Optical amplification apparatus, method for controlling same, optical receiver station, and optical transmission system

摘要

An optical amplification apparatus includes an optical amplification medium configured to receive a first light signal from an end of the optical amplification medium and a second light signal from the other end of the optical amplification medium in opposite directions, the first and second light signals being branched from a light signal, an excitation light source configured to supply excitation light to the optical amplification medium through a multiplexer, a monitor configured to monitor the first and second light signals input to the optical amplification medium, respectively and to output monitoring signals respectively, and a controller configured to control the excitation light source in accordance with the monitoring signals.
