Fibre Optic
Connectors
5Dear Customers,
As far as data transmission is concerned, the superior characteristics of fibre optics compared to electrical cables are clearly recognised today.
The advantages of fibre optics include a transmission capacity 10 times greater than that of conventional
coaxial cables, in only one tenth of the size. The reduced weight and space requirements make handlingand line installation much easier. Furthermore, fibre optics is characterized by low signal amplitude loss,
no susceptibility to electromagnetic interference, and an absence of interference between neighbouringlines. It also offers greater security due to the difficulty of intercepting optical signals.
The growing number of applications is more and more varied, and the annual growth rate of fibre optics
is greater than 10%. Current applications of fibre optics include: telemetry, process control, data transmission, cable and closed circuit television, as well as laser signal transmission in medical applications.
However, most systems equipped with fibre optics also require simultaneous electrical energy for control
operations and power supply. Current practice involves the use of separate electrical and fibre optic
connectors.
The new technology developed by LEMO greatly simplifies this practice by combining electrical and fibre
optic signals in a single connector.
LEMO can now offer you a full range of mixed electrical/fibre optic connectors for singlemode or multimode transmission. This product range is available with metal or plastic outer shells, as well as in awatertight version.
The range is completed by the addition of a single channel fibre optic connector series. All LEMO fibre
optic connectors use a plug and socket push-pull self-latching connection system, obviating the need forplug to plug adaptors. This is a major advantage of the LEMO technology over its competitors.
With the aim of providing the best possible answers to your fibre optic needs, LEMO has establishedan important research and development facility to provide quick and effective solutions to your design
requirements.
LEMO ISO 9001 certified has been improving its “quality culture” with the aim of reaching TQM. Offeringzero defect products with due regard to the environment and meeting delivery requirements, are LEMO’s
two main concerns.

LEMO’s Push-Pull Self-Latching Connection System
This self-latching system is renowned worldwide for its easy and quick mating and unmating features. It provides absolute
security against vibration, shock or pull on the cable, and facilitates operation in a very limited space.

The LEMO Push-Pull self-latching system allows
the connector to be mated by simply pushing
the plug axially into socket.

Once firmly latched, connection cannot be broken
by pulling on the cable or any other component
part other than the outer release sleeve.

When required, the connector is disengaged
by a single axial pull on the outer release sleeve.
This first disengages the latches and then withdraws
the plug from the socket.

Introduction

The 00 Series
The characteristic feature of this connector series is thesmall size requiring minimum mounting space requirement.
Connectors are suitable for use with single fibre cables
fitted with single-mode or multi-mode fibres.
The 0B Series
A simple and proven construction with ceramic or metallic ferrules in a fibre optic contact primarily intended foruse with large size multi-mode fibres ranging from 140 to1500 micron external diameters.
The 0K SeriesThis series is watertight (IEC 60529/IP 66-IP 68) and isideal for use in harsh environments.
It uses the standard LEMO F2 fibre optic contact which
has undergone extensive mechanical, optical and environmental testing.
Connectors are suitable for use with single fibre cables
fitted with single-mode or multi-mode fibres.

Propagation of Light and Fibre TypeThe diagrams show the typical transmission characteristic of single-mode and multi-mode fibres.
In multi-mode fibres, the effect of modal dispersion
causes a spread in the received pulse and therefore
limits the bandwidth of the transmission system (Fig. 1).
If the fibre core is < 10 µm and the wavelength is ≥ 1300
nm, then only the fundamental mode is transmitted in the
single-mode fibre (Fig. 2).
The dispersion effects of single-mode fibres are verysmall and consequently they offer higher bandwidths
when compared with multi-mode fibres. However, multi-mode fibres are usually ideal for short distance applications because they require less input optical power andcan be driven by simple low cost LEDs.

