In telecommunication, information theory, as well as coding theory, Forward Error Correction (FEC) or channel coding is a technique used for controlling errors in data transmission over unreliable or noisy communication channels. The essential idea is the sender encodes their message in a redundant way by using an Error-Correcting Code (ECC). FEC is very powerful tool for implementation of hybrid Wdm/Tdm passive optical network. Only an estimation was given in ITU-T recommendation G.984.3, stating that FEC results within a link budget increase of approximately 3 - 4 dB additional power.
