<P>PROBLEM TO BE SOLVED: To flexibly install more optical transmitters/receivers in a single-core bidirectional wavelength multiplexed transmission system. <P>SOLUTION: The single-core bidirectional wavelength multiplexed transmission system has a wavelength multiplexed transmitter which transmits a wavelength multiplexed optical transmission signal in which optical transmission signals are wavelength multiplexed, performs wavelength division to wavelength multiplexed optical receiving signals into optical receiving signals and receives optical receiving signals with the adjacent wavelength to each wavelength of the optical transmission signals, an optical transmitter/receiver which receives the optical transmission signals with a part of wavelength and transmits the optical receiving signals with the adjacent wavelength to each wavelength of the optical transmission signals and an optical branching insertion unit which is connected to the wavelength multiplexed transmitter or other optical branching insertion device and the optical transmitter/receiver via a single-core optical fiber transmission path, branches the optical transmission signal with one wavelength of the wavelength multiplexed optical transmission signals to transmit it to the optical transmitter/receiver, receives the optical receiving signal with the adjacent wavelength to the wavelength of the optical transmission signal from the optical transmitter/receiver and inserts the optical receiving signal into the wavelength multiplexed optical receiving signals. <P>COPYRIGHT: (C)2007,JPO&INPIT |
