Abstract
An optical communication device includes a splitter, a first amplifier, a second amplifier, and a combiner. The splitter demultiplexes input signal light into first signal light and second signal light. The first signal light is amplified by the second amplifier after being amplified by the first amplifier. The second signal light is amplified by the first amplifier after being amplified by the second amplifier. The combiner multiplexes the amplified first signal light and the amplified second signal light.
