Optical transmission device and optical transmission system

摘要

An optical transmission device includes an error correction scheme determining unit, an error correction encoder, a modulation format determining unit and an optical transmitter. The error correction scheme determining unit determines an error correction scheme based on a latency between the optical transmission device and a correspondent device. The error correction encoder generates encoded data by performing an error correction encoding on transmission data using the error correction scheme determined by the error correction scheme determining unit. The modulation format determining unit determines a modulation format based on the error correction scheme determined by the error correction scheme determining unit and transmission characteristics between the optical transmission device and the correspondent device. The optical transmitter generates a modulated optical signal from the encoded data with the modulation format determined by the modulation format determining unit.