The 1K to 5K SeriesThis product family includes the 1K to 5K series, and arewatertight (IEC 60529/IP 66-IP 68) available in the sametypes as the 1B to 5B series. The connectors are ideal foruse in harsh environments.
The video HDTV 3K.93C SeriesThis range of high performance fibre optic camera
connectors has been developed to meet the needs of the
new generation of digital TV cameras. Contact configuration includes 2 fibre optic contacts for single-mode fibres,
2 electrical contacts for power and 2 electrical contacts
for signal. This series conforms to the Japanese ARIB
technical report BTA S-1005B, to the ANSI/SMPTE 304
M-1998 and 311M-1998 standards and to the European
EBU Technical Recommendation R100-1999.
Connectors are qualified for use in UL approved equipment such as those specified in UL 1419 «Professional
Video and Audio Equipment»
CE marking
CE marking

General Characteristics
Selection of the LEMO Fibre Optic Contacts

In order to ensure the highest technical performance and to provide the optimum solution for a diversity of applications,
LEMO has developed four types of fibre optic contacts; designated F1, F2, F3, and F4. These contacts are designed tooperate with single fibre, multi fibre, and hybrid fibre optical/electrical cable constructions and cater to single and multi-mode fibres from 9/125 to 1500 µm diameter.
The choice of fibre optic contacts depends upon the following criteria:– Cable construction (single fibre, multi fibre, hybrid optical/electrical)– Fibre type (single-mode or multi-mode).
The table below shows the suitability of each contact type with different fibres and cables.
Note that the multi fibre cable can contain many types of optic fibres or a group of fibres and electrical cables leading tohybrid optical/electrical connectors.

00 Series
The 00 series connectors are fitted with LEMO F4 type fibre optic contacts.
The main features of this series are as follows:– Security of the LEMO Push-Pull self-latching system– Minimum mounting space requirement (high packing density)– Protection against accidental contamination or damage to the fibre end face because the ferrules do not protrude outside of the connector shell– The alignment key (G, B) ensures excellent repeatability of performance during frequent matings– Assembly of the fibre optic contact uses a ceramic ferrule with spherical end face
– Simple and fast polishing ensuring the physical contact of the fibre end face
– The alignment tube can be easily removed in order to clean the fibre end face.
00 Series consists of nine connector models.
The active device housings are designed to accept emitting or receiving components such as LEDs or photodiodes in a
TO-18 case.
The plugs and sockets are suitable for use with single fibre cables fitted with single-mode or multi-mode fibres of thefollowing dimensions; 9/125, 50/125, 62.5/125, 100/125 and 100/140 µm.

0K Series
The LEMO 0K series fibre optic connector is ideal for use in harsh environments. The mated connectors are sealed to
IP 66-IP 68 (underwater immersion to 1.5 m depth). It uses the standard LEMO F2 fibre optic contact which has undergone extensive mechanical, optical and environmental testing and has seen service in many critical applications such as
outside broadcast television.
Based upon the proven LEMO Push-Pull self-latching system, this new fibre optic connector features:– Sealed to IP 66-IP 68 for environmental protection– Highly compact design for space saving– Very low insertion loss for both multi-mode and single-mode fibres– Low back reflection performance– The alignment key (G, A…F) ensures excellent repeatibility of performance during frequent matings– Fully floating ceramic ferrule with spherical end face
– Simple and fast polishing ensuring the physical contact of the fibre end face
– The alignment tube can be easily removed in order to clean the fibre end face
– Field termination possible– Excellent shock and vibration resistance.

2B-5B Series
The 2B-5B connectors have been designed to work with the LEMO F1 or F2 type fibre optic contacts.
The main features of these series are as follows:– Security of the LEMO Push-Pull self-latching system– Protection against accidental contamination or damage to the fibre end face because the ferrules are recessed within
the connector shell­– The alignment key (G, A…L, Y and R) ensures excellent repeatability of performance during frequent matings– A choice of configurations of multi fibre or hybrid optical/electrical contacts.
The 2B-5B series consist of fifteen models. The possible outer cable diameters range from 1.5 to 25 mm.
Depending upon the type of fibre optic contact chosen, the connectors can accommodate single-mode fibres in Si/Si
9/125 or multi-mode fibres in silica or plastic with an external diameter up to 1500 µm.

Connectors are delivered without fibre optic contacts, therefore they must be ordered separately according to
the size and type of fibre (see pages 77 and 79). In case of hybrid with coax contacts type C, connectors aredelivered without the coax contact. See page 58 for ordering.
Note: 1) The «Variant» position in the reference is used to specify either the presence of a collet nut for fitting the bend relief, or the anodized colour ofthe housing in aluminium alloy. For models with collet nut for fitting the bend relief, a «Z» should be indicated and a bend relief can be ordered separately as indicated in the «Accessories» section. An order for a connector with bend relief should thus include two part numbers.
For the various housings available in colours, the corresponding letter in the part number for the colour is indicated on page 61.

