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 to operate with single fibre, multi fibre, and mixed fibre optical/electrical cable constructions and cater to single and multi-mode fibres from 9/125 to 1500 urn diameter.

The choice of fibre optic contacts depends upon the following criteria:

- Cable construction (single fibre, multi fibre, mixed 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 to mixed optical/electrical connectors.
