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.

Abstract: The present disclosure relates to a communication apparatus and a data transmission method. In an example, the communication apparatus includes a universal serial bus (USB) protocol layer, a USB adapter layer, a transport layer, and a physical layer. The USB protocol layer is configured to send first data to the USB adapter layer. The USB adapter layer is configured to perform physical link adaptation on the first data to obtain second data and send the second data to the transport layer. The first data is adapted to a first physical link, the second data is adapted to a second physical link, and a bandwidth of the first physical link is lower than a bandwidth of the second physical link. The transport layer and the physical layer are configured to process the second data and send processed second data to a receive end through the second physical link.
