1. An optical switching device of the type comprising m light sources (211, 221, 231, 241), n photosensitive receivers (207 ; 407), m sets of n optical fibres (212, 222, 232, 242) each coupled at one end to a light source, each optical fiber (213, 223, 233, 243) emitting a light beam, shutters (215, 225, 235, 245) each placed on the path of a light beam and opening under the control of switching signals (V1, V2, V3, V4) to allow said beam to pass, characterized by the fact that each photosensitive receiver (207 ; 407) is coupled to one optical fiber (213, 223, 233, 243) of each of the m sets of optical fibers (212, 222, 232, 242). |
