In an optical concentrator, a plurality of ports are provided for inputting and outputting first and second optical signals having different wavelength regions. An optical coupler is connected to each of the plurality of ports without being through remaining ones of the plurality of ports. The optical coupler transmits the second optical signal input from one of the plurality of ports to at least one of the remaining ports. A transmitter is provided to connect the plurality of ports in a loop form. The first optical signal input from each port is transmitted from the transmitter. Demultiplexers are arranged at each port for demultiplexing the first and second optical signals input from each port so as to guide the first optical signal to the transmitter and the second optical signal to the optical coupler.
L'invention est un concentrateur optique comportant une pluralité de ports servant à recevoir et à transmettre un premier et un second signal lumineux de longueurs d'onde différentes. Un coupleur optique est connecté à chacun des ports en cause. Ce coupleur transmet à au moins un des autres ports le second signal lumineux provenant de l'un des ports. La pluralité de ports est connectée en boucle par un émetteur. Celui-ci transmet le premier signal lumineux provenant de chacun des ports. Des démultiplexeurs sont montés à chacun des ports pour démultiplexer le premier et le second signal lumineux provenant de chaque port afin d'acheminer le premier signal à l'émetteur et le second au coupleur optique.
