Abstract
An optical interconnection circuit includes a fixed number (N) of interconnected circuits (C1 to C16). Each circuit has an optical emitter (E1 to E16) and at least one optical receiver (R1, R16). The emitter outputs an optical wavelength which is specific to the circuit on which it is located. An optical coupler (CE) connects the emitter in each circuit to all receivers in the other circuits and each circuit (C1 to C16) has an address for identifying that particular circuit. The value of this address is applied to the emitter to adjust the optical wave length at which the emitter operates.

Optical interconnection system, comprising:
- a fixed number of circuits to be interconnected, each circuit including an optical emitter and at least one optical receiver, the emitter located on a board emitting at an optical wave length specific to this said each circuit;
- an optical coupler connecting the emitter in each circuit to all receivers in other circuits;
- wherein each circuit has an identifying address, a value of said address being applied to the board emitter to adjust the optical wave length at which the emitter emits and wherein the address is supplied to a circuit by an external device as a function of the rank of said circuit from among said fixed number of circuits to be interconnected.
