communications, Inc. on April 6, 2000.

USE OF ESTIMATES

    The preparation of financial statements in conformity with accounting
principles generally accepted in the United States requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

INTERIM CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

    The interim consolidated financial statements at March 31, 2000 and for the
three months ended March 31, 1999 and 2000 are unaudited but, in the opinion of
management, has been prepared on the same basis as the annual consolidated
financial statements and include all adjustments (consisting only of normal
recurring adjustments) considered necessary for a fair presentation of its
financial position at such date and its operating results and cash flows for
those periods. Results for the interim period are not necessarily indicative of
the results to be expected for the entire year, or any future period.

REVENUE RECOGNITION

    Revenue from product sales is recognized upon shipment of the product or
customer acceptance, which ever is later. Provisions for estimated future
product returns are recognized upon product shipment.

CASH AND CASH EQUIVALENTS

    The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.

INVENTORY

    Inventory includes principally raw materials and is stated at the lower of
cost or market, cost being determined using the first-in-first-out FIFO
inventory method.

PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost less accumulated depreciation.
Depreciation is computed using the straight-line method over the estimated
useful lives of the related assets, generally five to seven years.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

NOTE 1--THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
RESEARCH AND DEVELOPMENT EXPENDITURES

    Costs related to research, design, and development of products are charged
to research and development expense as incurred.

STOCK-BASED COMPENSATION

    The Company accounts for stock-based employee compensation arrangements in
accordance with provisions of Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees," ("APB No. 25") and complies with the
disclosure provisions of Statement of Financial Accounting Standards No. 123,
"Accounting for Stock-Based Compensation" ("SFAS No. 123"). To date, no
stock-based compensation has been undertaken.

CONCENTRATIONS OF CREDIT RISK

    Financial instruments that potentially subject the Company to a
concentration of credit risk consist of cash and cash equivalents. The Company's
cash and cash equivalents are deposited with one major financial institution in
the United States. Deposits in this institution may exceed the amount of
insurance provided on such deposits. For financial instruments consisting of
cash and cash equivalents, other current assets, accounts payable, and accrued
liabilities included in the Company's financial statements, the carrying amounts
approximate fair value due to their short maturities.

IMPAIRMENT OF LONG-LIVED ASSETS

    The Company evaluates the recoverability of its long-lived assets in
accordance with Statement of Financial Accounting Standards ("SFAS") No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed of." SFAS No. 121 requires recognition of impairment of long-lived
assets in the event the net book value of such assets exceeds the future
undiscounted cash flows attributable to such assets.

RECENT ACCOUNTING PRONOUNCEMENTS

    In June 1998, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities." SFAS
No. 133 establishes new standards of accounting and reporting for derivative
instruments and hedging activities. SFAS No. 133 requires that all derivatives
be recognized at fair value in the statement of financial position, and that the
corresponding gains or losses be reported either in the statement of operations
or as a component of comprehensive income, depending on the type of hedging
relationship that exists. In July 1999, the FASB issued SFAS No. 137,
"Accounting for Derivative Instruments and Hedging Activities--Deferral of the
Effective Date of FASB Statement No. 133." SFAS No. 137 deferred the effective
date of SFAS No. 133 until fiscal years beginning after June 15, 2000.
Currently, the Company does not hold derivative instruments or engage in hedging
activities.

    In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin ("SAB") 101, "Revenue Recognition in Financial Statements."
SAB 101 provides guidance for revenue

recognition under certain circumstances. The Company has evaluated the impact of
SAB 101 and believes that it's adoption will not have a material impact on its
results of operations.

    At December 31, 1999, the Company had approximately $278,000 of federal and
$279,000 of state net operating loss carryforwards available to offset future
taxable income which expire in varying amounts beginning in 2018 and 2006,
respectively.

    The Company has research credit carryforwards of approximately $3,500 and
$3,000 for Federal and California income tax purposes, respectively. If not
utilized, the federal credit will expire in various amounts beginning in 2018.
The California research credit can be carried forward indefinitely.

    Under the Tax Reform Act of 1986, the amounts of and benefits from net
operating loss carryforwards may be impaired or limited in certain
circumstances. Events which cause limitations in the amount of net operating
losses that the Company may utilize in any one year include, but are not limited
to, a cumulative ownership change of more that 50%, as defined, over a three
year period.

    Future minimum lease payments under the noncancelable operating lease are
$37,240 in 2000.