2K-5K Series
The 2K-5K series connectors are designed to work with the LEMO F1 or F2 fibre optic contacts.
The main features of these series are as follows:– Security of the LEMO Push-Pull self-latching system– Specially designed for outdoors applications. All these models are waterproof when mated and reach a protection
index of IP66-IP68, according to the IEC 60529 standard– Protection against accidental contamination or damage to the fibre end face because the ferrules are recessed within
the connector shell– The alignment key (G, A…F, L and R) ensures excellent repeatability of performance during frequent matings– A choice of configurations of multi fibre or hybrid optical/electrical contacts.
The 2K-5K series consists of ten models which will accept outer cable diameters ranging from 3.6 mm to 23.5 mm.
Depending upon the type of fibre optic contact chosen, the connectors can accommodate single-mode fibres in Si/Si
9/125 or multi-mode fibres in silica or plastic with dimensions reaching 1500 µm.

Connectors are delivered without fibre optic contacts, therefore they must be ordered separately according to
the size and type of fibre (see pages 77 and 79). In case of hybrid (with coax contacts type C), connectors aredelivered without the coax contact. See page 58 for ordering.
Note: 1) The «Variant» position in the reference is used to indicate the presence of a collet nut for fitting the bend relief.
For models with the «T» type of cable adapter the «Z» should always be indicated and a bend relief can be ordered separately as indicated in the«Accessories» section. An order for a connector with bend relief should thus include two part numbers.

The fibre optic contacts must be ordered separately (see page 79).
Note: 1) The «Variant» position in the reference is used to indicate the presence of a collet nut for fitting the bend relief.
For models with the «T» type of cable adapter the «Z» should always be indicated and a bend relief can be ordered separately as indicated in the«Accessories» section. An order for a connector with bend relief should thus include two part numbers.

F2 Fibre Optic Contact
Introduction
The F2 type contact is designed for fitting into single fibre 0K series, multi fibre connectors or hybrid fibre optical/electrical connectors from 2B to 5B, 2K to 5K series.
Its main features are as follows:– Assembly uses pre-domed ceramic ferrules– Simple and fast polishing ensuring the physical contact of the fibre end face
– After mounting on the cable, the contact is very easily installed in the main connector insulator, the particular shape ofthe contact body retains it in the insulator– Unique cable assembly independent of the connector shell– The alignment tube can be easily removed in order to clean the fibre end face.
This contact makes it possible to use single fibre cables with single-mode or multi-mode fibres of the following sizes;
9/125, 50/125, 62.5/125, 100/125 and 100/140 µm.

Insertion and Extraction of the Fibre Optic Contacts
Cable Termination
Detailed instructions for terminating single fibre cables with LEMO F2 fibre optic contacts are given in the reference
manual DOC.FO.CF2.0000 supplied with the complete termination workstation (see page 103). After termination
contacts shall be introduced in the main insulator as shown below. For purpose of cleaning they can also be removed.

Insertion and Extraction of the F1 Type Contact
Insertion

Extraction

The fibre optic contact, male or female, terminated on thecable, must be inserted into the connector insulator fromthe back end until it comes to a stop (step 1 and 2).
Check that the contact is correctly retained by gently pulling on it (step 3).

Introduce the extractor, reference DCC.91.312.5LA (seepage 105), in the insulator around the contact and push
until it comes to a stop (step 1 and 2). Gently remove thefibre optic contact by pulling on the cable (step 3).

Extraction

The male fibre optic contact terminated on the cable must
be inserted into the connector insulator from the back end
until it comes to a stop. Make sure that the contact is correctly positioned into the inner antirotation key. Key is inline with the red dot on the rear of the contact (step 1).
Check that the contact is correctly retained by gently pulling on it (step 2).
For female contacts, the alignment device shall be clipped
onto the fibre optic contacts which is already fitted into
female insulator. This procedure is performed using the alignment device, reference DCS.F2.035.PN. The alignment
device shall be first installed onto threaded end of the alignment device (step 3). Then clip the adapter (step 4),
unscrew and remove the alignment device (step 5).

