Abstract: Example link training methods and apparatus are described. In one example, a first device is connected to a second device through a cable, the first device includes a first transmit end and a first receive end, the second device includes a second transmit end and a second receive end, and the cable includes at least one first link from the first transmit end to the second receive end and at least one second link from the second transmit end to the first receive end. The first device performs link training on the at least one first link. When link training is not performed on the at least one second link, or before link training on the at least one second link succeeds, the first device sends data to the second device through at least one first link on which link training succeeds.

Abstract: This application provides example forward error correction (FEC) code design methods and example related devices. One example method includes determining a quantity of transmission lanes for transmitting data. A plurality of FEC working areas can be determined based on the quantity of transmission lanes, where a quantity of the plurality of FEC working areas is the same as the quantity of transmission lanes, and the plurality of FEC working areas are for performing check and error correction on the data. The data on a transmission lane of the transmission lanes can be evenly allocated to each of the plurality of FEC working areas. The data received by each of the plurality of FEC working areas can be processed by using the plurality of FEC working areas.
