METHOD AND DEVICE FOR ERROR CORRECTION

摘要

Provided is an error correction method for an optical communication system that transmits a transmission frame formed of information data added with an overhead and an error correction code, the error correction method including adjusting a size of an FEC redundant area of an FEC frame for storing client signals of different signal types in accordance with the client signals so that transmission rates of the FEC frame for the respective client signals have an approximately N-multiple relationship (N is a positive natural number). With this, it is possible to obtain an error correction method and device capable of providing a high-quality and high-speed optical communication system without performance degradation caused by jitter or the like and with the common use of circuits having a reduced circuit scale.
