ABSTRACT:
There is disclosed an optical source generator for wavelength division multiplexing optical communication systems. The optical source generator includes first and second pumping light generators; a first wavelength router for wavelength-division-demultiplexing first pumping lights inputted into a multiplexing port of its first port section to output the demultiplexed pumping lights to the demultiplexing ports of its second port section, and for wavelength-division-demultiplexing second pumping lights inputted into the multiplexing port of its second port section to output the demultiplexed pumping lights to the demultiplexing ports of its first port section; a plurality of first and second optical fiber amplifiers; a second wavelength router for wavelength-division-multiplexing optical signals inputted from the first optical fiber amplifiers into the demultiplexing ports of its first port section, and outputting the multiplexed optical signals to the multiplexing port of its second port section, and for wavelength-division-multiplexing optical signals inputted from the second optical fiber amplifiers into the demultiplexing ports of its second port section, and outputting the multiplexed optical signals to the multiplexing port of its first port section; and first and second optical band pass filters, wherein two groups of optical sources are generated bilaterally.
