For high-power transmission step-index multimode fibers areused. For most of them, undoped fused silica is chosen as corematerial, as it is suitable for high-power transmission suchas laser transmission due to its low attenuation level. Doped

improved launching of light into the fiber or

Stress elements

Polarization-maintaining fibers are special singlemode fibersthat maintain the polarization of the light in the fiber.
Stress elementsembedded in the cladding exert mechanicalstresses on the fiber core, which leads to birefringence in thefiber core.
The stress elements embedded can have different designs.
These fibers are used in networks with optical fibers, for pumplasers and for microscopic applications.

Fibers with rectangular shape ➔can improve the signal strength in fiber laser applications byminimizing the energy density decrease at the end of the fibercore. This decrease occurs in particular when the emitted poweris launched into a circular fiber from a rectangular solid statelaser. An improved coordination of dimensions and profiles enables the transmission of light by laser diodes with energy densities as needed for medical applications in particular.

Our low-OH multimode sensor fibers were developed especiallyfor data transmission with large bandwidths. They display
minimum spectral attenuation over a wide wavelength range
from 850 nm to 1400 nm. Provided with an optional 500 µm
coating, our sensor fibers are particularly suited for applications
under demanding environmental conditions. Optional hightemperature or polyimide coatings protect the fibers in hightemperature ranges. Phosphorus-free core material composi-

Info
An increase of up to 2 dB/km
in the fiber attenuation
value is to be expected
when fibers are combined
into cables.

03
Good mechanical protection is usually needed for using fibers
in a variety of different applications.
For smaller lengths (<200 m), we offer a range of different
protective tubes from the simple PVC tube to the costly metal
corrugated tube (Chapter 11 | Accessories from page 336).
The fibers are pulled into the tube. For longer lengths (>200 m)
it is possible to manufacture a cable.

Fiber optic bundles
Synthetic fused silica and optical glass

LEONI produces customer-specific fiber optic
bundles made from UV-conductive silica/silica(high-OH), IR-conductive silica/silica (low-OH),
plastic or optical glasses with different refractive
indices as appropriate to the requirement for the
optically conductive material on its own drawing
systems.

The fiber bundles are available specifically for endoscopic
applications in different radiation angles of 67° (LB type),
83° (LA type), 90° (LW2 type) and ≥100° (L120.3 type) for
optimum illumination. Our range also includes UV-resistant(solarisation-stable) silica/silica fibers. In addition to endoscopy, they are also used in spectrometry, lighting and sensor
technology.
The individual fibers are coated with glass finish (autoclavable

POF cables are divided into thefollowing fiber groups:

POF buffered fibers:
Step-index standard
Step-index POF low/high NA
Step-index high-temperature
Step-index for fast Ethernet
Graded-index

POF cables are available for indoors and outdoors. A wide
range of constructions are available depending on the requirement. Special requirements in terms of flexibility, resistanceto oil, resistance to UV, freedom from halogen or flame retardancy are met by selecting suitable components.

Info
Connectors for POF differ not onlyin terms of their construction, butalso in the technology used to attach
to the cable (crimping or clamping)and in the technology used to process
the end face. The focus here is on
lapping and polishing as well as hot
plate technology.

PCF
Polymer Cladded Fiber

Polymer cladded fibers (PCF) have been available
on the market for many years and are characterized by being very robust and easy to assemble.

LEONI uses a fiber with NA = 0.37, which shows especially low
attenuation at 650 and 850 nm, as its standard PCF. The low
attenuation makes it possible to bridge distances of up to 500 m
in systems designed for PCF with 650 nm and distances of up to
4 km in systems with 850 nm.

PCF consists of a glass core with polymer cladding. What is
especially important here is the good adhesion of the cladding

PCF cables and cable assemblies are suitable for a wide range

is mainly used in industrial automation as well as in the
Polymer cladding

Fusedsilica corecabling for wind-power and solar-power systems. It offers highmechanical resistance as well as cost-effective and direct connector assembly.
Transmission rates are constantly increasing in industrial
settings (up to 10 Gigabit Ethernet), which means that the bandwidth of the standard PCF is no longer sufficient at 15 MHz x km.
The bandwidth of optical fibers with step-index profile suchas standard PCF is drastically restricted by the modal dispersion. The use of gradient-index fibers is the best solution to thisproblem

ETFE buffer and gradient-index core is the ideal solution forcommunication applications that require high bandwidths inharsh industrial environments. The adapted PCF fiber design
has a positive influence on the fiber properties in terms ofservice life, mechanical resilience as well as higher moisture andtemperature resistance in comparison with standard multimodeglass fibers with 62.5 μm core.
The use of a polymer coating also enables connectors to be
crimped or clamped directly to the fibers for quick and efficient
assembly in the field.

