Embodiments provide a data encoding method, a data decoding method, and a related device. The method includes a transmitting end device that determines N data symbols at a same symbol location of N links of service data, where N is an integer greater than 1, and quantities of bits in all data symbols are the same. The transmitting end device performs forward error correction (FEC) encoding on the N data symbols to obtain a codeword, where the codeword includes the N data symbols and M overhead symbols, M is an integer greater than or equal to 1 and less than or equal to N, and a quantity of bits in each data symbol is the same as a quantity of bits in each overhead symbol. The transmitting end device sends the N data symbols through N service channels, and sends the M overhead symbols through M overhead channels.
