In computing, telecommunication, information theory, and 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.
Forward error correction (FEC) is a method for obtaining error control in data transmission in which the source (transmitter) sends redundant data and the destination (receiver) recognizes only the portion of the data that contains no apparent errors.
Viasat 66200 SDFEC (soft decision forward error correction) is a family of turbo product codes (TPC) designed for use in high speed optical communications (100, 200, 400, 800G).
Error control coding is sometimes called forward error correction (FEC) because only a forward channel is used. However, in a packet network there is usually a backward channel, so that acknowledgments can be fed back from receiver to transmitter, resulting in the familiar ACK/NAK signal.
RFC 6363 FEC Framework October 2011 Forward Error Correction (FEC) is a well-known technique for improving the reliability of packet transmission over networks that do not provide guaranteed packet delivery, especially in multicast and broadcast applications.

Sep 4, 2018 · This article introduces Forward Error Correction (FEC), a function capable of correcting errors in the received data, how it came about and some of the benefits and trade-offs in its operation. The diagram shows the voltage transition from logic “0” to logic “1”, then back to logic “0”.
