Original Abstract Submitted
The light multiplexing/demultiplexing device comprises: a first demultiplexer that demultiplexes an inputted first wavelength-multiplexed signal light into a first signal light of a first wavelength band and a second signal light of a second wavelength band and outputs the first and the second signal light; a first amplifier that amplifies the second signal light from the first demultiplexer; a light processor that, based on the inputted second signal light and an inputted third signal light of the second wavelength band, outputs a fourth signal light; and a first multiplexer that multiplexes the fourth signal light with the first signal light from the first demultiplexer, further, the gain of the first amplifier is set such that the difference between power of the first signal light outputted from the first multiplexer and power of the fourth signal light outputted from the first multiplexer is equal to or less than a predetermined value.
