Abstract
An optical transmission device includes: a route control unit that outputs user data including destination information to a first channel or a second channel, based on a latency associated with each destination included in the destination information; a first optical transmission unit that treats the user data as first data when the user data are output to the first channel, converts the first data into a first optical signal by first error correction coding processing and a first modulation method, and transmits the first optical signal; and a second optical transmission unit that treats the user data as second data when the user data are output to the second channel, converts the second data into a second optical signal by second error correction coding processing different from the first error correction coding processing, and a second modulation method different from the first modulation method, and transmits the second optical signal.
