发明名称 Optical amplifying method
摘要 A method of amplifying a signal light includes initially multiplexing a signal light and a pumping light, initially amplifying the signal light initially demultiplexing so as to separately output the amplified signal light and the pumping light, and modifying a waveform of the amplified signal light so as to compensate for waveform distortion of the signal light along a transmission path of the signal light and providing an output of a waveform modified signal light. Thereafter, the waveform modified signal lights is secondarily multiplexed, secondarily amplified, and secondarily demultiplexed with a waveform of amplified signal light being compensated for waveform distortion of the signal light along a transmission path of the signal light an output of a waveform modified signal light. The waveform modified signal light is thirdly multiplexed and thirdly amplified so as to provide an output of amplified waveform modified signal light.