Reverse the order of the operation previously described.
For female contact remove first the alignment device.
Screw the threaded end of the alignment device reference,
DCS.F2.035.PN (step 1), onto the alignment device andpull out strongly (step 2).
Then use the extractor reference, DCC.91.312.5LA, introduce it into the insulator and push until it comes to a stop
to compress the contact body (step 3 and 4).
Gently remove the fibre optic contact by pulling on thecable (step 5).

Technical characteristics

Outer shellBrass
In most cases, LEMO connectors have a brass outershell which is suitable for most general purpose applications, including civilian and military. The brass outershells have a chrome nickel-plated surface which
ensures very good protection against industrial atmosphere, salt air and most corrosive agents.
Alternative protective coatings are available to satisfy
other specific environmental conditions:­– electrolytic nickel– nickel-black chrome. After the black chrome treatment, the part is coated with a protective organic film.
Stainless steel
For applications where there are severe environmental
conditions that may rapidly damage the surface finish,
we recommend using stainless steel. The AISI 303 stainless steel is a material for general use adapted to mostapplications requir­ing a product made entirely of stainless metal.
For the broadcasting industry the heavy duty line withshell in stainless steel offers more resistance to heavy
wear conditions.
Aluminium alloy
The aluminium alloy outer shells find numerous applications where light weight is a predominant factor, such as
in the aeronautics and space industries, and for portable
and mobile equipment.
These materials have high mechanical strength andexcellent resistance to corrosion.

The shell surface is protected by anodizing which is available in six colours: blue, yellow, black, red, green, andnatural.
Depending on the application, other surface finish is alsoavailable (electrolytic nickel-plating, black nickel plating).
Plastic materials
Some connector model shells of the 2B-4B series can bemade of plastic. This solution offers optimum electricalinsulating properties particularly suitable for medical
applications.
Grey or white polysulfone (PSU) and beige PEEK offer
excellent mechanical properties and is suitable for gas orvapour sterilization.
Some models are also available with an outer shell of
cream-coloured polyphenylsulfone (PPSU). We recommend this material particularly for applications where
products are to withstand hundreds of vapour sterilization cycles.
Other metallic components
In general, most metallic components are manufactured
in brass. However, bronze or beryllium copper are used
where good elasticity is required (for example: grounding
crown). Depending on the application, these parts haveelectrolytic nickel or nickel-gold plating. These parts canalso be manufactured in stainless steel (AISI 416).
Gasket and O-rings
In general, gaskets and O-rings are made of silicone
rubber MQ/MVQ. However, for some products they are
made of fluorosilicone rubber (FPM).

Insulator
LEMO uses PEEK (Polyether Etherketone) for the insulator material. The performance of this thermoplastic
material is enhanced by the addition of glass fibres in theresin to achieve very high mechanical strength, to108

increase dielectric strength and to reduce water absorption rate. The above features of PEEK plus its excellent
radiation resistance makes it ideal for most applications.
(See technical characteristics on page 107)®

Fibre Optic Contacts
In order to ensure the highest technical performance and to provide the optimal solution for a diversity of applications,
LEMO has developed the 4 types of fibre optic contacts designated F1, F2, F3, and F4.
F2 and F4 contacts are designed with fully floating pre-domed ceramic ferrule. Such contacts are mainly designed tooperate with single-mode and multi-mode fibres with small core dimensions.
F1 and F3 contacts are using floating metallic or ceramic ferrules. They are ideal for use with multi-mode, silica or plastic
fibres with large core diameters.

Optical Performance for F1, F2, F3, and F4 Type Contacts
The optical performance for the fibre optic contacts relates to the insertion and return losses measured at the junction of thefibre to fibre interface. These losses are caused mainly by minute geometrical effects of the critical alignment components
and deviations in the fibre core and cladding dimensions.
The insertion loss results for multi-mode and single-mode fibres are given whereas the return loss values are provided forsingle-mode fibres only.
Insertion and return losses are expressed in decibels (dB). The data shown in the diagrams below correspond to numerous
matings using various batches of optical fibres and connectors.

Electrical Contact
Technical description
The secure reliable electromechanical connection achieved
with LEMO female cylindrical contacts is mainly due to two
important design features:
1. Prod proof entry on the mating side which ensures perfect concentric mating even with carelessly handledconnectors; and2. The pressure spring, with good elasticity, maintains a
constant even force on the male contact when mated.
The leading edge of the pressure spring preserves thesurface treatment (gold-plated) and prevents undue wear.
Contact material and treatment
LEMO female contacts are made of bronze (UNS C
54400). This material is chosen because of its highmodulus of elasticity, its excellent electrical conductivity
and a high mechanical strength.

