Claim 0:
1. A server that performs optical transmission using an optical transmission line, the server comprising:
a transmitter configured to transmit an optical signal to a second server;
a receiver configured to receive the optical signal from the second server;
a storage device configured to store data and an error correction code (ECC) added to the data; and
a control unit, including one or more processors, configured to control conversion of the data and the ECC into the optical signal, conversion of the optical signal into the data and the ECC, and error correction of the data using the ECC,
wherein a transmission distance of the optical transmission line is a transmission distance over which an error rate, before error correction, does not exceed an allowable value of the error rate, such that an error rate after correction based on the error correction using the stored ECC is equal to or less than a reference error rate.
