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.
