Abstract
There is suppressed deterioration of transmission quality resulting from FWM light generated in the optical fiber of an optical transmission apparatus that performs wavelength division multiplex transmission. To suppress deterioration of the transmission quality due to the FWM light, the sender apparatus adjusts the intensity of wavelength-division-multiplexed light output to the optical fiber, according to a level of FWM crosstalk observed by receiver apparatus.
