Abstract
An optical transmission device is configured to receive and process an optical signal received via an optical transmission line, the optical transmission device including: an output unit configured to output information concerning deviation of an amplitude characteristic of the received optical signal; a tunable optical filter (TOF) configured to filter the received optical signal; a controller configured to control a setting of the TOF based on the information concerning the deviation of the amplitude characteristic.
