Optical transmission device and optical transmission system

摘要

An optical transmission device includes: an error correction scheme determining unit (19a) configured to determine an error correction scheme based on a latency between the optical transmission device and a correspondent device; an error correction encoder (11a) configured to generate encoded data by performing an error correction encoding on transmission data using the error correction scheme determined by the error correction scheme determining unit; a modulation format determining unit (20a) configured to determine 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; and an optical transmitter (13a) configured to generate a modulated optical system from the encoded data with the modulation format determined by the modulation format determining unit.
