Fibre Optic

Connectors

Dear Customers,

As far as data transmission is concerned, the superior characteristics of fibre optics compared to elec-

trical 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 handling

and 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 neighbouring

lines. 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 trans-

mission, 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 multi-

mode transmission. This product range is available with metal or plastic outer shells, as well as in a wa-

tertight 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

for plug 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 established an

important research and development facility to provide quick and effective solutions to your design re-

quirements.

LEMO ISO 9001 certified has been improving its “quality culture” with the aim of reaching TQM. Offering

zero defect products with due regard to the environment and meeting delivery requirements, are LEMO’s

two main concerns.
