ABSTRACT:
An optical transmission system allowing precise error rate evaluations is disclosed. A transmitting element performs error-correction coding and transmits an error-correction coded transmission signal. A receiving element decodes the reception signal to produce decoding failure information when a decoding failure occurs, and calculates a number of errors after the error correction decoding based on the decoding failure information. The number of errors is determined based on an error-correcting capability of the error correcting code when the calculated parity information does not perfectly match the extracted parity information.
