ABSTRACT:
A wavelength division multiplexing system includes a first optical output level detector for detecting an optical output level of a first signal light transmitted on a transmission line, a signal light transmitter for transmitting an additional signal light to be multiplexed with the first signal light, and an optical coupler for multiplexing the additional signal light with the first signal light. The optical output level of the additional signal light is controlled on the basis of the optical output level of the first signal light transmitted on the transmission line.
