A 10Gb/s and 40Gb/s forward-error-correction device for optical communications

A 10 Gb/s and 40 Gb/s forward-error correction (FEC) device for optical communications was discussed. It incorporated 16-way interleaved RS(255,239) FEC, an optical transport network digital wrapper framer and a BCH(4359,4320) in-band FEC. High-rate FEC codes are used in longhaul optical communicati...

Summary:A 10 Gb/s and 40 Gb/s forward-error correction (FEC) device for optical communications was discussed. It incorporated 16-way interleaved RS(255,239) FEC, an optical transport network digital wrapper framer and a BCH(4359,4320) in-band FEC. High-rate FEC codes are used in longhaul optical communication systems to provide significant coding gains with low overhead. Time-multiplexing one key equation solver block among 4 decoders in the device leads to substantial hardware savings as it is the most complicated block in Reed-Solomon (RS) decoding.
