Optical multiplex communication system

摘要: An optical multiplex communication system in which n kinds of digital signals whose logical levels do not simultaneously become true, such as, pulse motor controlling pulses, are multiplexed through a single fiber line. The transmitting end generates carrier clock different frequencies by generating means, produces the respective products and then sum product outputs circuits converts output to light signal transmitter, thereby delivering onto On other hand, receiving receives reconverts an electric receiver, applies band-pass filters each having pass band corresponding frequency one extract according frequency, detects filter detection circuit means restore it transmitted signal.