</TABLE>

    The representatives have advised us that the underwriters propose to offer
the shares of common stock to the public at the public offering price set forth
on the cover page of this prospectus and to certain dealers at that price less a
concession of not in excess of $      per share, of which $      may be
reallowed to other dealers. After this offering, the public offering price,
concession and reallowance to dealers may be reduced by the representatives. No
such reduction shall change the amount of proceeds to be received by us as set
forth on the cover page of this prospectus. The common stock is offered by the
underwriters as stated herein, subject to receipt and acceptance by them and
subject to their right to reject any offer in whole or in part.

    Prior to this offering, there has been no public market for the common
stock. Consequently, the public offering price for the common stock offered by
this prospectus has been determined through negotiations among the
representatives and us. Among the factors considered in such negotiations were
prevailing market conditions, certain of our financial information, market
valuations of other companies that we and the representatives believe to be
comparable to us, estimates of our business potential, the present state of our
development and other factors deemed relevant.

    The underwriters have advised us that they do not expect sales to
discretionary accounts to exceed five percent of the total number of shares
offered.

OVER-ALLOTMENT OPTION


    We have granted to the underwriters an option, exercisable during the 30-day
period after the date of this prospectus, to purchase up to
2,055,000 additional shares of common stock to cover over-allotments, if any, at
the public offering price less the underwriting discount set forth on the cover
page of this prospectus. If the underwriters exercise their over-allotment
option to purchase any of the 2,055,000 additional shares of common stock, the
underwriters have severally agreed, subject to certain conditions, to purchase
approximately the same percentage thereof as the number of shares to be
purchased by each of them bears to the total number of shares of common stock
offered in this offering. If purchased, these additional shares will be sold by
the underwriters on the same terms as those on which the shares offered hereby
are being sold. We will be obligated, pursuant to the over-allotment option, to
sell shares to the underwriters to the extent the over-allotment option is
exercised. The underwriters may exercise the over-allotment option only to cover
over-allotments made in connection with the sale of the shares of common stock
offered in this offering.

INDEMNITY

    The underwriting agreement contains covenants of indemnity among the
underwriters and us against certain civil liabilities, including liabilities
under the Securities Act of 1933, and liabilities arising from breaches of
representations and warranties contained in the underwriting agreement.

LOCK-UP AGREEMENTS


    Each of our executive officers and directors and stockholders holding
approximately 94.8% of our common stock have agreed, subject to specified
exceptions, not to offer to sell, contract to sell, or otherwise sell, dispose
of, loan, pledge or grant any rights with respect to any shares of common stock
or any options or warrants to purchase any shares of common stock, or any
securities convertible into or exchangeable for shares of common stock owned as
of the date of this prospectus or thereafter acquired directly by those holders
or with respect to which they have the power of disposition, without the prior
written consent of FleetBoston Robertson Stephens Inc. This restriction
terminates after the close of trading of the shares on the 180th day of (and
including) the day the shares commenced trading on the Nasdaq National Market.
However, FleetBoston Robertson Stephens Inc. may, in its sole discretion and at
any time or from time to time before the termination of the 180-day period,
without notice, release all or any portion of the securities subject to lock-up
agreements. There are no existing agreements between the representatives and any
of our shareholders or optionholders who have executed a lock-up agreement
providing consent to the sale of shares prior to the expiration of the lock-up
period.


    In addition, we have agreed that during the lock-up period we will not,
without the prior written consent of FleetBoston Robertson Stephens Inc.,
subject to certain exceptions, consent to the disposition of any shares held by
shareholders subject to lock-up agreements prior to the expiration of the
lock-up period, or issue, sell, contract to sell, or otherwise dispose of, any
shares of common stock, any options or warrants to purchase any shares of common
stock or any securities convertible into, exercisable for or exchangeable for
shares of common stock other than our sale of shares in this offering, the
issuance of our common stock upon the exercise of outstanding options or
warrants, and the issuance of options under existing stock option and incentive
plans provided that those options do not vest prior to the expiration of the
lock-up period. See "Shares Eligible for Future Sale."

LISTING

    We have applied for the approval to list our common stock on the Nasdaq
National Market under the symbol "OPLK."

                [ALTERNATIVE PAGE FOR INTERNATIONAL PROSPECTUS]


SYNDICATE SHORT SALES



    The representatives have advised us that, on behalf of the underwriters,
they may make short sales of our common stock in connection with this offering,
resulting in the sale by the underwriters of a greater number of shares than
they are required to purchase pursuant to the underwriting agreement. The short
position resulting from those short sales will be deemed a "covered" short
position to the extent that it does not exceed the 2,055,000 shares subject to
the underwriters' over-allotment option and will be deemed a "naked" short
position to the extent that it exceeds that number. A naked short position is
more likely to be created if the underwriters are concerned that there may be
downward pressure on the trading price of the common stock in the open market
that could adversely affect investors who purchased shares in the offering. The
underwriters may reduce or close out their covered short position either by
exercising the over-allotment option or by purchasing shares in the open market.
In determining which of these alternatives to pursue, the underwriters will
consider the price at which shares are available for purchase in the open market
as compared to the price at which they may purchase shares through the
over-allotment option. Any "naked" short position will be closed out by
purchasing shares in the open market. Similar to the other stabilizing
transactions described below, open market purchases made by the underwriters to
cover all or a portion of their short position may have the effect of preventing
or retarding a decline in the market price of our common stock following this
offering. As a result, our common stock may trade at a price that is higher than
the price that otherwise might prevail in the open market.



