9. An optical transmission method comprising:
outputting 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;
treating the user data as first data when the user data are output to the first channel, converting the first data into a first optical signal by first error correction coding processing and a first modulation method, and transmitting the first optical signal; and
treating the user data as second data when the user data are output to the second channel, converting 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 transmitting the second optical signal.
