Abstract
This system includes optical fibers (21,26,49,51) which connect subscriber sets (p,n) to an optical interconnection center (59). An optical frequency F.sub.p and a modulation frequency f.sub.p are ascribed to each subscriber p, these frequencies being specific to the subscriber. The set of each subscriber p includes a laser (19) which delivers a wave (22) of frequency F.sub.p and means (9, 12 to 18) to modulate the amplitude of this wave at the frequency f.sub.n ascribed to the subscriber n with whom he wishes to communicate.
