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.

Abstract: A data processing method includes the following operations: separately performing convolutional interleaving on n lane data streams to obtain n first data streams, where n>1, and first FEC encoding is performed on all the n lane data streams. Every a codewords obtained through the first FEC encoding are distributed in b lane data streams, where a≤b≤n, and a≥1. z consecutive symbols in each of the first data streams are from z different codewords, and z>1. Then, every K first data streams of the n first data streams are multiplexed to obtain one second data stream, so as to obtain a total of m second data streams. The n first data streams include G first data stream subsets, symbols in different first data stream subsets are from different codewords, m=n/K, K>1, and G>1. y consecutive symbols in each second data stream are from y different codewords, where y>z.
