What is FEC (Forward Error Correction)?

by M***d on 11/22/2024

FEC (Forward Error Correction) is an error correction technique todetect and correct a limited number of errors in transmitted data without the need for retransmission. It works by adding redundant bits to a bitstream to help the decoder odetect and correct some transmission errors without the need for retransmission. This function needs to be turned on by the transmission device.
