Abstract: This application discloses a data processing method and apparatus. The method includes: distributing, by a first distribution circuit, a first bit stream to FEC encoders 1 to N in a round robin fashion, where digital signals 1 to N that are output after being encoded by the FEC encoders 1 to N are in a one-to-one correspondence with a least significant bit to a most significant bit of an input signal of a PAM circuit, a coding gain GX of an FEC encoder X is greater than a coding gain GY of an FEC encoder Y, 1≤X
