Abstract: A data transmission method is performed by a first node, and the first node includes X encoding units that perform encoding in a first FEC mode. The method includes: first dividing, by the first node, to-be-encoded data into X groups of initial data, and encoding the X groups of initial data one by one by using the X encoding units, to obtain X groups of encoded data; and then distributing, by the first node, the X groups of encoded data to L links, to send the X groups of encoded data to a second node. Both X×N and X×K are integer multiples of L, N represents a length of a codeword of the first FEC mode, K represents a length of valid information bits in the codeword, and amounts of encoded data distributed to different links are the same.
