摘要：
A communication system includes a transmitter that combines and transmits a first signal light and a dummy light having a wavelength different from the first signal light; a first amplifier that amplifies a light transmitted by the transmitter to a constant power; a communication device that separates the dummy light from the light amplified by the first amplifier, has a variable transmittance and allows the separated dummy light to pass through, and combines and transmits the passed dummy light and a second signal light having a wavelength different from the dummy light; a second amplifier that amplifies a light transmitted by the communication device to a constant power; a receiver that receives the second signal light included in the light amplified by the second amplifier; and a controller that controls the transmittance.