STABILIZATION



    The representatives have advised us that, pursuant to Regulation M under the
Securities Exchange Act of 1934, they may engage in transactions, including
stabilizing bids or the imposition of penalty bids, that may have the effect of
stabilizing or maintaining the market price of the shares of common stock at a
level above that which might otherwise prevail in the open market. A
"stabilizing bid" is a bid for or the purchase of shares of common stock on
behalf of the underwriters for the purpose of fixing or maintaining the price of
the common stock. A "penalty bid" is an arrangement permitting the
representatives to claim the selling concession otherwise accruing to an
underwriter or syndicate member in connection with the offering if the common
stock originally sold by that underwriter or syndicate member is purchased by
the representatives in the open market pursuant to a stabilizing bid or to cover
all or part of a syndicate short position. The representatives have advised us
that stabilizing bids and open market purchases may be effected on the Nasdaq
National Market or otherwise and, if commenced, may be discontinued at any time.


DIRECTED SHARE PROGRAM

    At our request, certain of the underwriters have reserved up to
five percent of the shares of common stock for sale in this offering at the
initial public offering price to our directors, officers and employees and
persons who are otherwise associated with us. The number of shares of common
stock available for sale to the general public will be reduced to the extent
these individuals purchase reserved shares. Any reserved shares which are not
purchased will be offered by the underwriters on the same basis as the other
shares of common stock offered in this offering. We have agreed to indemnify
these underwriters against various liabilities and expenses, including
liabilities under the Securities Act of 1933, in connection with the sales of
directed shares.

ITEM 14. INDEMNIFICATION OF OFFICERS AND DIRECTORS.

    Section 145 of the Delaware General Corporation Law, permits indemnification
of officers, directors, and other corporate agents under certain circumstances
and subject to certain limitations. The Registrant's Articles and Bylaws provide
that the Registrant shall indemnify its directors, officers, employees and
agents to the full extent permitted by the Delaware General Corporation Law,
including circumstances in which indemnification is otherwise discretionary
under Delaware law. In addition, the Registrant has entered into separate
indemnification agreements with its directors and executive officers which
require the Registrant, among other things, to indemnify them against certain
liabilities which may arise by reason of their status or service (other than
liabilities arising from acts or omissions not in good faith or willful
misconduct).

    These indemnification provisions and the indemnification agreements entered
into between the Registrant and its executive officers and directors may be
sufficiently broad to permit indemnification of the Registrant's executive
officers and directors for liabilities (including reimbursement of expenses
incurred) arising under the Securities Act.

    The Underwriting Agreement to be filed as Exhibit 1.1 to this Registration
Statement provides for indemnification by the Underwriters of the Registrant and
its officers and directors for certain liabilities arising under the Securities
Act, or otherwise.

    All schedules are omitted because they are not required, they are not

ITEM 17. UNDERTAKINGS.

    The undersigned registrant hereby undertakes:

    (1) That for purposes of determining any liability under the Securities Act,
the information omitted from the form of this prospectus filed as part of this
Registration Statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
497(h) under the Securities Act shall be deemed to be part of this Registration
Statement as of the time it was declared effective.

    (2) That for purposes of determining any liability under the Securities Act,
each post-effective amendment that contains a form of prospectus shall be deemed
to be a new registration statement

                                      II-4
<PAGE>
relating to the securities offered therein, and the offering of the securities
at that time shall be deemed to be the initial bona fide offering thereof.

    (3) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions referenced in Item 15 of this Registration
Statement or otherwise, the Registrant has been advised that in the opinion of
the Securities and Exchange Commission this indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against these liabilities (other than
the payment by the Registrant of expenses incurred or paid by a director,
officer, or controlling person of the Registrant in the successful defense of
any action, suit or proceeding) is asserted by a director, officer, or
controlling person in connection with the securities being registered, the
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question of whether the indemnification by it is against public policy as
expressed in the Securities Act of 1933, and will be governed by the final
adjudication of this issue.

    (4) To provide to the Underwriters at the closing specified in the
Underwriting Agreement certificates in the denomination and registered in the
names required by the Underwriters to permit prompt delivery to each purchaser.
