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.
