Method, system, and access device for implementing error correction
A method, a system and an access device for implementing error correction are disclosed. The method includes upon receiving a data stream, identifying, by an access device, the data stream on which a forward error correction (FEC) needs to be performed and performing FEC coding on the data stream, and then sending out an FEC data stream generated by FEC coding together with a raw data stream, or sending out directly a data stream on which the FEC does not need to be performed. The system includes a data source for sending out a data stream and an access device for receiving the data stream from the data source, identifying the data stream on which a FEC needs to be performed, performing FEC coding on the data stream, and then sending out an FEC data stream generated by FEC coding together with a raw data stream, or sending out directly a data stream on which the FEC does not need to be performed. The bandwidth can be saved when the FEC is performed in data stream transmission, and it can be adapted to conditions of different access lines according to the invention.