Fiber specifications

For our extensive range of cables we resort to all standardised
fibers from the IEC series, the ISO series or the ITU-T series.

09

Both singlemode fibers (E9/125) as well as multimode fibers(G50/125, G62.5/125 and G100/125) are available in conventional and bend insensitive quality for this purpose.
If desired, we can also offer radiation hard fibers andspecial fibers.

1) UV resistance can be increased byadding black colour pigments or UV
stabilisers
2) Permeation depends on the type of gas
e.g. Ar, CH4, N2, O2 low gas permeation;
CO2, H2, He higher gas permeation
3) low swelling in saturated hydrocarbons; significant swelling in aromatichydrocarbons, aliphatic esters causeswelling, highly polar organic solvents
dissolve under underuchpolare
4) Swelling in aliphatic and aromatichydrocarbons and chlorinated hydro­

Note: instead of FRNC (flame retardant non corrosive),
often the expression LSOH or LSZH (low smoke zero halogen)or HFFR (halogen free flame retardant) is used.

This design is therefore especially suited as a longitudinallywatertight optical universal cable for mobile use for constantreeling in and out as well as in drag chains. The cross-linked
gel retains its consistency even at high temperatures, thereby
preventing the gel leaking out when dealing with installation
distances with big drops or with vertical installation.
Splice trays filling up with gel and sagging fibers are
therefore a thing of the past.

tested and certified in accordance with valid standards. In
shipbuilding in particular, the reliable interaction of many
components is of crucial importance for trouble-free operation.
It is also vital in the event of fire to be able to rely on the function of the fiber optic cables for a verified period (functional

Description

Application

The new multimode splitter series is based on planar integrated■■

Laser applications

waveguides which are produced by means of ion exchange in■■

Measuring techniquesglass. The multimode components are based exclusively on■■

Sensor technology

monolithic integrated, lithographically patterned waveguides.

Note for measurements with POF buffered fibers Ø 2.2 mm
without connector:
The fiber ends of the POF buffered fibers to be measured
must be cleanly cut (e.g. using the POF fiber cutter ZXXX-TD0V2). The SMA 2.2 mm clamp connectors SSMA-SV0-02-0020 must be
attached to the prepared fiber ends in such a way that the end faceof the connector is flush with the ferrule. The buffered fibers“assembled” in this way can now be measured using the meter (withFSMA adapter) and the connectors can then be removed again.

For this the transmitter should have the same radiation charac­
teristics as in the application. The method is described in theIEC 60793-1-40. To minimise the influence of the transmitter, it
is possible to work with a launching length, in which a mode
scrambler generates a defined ray distribution in the fiber(IEC 61300-3-4 method B). The attenuation effect of the lastconnector is suppressed using these two methods. By contrast,
if a lead-in and a lead-out length are used, as specified in
IEC 61300-3-4 method C, the entire cable is tested by means of
one single measurement. The different test set-ups can result indifferent values in the order of up to approx. 2 dB, depending on
the type of fiber and connector.

2.1.3.2 Direct-light measurement
With the direct-light technique, an optical waveguide with alength L [m] is connected to a light source having a defined
wavelength of power P0 [dBm]. The optical power P1 [dBm] atthe end of the optical waveguide is then measured using a
power meter. The power loss, i.e. the optical attenuation A [dB],is calculated from the difference between P0 and P1 :a = P0 – P1 [2-7]
If the path attenuation is much greater than the connector loss,
the attenuation coefficient α [dB/m] can be calculated as follows:
α = a/L = ( P0 – P1)/L [2-8]The insertion loss method or cut-back method is usually used
for measuring the optical power. The various techniques of theinsertion loss method are targeted at specific applications or
quality criteria. With patch cables that are connected directly
to the transmitter and receiver, it is generally only necessary tocompare these cables with a good reference cable of the same
fiber, with the absorption value being calculated as follows

Temperature and moisture induce defects in plastic opticalfibers, which manifest themselves through a rise in attenuation.
With POF, the increase in absorption has been proven throughthe accumulation of OH ions, which causes an increase in attenuation as a function of the wavelength. Statistical statements

