ABSTRACT:
An optical transmission equipment includes an optical amplifier that is coupled to an optical transmission path and amplifies a first optical signal which is received from the optical transmission path, a first controller that controls the optical amplifier depending on a first optical power of output light from the optical amplifier and a second optical power of reflecting light to the optical amplifier, an optical coupler that branches a second optical signal from the optical amplifier into a first output and a second output, an optical demultiplexer that demultiplexes the first output of the optical coupler, an optical switch or attenuator that receives the second output of the optical coupler, and a second controller that controls the optical switch or attenuator depending on a third optical power of output light from the optical switch or attenuator and a fourth optical power of reflecting light to the optical switch or attenuator.
