ABSTRACT:
The invention provides a multi-channel optical coupler forming a single component which can be attached to the front panel of an equipment. A single central U-shaped optical fibre acts as a mixer waveguide. The terminal faces of this central waveguide are coplanar and optically connected to the single fibres or to the bunches of fibres, which constitute the incoming and outgoing channels, by two sets of single intermediate mixer fibres. Each intermediate fibre is equipped with a standard mechanical connecting element of detachable design, all these connecting elements being arranged in the same plane.