F1

Method F1: Temperature cycling
This test procedure examines the stability of fiber attenuation ofa fiber optic cable over the permitted temperature range for its
particular use and also for its storage and transport.
Because of the different coefficients of expansion of the structural cable materials as well as certain shrinkage effects of theplastics under thermal stress, the fibers are subjected to com­pres­sion or tensile stress which can cause considerable increases
in attenuation if the cable design is not ideal.
The test is usually carried out in a large temperature chamber
on an entire factory length as a loose coil or wound up on a reel(see fig. 22 top). Loose coils are preferred where possible, as thisavoids the influences due to the coefficients of expansion of thereel. In practice, however, with rather thick cables it is often notpossible to wind suitably long lengths as a loose coil.

is moved into the beam path using a piezo bender, the widened
beam is correspondingly shifted into a parallel path and guided
into a different output fiber. Up to four beam shifting elements
can be combined in this kind of switch design, addressing up to

3.2 Fiber optic probes for ophthalmic surgery
These days many surgeries for eye diseases are executed withthe help of lasers. A distinction is made between surgeries atthe surface and inside the eye. With surgical interventions inside
the eye in particular the laser light has to be guided close to theaffected area. This can be for example the retina or macula in
the back of the eye. Surgery inside the eye is called vitrectomy.
Lasers with the wavelengths 532 nm, 577 nm or 810 nm are suitedfor intraocular interventions. For transscleral applications (using
a suited cannula inserted through the sclera) a diode laser with
810 nm is required.
With the help of optical fibers the light energy needed for
cutting and coagulating damaged tissue can be guided to theaffected area inside the eye with pinpoint precision (laser spot).
As the glass fiber itself does not have the afforded mechanicalstability, handpieces are needed in which the fiber is fixed

Principles

Definition of terms
Term

Definition

Absorption

Loss of light radiation when passing throughmatter as the result of conversion into other formsof energy, e.g. heat energy. With photodiodes, theabsorption is the process that destroys a photon
as it arrives and through its energy elevates anelectron from the valence band to the conduction
band.

Acceptance angle

The largest possible angle within which lightin the area of the fiber core can impinge on theend face, thus enabling it to be guided along thefiber core.

Add-Drop-Multiplexer

Functional module that makes it possible to
add and drop partial signals to/from a multiplex
signal.

Amplified spontaneousemission

Amplification of spontaneous events in an opticalamplifier when the input signal is missing. Causes
the characteristic noise of the fiber amplifier.

AnalyserComponent for checking the state of polarisationof the light. Differs from a polariser only withregard to its function in the selected opticaldesign. The analyser is located on the observerside.

Bandwidth of the opticalamplifierSpectral range that is optically amplified (usuallybased on a 3-dB drop).

Bandwidth-length
product

The bandwidth of an optical fiber is approximately inversely proportional to its length withnegligible mode mixing and changing processes.
The bandwidth multiplied by the length is therefore almost constant. The BLP is an importantparameter for characterising the transmission
properties of multimode fibers. With increasing
length, the bandwidth decreases to a lesser
extent. Consequently, a modified relationshipapplies to the BLP, in which a gamma factor isintroduced.

Bend loss

Additional loss caused by micro- or macro-bending. An increased bend loss may be caused by
the manufacture of the cable or by poor cablerouting.

Bending radius

Two different definitions:
1. Minimum radius of curvature by which a fiber
can be bent without breaking. 2. Minimum radiusof curvature by which a fiber can be bent without
exceeding a certain predetermined attenuation
value.

Bidirectional

Propagation of optical signals in opposing directions along one optical waveguide.

Birefringence

Property by which the effective propagation
velocity of the light wave in a medium depends
on the orientation of the light’s electrical field(state of polarisation).

Bit

Basic unit of information in digital transmission
systems. The bit is equivalent to the decision
between two states, 1 and 0. Bits are represented
as pulses. A group of eight bits is equal to one
byte.

Bit error rate

The ratio of the number of bit errors occurring
on average in digital signal transmission over a
relatively long period of time to the number ofbits transmitted during this period. The bit error
rate is a system-specific index of error probability.
The standard requirement is a BER < 10–9. In
modern SDH systems, a BER < 10–12 is required.
The bit error rate can be reduced using forward
error correction (FEC).

APC connector➔ HRL connector

Arrayed waveguidegrating

Integrated, optical component that functions
as a multiplexer/demultiplexer. Different input
wavelengths cause differences in phase, permitting a channel separation similar to the classic
diffraction grating.

Attenuation

Reduction in the optical signal power in a fiber
due to scattering, absorption, mode conversion
or at a coupling point (connector, splice). Attenuation is a dimensionless variable and is usually
given in decibels.

