LEMO offers 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 a watertight 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.