LEMO male solder contacts are made of brass (UNS C
38500). Male crimp contacts are made of brass (UNS C
34500) or annealed brass (UNS C 38500) with optimum
hardness (HV) for crimping onto the wire.

Solder contacts
The conductor bucket of these contacts is machined at
an angle to form a cup into which the solder can flow.
See page 9 for the range of cable dimensions that can besoldered.
Crimp contacts

Advantages of crimping

For multipole or hybrid connectors the standard fouridenter crimp method is used (MIL-C-22520F, class I,
type 1).
The crimp method requires a controlled compression to
obtain a symmetrical deformation of the conductor strand
and of the contact material. The radial hole in the side of
the contact makes it possible to check whether the
conductor is correctly positioned within the contact. A
good crimping is characterized by only slightly reduced
conductor section and practically no gap.

– practical, quick contact fixing outside the insulator– possible use at high temperature– no risk of heating the insulator during the conductorcontact fixing– high tensile strength

For optimum crimping, the bronze or brass contacts areannealed to relieve internal stress and reduce material
hardening during the crimping process.
Only the crimping zone is annealed with the help of an
induction heating machine designed by the LEMO
Research and Development Department.

Crimp contacts are available in standard version for
mounting maximum size conductors.
For some dimensions, these crimp contacts can be produced with reduced crimp barrels for mounting reduced
size conductors. Consult the factory for information.
The range of cable dimensions that can be crimped into
the contacts is indicated on the table on page 9.

Coaxial contacts type C
The cable fixing is achieved with hexagonal crimping(MIL-C-22520F, type 2). This method guarantees a goodelectrical continuity of the shield which improves greatly
the shielding efficiency of the cable/connector link. The
back end of the crimp nut which receives the shield braid,
is milled to ensure a good retention of the shield once
crimped.
For the center contact, square form crimp method isused (MIL-C-22520F, type 2). The method requires acontrolled compression to obtain a symmetrical deformation of the conductor strand and of the contact material.
Technical characteristics

The radial hole in the side of the contact enables correct
positioning of the conductor within the contact to be verified. A good crimping is characterized by a small
conductor section reduction and by the quite closed freespaces.
The LEMO crimp contacts are factory annealed to relieveinternal stresses, and reduce the risk of the material work
hardening during the crimping process.

Test voltage
Test voltage (Ue) :(measured according to the IEC 60512-2 test 4a standard)
It corresponds to 75% of the mean breakdown voltage.
Test voltage is applied at 500 V/s and the test duration is
1 minute.
This test has been carried out with a mated plug andsocket, with power supply only on the plug end.
The operating voltage value definition is at the entire
responsibility of the customer who defines this value
according to the safety factors that they apply to theirequipment and system.

Voltage values are given in the table on insulator types
for each series. They correspond with values measured
at sea level. They are adapted to all applications up to an
altitude of 2000 m.
In case a device is used at a higher altitude, air clearance
between live parts has to be multiplied by the following
coefficients.
It means also that test voltage has to be divided by thiscoefficient.

2. HANDLING
Connectors and their components should be visually inspected for damage prior to installation and assembly. Suspectcomponents should be rejected or returned to the factory for verification.
Connector assembly and installation should only be carried out by properly trained personnel. Proper tools must be
used during installation and / or assembly in order to obtain safe and reliable performance.
3. USE
Connectors with exposed contacts should never be live (or on the current supply side of a circuit). Under generalconditions voltages above 30 VAC and 42 VDC are considered hazardous and proper measures should be taken toeliminate all risk of transmission of such voltages to any exposed metal part of the connector.
4. TEST AND OPERATING VOLTAGESThe maximum admissible operating voltage depends upon the national or international standards in force for theapplication in question. Air and creepage distances impact the operating voltage; reference values are indicated in the
catalog however these may be influenced by PC board design and / or wiring harnesses.
The test voltage indicated in the catalog is 75% of the mean breakdown voltage; the test is applied at 500 V/s and thetest duration is 1 minute.
5. CE MARKING
CE marking
means that the appliance or equipment bearing it complies with the protection requirements of one orseveral European safety directives.
CE marking
applies to complete products or equipment, but not to electromechanical components, such as
connectors.
