OPTICAL CROSS CONNECT DEVICE, LIGHT INSERTION BRANCH DEVICE AND LIGHT SOURCE DEVICE

摘要

PROBLEM TO BE SOLVED: To use prescribed optical wavelengths from a few light sources for mush modulation processing by supplying N pieces of light from M sets of wavelength filter parts as input light. SOLUTION: A light source device 50 supplies input light that has desired wavelength which is modulated in M sets of optical regenerative repeaters 20-1 to 20-M. A synthetic branching part 52 of the device 50 generates synthetic light which has N kinds of optical wavelength components by synthesizing light from N pieces of light sources and also outputs the synthetic light which is branched into M×N pieces as synthetic distribution light. N pieces of synthetic distribution light which are branched among M×N pieces of synthetic distribution light by the part 52 are performed distribution input to each wavelength filter part 53-1 to 53-M, and only optional wavelengths among N kinds of light wavelengths output N pieces of light that pass. A wavelength set controlling part 54 sets light wavelengths that pass through the parts 53-1 to 53-M so that they may be set mutually different.
