    Abstract: This application provides a data processing method and a second communication apparatus, to resolve a problem of relatively long data synchronization time in a conventional technology, and may be applied to augmented reality AR, virtual reality VR, artificial intelligence AI, cloud applications, or other fields. The data processing method includes: A second optical module receives first data from a first optical module, and determines out-of-synchronization lock based on the first data. The second optical module sends, to a second host, first indication information indicating that the second optical module is in out-of-synchronization lock state. The second optical module receives second data from the first optical module, determines synchronization lock based on the second data, and sends, to the second host, second indication information indicating that the second optical module is in synchronization lock state.

    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: M1*N/K≤M2, where M1 is a throughput of the first encoded data, and M2 is a throughput of the second encoded data.

    Abstract: An encoding method, a decoding method, and an optical module are described relating to data transmission technologies. The method, carried out by an optical module includes obtaining an optical transmission mode used for signal transmission. The method further includes receiving a signal on which outer-code encoding has been performed. The optical module determines, based on the optical transmission mode, an inner-code encoding scheme to be used by the optical module to perform inner-code encoding on the signal on which outer-code encoding has been performed. The method further includes performing, by using the inner-code encoding scheme, inner-code encoding on the signal on which outer-code encoding has been performed. The optical module outputs a signal on which inner-code encoding has been performed. As a result, error correction performance of the Ethernet may be improved.

    Abstract: A data transmission apparatus includes z physical coding sublayer (PCS) lanes and z convolutional interleaving modules, where one convolutional interleaving module corresponds to one PCS lane. The convolutional interleaving module includes x levels of cascaded convolutional interleavers, where x is an integer greater than 1, and z is a positive integer. The PCS lane is configured to receive a first data stream from a PCS, where one first data stream corresponds to one PCS lane. The convolutional interleaving module is configured to perform interleaving processing on a first data stream from a corresponding PCS lane, to obtain a second data stream, where an interleaving depth of the second data stream is related to a quantity of input bits of an inner-code encoder. The cascaded interleavers enables a quantity of levels of the cascaded interleavers to be flexibly selected.
