Abstract
A communication method includes: sending a first sequence including P subsequences A to a first device, where the first sequence is used by the first device to count a first bit error rate (BER), and the subsequence A is constituted by one or more forward error correction (FEC) code blocks; and sending a second sequence including Q subsequences B to the first device, where the second sequence is used by the first device to count a second BER, the subsequence B is constituted by one or more FEC code blocks, a length of the second sequence is greater than or equal to a length of the first sequence, and P and Q are positive integers.
