OPTICAL TRANSMISSION APPARATUS, OPTICAL TRASMISSION SYSTEM, AND CONTROL METHOD OF OPTICAL TRANSMISSION SYSTEM

摘要

An optical transmission apparatus includes: an optical amplifier configured to amplify an optical signal; an optical power adjustment unit configured to adjust power of the optical signal output from the optical amplifier; and a controller configured to control an adjustment amount of the optical power in the optical power adjustment unit, in accordance with optical power control information obtained based on output optical power information per wavelength indicating output optical power that the optical amplifier is capable of outputting depending on a number of wavelengths included in the optical signal, and requisite signal quality information in a reception node which is to receive the optical signal output from the optical amplifier.
