Classification: CPC H | IPC H

Claim 4:
5. An optical transmission method carried out by a server that performs optical transmission using an optical transmission line,
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 error correction using an error correction code ECC) stored in a storage device of the server is equal to or less than a reference error rate, the optical transmission method comprising:
by the server functioning as a transfer source:
reading data and the ECC from the storage device of the server;
converting the read data and the ECC into an optical signal; and
transmitting the converted optical signal from a transmitter of the server, and

by the server functioning as a transfer destination:
receiving an optical signal using a receiver of the server;
converting the received optical signal into data and an ECC; and
storing the data, which has been subjected to error correction using the ECC, and the ECC in the storage device of the server.
