TRANSMISSION DEVICE

摘要

A transmission device transmitting a polarization-multiplexed optical signal includes: a frame encoder configured to encode an electric signal in accordance with a predetermined frame format; an error correction encoder configured to provide encoded signal data as a result of the encoding by the frame encoder with a predetermined error correction code; and a transmission loss information acquiring part configured to acquire transmission loss information based on a loss that the encoded signal data provided with the error correction code incurs when the encoded signal data is transmitted, from a receiving device as a transmission destination. The error correction encoder adjusts a redundancy of the error correction code given to the encoded signal data, based on the transmission loss information acquired by the transmission loss information acquiring part.
