This catalog gives the complete description of LEMO
fibre optic connectors. Our manufacturing program
has been extended to 12 series with specific mating and
environmental characteristics.
Each series includes a wide variety of plugs, sockets
or housings for electro-optic devices available in a
large choice of combinations of fibre optic and electrical
contacts within the same housing.
Shells are adapted to all round cables to a maximum dia-
meter of 25 mm.
LEMO connectors feature ceramic or metal ferrules
for the fibre optic contacts to provide alignment for both
single-mode and multi-mode fibres.
They are manufactured to the highest precision in order
to ensure optimum optical performances even in the most
severe applications.
Numerous accessories as well as a complete range of
tools for fibre optic termination, are available.
The 00 Series
The characteristic feature of this connector series
is the small 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 for use
with large size multi-mode fibres ranging from 140 to
1500 micron external diameters.
The 0K Series
This series is watertight (IEC 60529/IP 66-IP 68) and is
ideal for use in harsh environments.
It uses the standard LEMO F2 fibre optic contact which
has undergone extensive mechanical, optical and envi-
ronmental testing.
Connectors are suitable for use with single fibre cables
fitted with single-mode or multi-mode fibres.
Propagation of Light and Fibre Type
The diagrams show the typical transmission characte-
ristic 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 very
small and consequently they offer higher bandwidths
when compared with multi-mode fibres. However, multi-
mode fibres are usually ideal for short distance applica-
tions because they require less input optical power and
can be driven by simple low cost LEDs.
Introduction
The 2B to 5B Series
These connectors series range from 2B to 5B, and have
been designed to work with LEMO F1 or F2 type fibre
optic contacts. They are suitable for use with multi fibre or
mixed fibre optical/electrical cables fitted with single-
mode or multi-mode fibres up to 1500 micron in diameter.
The connectors offer a variety of features:
– alignment key preventing all errors in alignment;
– polarized keying system, the various keying alterna-
– higher contact density; and
– possible use of crimp contacts to reduce cable assem-
The 2K to 5K Series
This product family includes the 2K to 5K series, and are
watertight (IEC 60529/IP 66-IP 68) available in the same
types as the 2B to 5B series. The connectors are ideal for
use in harsh environments.
The video HDTV 3K.93C Series
This new range of high performance fibre optic camera
connectors has been developed to meet the needs of the
new generation of digital TV cameras. Contact configura-
tion 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 equip-
ment such as those specified in UL 1419 «Professional
Video and Audio Equipment»
