Communications method, system, and apparatus for optical network system

摘要

Provided are a data communication method, system and device for an optical network system. By means of performing 32-bit to 34-bit coding on a data stream subjected to 8-bit/10-bit decoding and performing forward error correction coding on the data stream subjected to 32-bit to 34-bit coding, and sending out the data stream subjected to coding, or performing forward error correction decoding on a received data stream and performing 32-bit to 34-bit decoding on the data flow subjected to decoding, a new coding manner is realized, saving the bandwidth resources of a line, meanwhile monitoring of the line in the case of traffic not being interrupted is realized, and the implementation is simple, greatly improving the overall performance of the system.