Attenuation coefficient

Is the attenuation based on the length of thefiber. The attenuation coefficient is expressed in
dB/km and is an important parameter for characterising a fiber.

Attenuation dead zone

Minimum spacing from a reflecting event in order
to be able to measure the attenuation of a following event (OTDR measurement).

Attenuation-limited
operation

Limitation of the achievable transmission link due
to the effects of attenuation.

Bit rate

Transmission rate of a binary signal, also called
the bit repetition rate.

Avalanche photodiodeReceiver component that is based on the avalanche effect: the photoelectric current is amplified through carrier multiplication.

CCDR

Cladding-to-core diameter ratio

Channel gain

The amplification of a signal with a specific wavelength in a DWDM system. It differs in generalfor different wavelengths.

Channel spacing

Frequency spacing or wavelength spacing
between adjacent channels in a wavelength division multiplex system.

Chirp

Change in frequency (change in wavelength)of the laser diode as the result of modulation
across the laser current.

Backscatter attenuation

12
Band gap

Ratio of incident optical power to the opticalpower scattered in the fiber, this optical power
being capable of propagating in the reverse
direction. Usually expressed in decibels (positive
values).
Energy gap between the valence band and the
conduction band of a semiconductor. The band
gap defines the operating wavelength of a semiconductor laser.

Optical adapter that creates a gradual transition
from one optical waveguide to another.

Threshold current

The minimum current at which the amplificationof the light wave in a laser diode is greater thanthe optical losses, with the result that stimulated
emission starts. The threshold current is greatly
dependent on the temperature.

Time division multiplex

Multiplex system in which the time on one transmission channel is assigned to different sub-channels in succession.

Total internal reflection

Reflection at the boundary between a more
optically dense medium and a less optically dense
medium, the light propagating in the more optically dense medium. The angle of incidence at theboundary must be greater than the critical angleof total internal reflection.

TransceiverCompact component having one electricaland two optical interfaces (transmitter andreceiver). Contains an optical transmitter(e.g. laser diode) with an exciter for operating
the light source and an optical receiver(e.g. PIN diode) with a receiver circuit for operating the diode.

Transmission

Light transmission in the fiber as a percentage
based on the injected power.

Transmitter

A component in optical communications for converting electrical signals into optical signals.
The transmitter comprises a transmitter diode(laser diode or LED), an amplifier as well as otherelectronic circuits. For laser diodes in particular,a monitor photodiode with an automatic gain
control amplifier is required to monitor andstabilise the radiated power. A thermistor andPeltier cooling are often used to help stabilise the
Operating temp..

Transponder

Wavelength converter (O/E/O converter). Implements the wavelength conversion and 2R or 3R
regeneration.

Tunable Laser

Laser that is able to change its peak intensity
wavelength to optimise it for any given application.

Unidirectional

Propagation of optical signals in the same direction along one fiber.

Uniform mode distribution

Mode distribution in which the power is distributed uniformly across all modes.

Uniformity

Difference in insertion losses from the best andworst ports (in decibels) with multi-port couplers

V numberDimensionless parameter that is dependent
on the core radius, the numerical apertureand the wavelength of the light. The number ofguided modes is determined by the V number.

Water peak

Increase in attenuation of the fiber in the regionof the wavelength of 1383 nm caused by hydroxyl
ion impurities in the glass.

Waveguide

A dielectric or conductive medium in which electromagnetic waves can propagate.

Waveguide dispersion

Typical type of dispersion in a singlemode fiber.
Is caused by the wavelength dependence of thelight distribution of the fundamental mode on thecore and cladding glass.

Wavelength

Spatial period of a flat wave, i.e. the lengthof one complete oscillation. In optical communications, the wavelengths used are in the range
from 650 nm to 1625 nm. Velocity of light (in theparticular medium) divided by the frequency.

Wavelength divisionmultiplex

Method for increasing the transmission capacityof a fiber by simultaneously transmitting different
light wavelengths.

Zero-dispersion wavelength

Wavelength at which the chromatic dispersionof the fiber is zero.

Our top priority when manufacturing our medical products is toensure compliance with the fundamental requirements of
RL 93 / 42 / EEC and thus the safety of patients, users, third parties and the environment. This is documented by the CE marking
on our medical products. CE mark approval is verified every year
by our notified body.
To this end, we have implemented a comprehensive QA system
in line with the requirements of EN ISO 13585. This standard
contains the same basic requirements as EN ISO 9001, but also
goes a lot further.
