Definition of "FEC" |
Forward Error Correction: A technique for detecting and correcting errors from imperfect transmission by adding a small number of extra bits. FEC allows optical transmission over longer distances by correcting errors that can happen as the signal-to-noise ratio decreases with distance. / Forward Error Correction, facilities engineering command, / Forward Error Correction is a technique for detecting and correcting errors from imperfect transmission by adding a small number of extra bits. It allows optical transmission over longer distances by correcting errors that can happen as the signal to noise ratio decreases with distance. / Forward Error Correction a method of error correction at the receiver end in a one-way data transmission. Along with the signal data, additional information about the signal is transmitted. The additional information can reconstruct corrupted data. / In 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. The central idea is the sender encodes their message in a redundant way by using an error-correcting code (ECC). The American mathematician Richard Hamming pioneered this field in the 1940s and invented the first error-correcting code in 1950: the Hamming (7,4) code. / Fiber to the node is one of several options for providing cable telecommunication services to multiple destinations. Fiber to the node helps to provide broadband connection and other data services through a common network box, which is often called a node. / See forward error correction. |
