Abstract: This application discloses an Ethernet coding method and apparatus, to adapt to a scenario in which a higher transmission bit error rate is caused by a high bandwidth. The method includes: a transmit end encodes first to-be-encoded information by using a first forward error correction (FEC) codeword, to obtain first encoded data, where the first forward error correction FEC codeword is a Reed-Solomon forward error correction (RS-FEC) codeword; and the transmit end encodes the first encoded data by using a second FEC codeword, to obtain second encoded data, where a code length N and an information bit length K of the second FEC codeword satisfy the following formula: M ⁢ 1 * N K ≤ M ⁢ 2 , where M1 is a throughput of the first encoded data, and M2 is a throughput of the second encoded data.
