Abstract
An optical receiver may receive a data stream, and may decode the data stream using a first iterative forward error correction (FEC) decoder. The optical receiver may determine whether to further decode the data stream using the first iterative FEC decoder or a second iterative FEC decoder that is different from the first iterative FEC decoder. The optical receiver may selectively perform a first action or a section action based on determining whether to further decode the data stream. The first action may include providing the data stream to the first iterative FEC decoder or the second iterative FEC decoder for further decoding when the data stream is to be further decoded. The second action may include preventing the data stream from being provided to the first iterative FEC decoder or the second iterative FEC decoder when the data stream is not to be further decoded.
