Abstract
PURPOSE:To enable to prevent the collision at station, by making the communications of a plurality at the same time by assigning different wave lengths to each station and storing the signal transmitted with respective length to the reception memory. CONSTITUTION:The communication network is constituted with 4 stations 100, 200, 300, 400 and star type light network 500. Each station has the transmission circuit T and the reception circuit R. The light circuit network 500 has the passive type star coupler 510 and optical fiber pairs 521-524 connecting each station. For example, in the station 200, the circuit T has LED524 outputting the light in wave length lambda2, and the circuit R brancher 211 branching the transmitted light via the optical fiber pair 522, BPF221-223, photo detectors 231-233, and reception memories 241-243. Thus, different wave length from each station is assigned to make a plurality of communications, and the signal transmitted with respective wave length is provided with the reception memory, allowing to prevent the collision at the stations.
