Abstract: A coding method and apparatus for data communication are provided, and may be applied to a plurality of scenarios such as a metro network, a backbone network, and a data center interconnection. As an example method, a first codeword is formed, where the first codeword includes n image bits and n to-be-transmitted bits. The n image bits are selected from to-be-transmitted bits in m source codewords. The m source codewords are formed before the first codeword. Both n and m are positive integers, and n>m; The n to-be-transmitted bits in the first codeword are sent. The bit in the first codeword can be protected by a plurality of codewords generated at different moments. In addition, the bit in the codeword can be protected by different quantities of codewords.

Abstract: This application discloses a transmission method for optical communication, which may be applied to various scenarios such as a metropolitan area network, a backbone network, and data center interconnect of over 400 Gbps (including 600 Gbps, 800 Gbps, and the like). The method includes: generating a super-frame including a plurality of sub-frames; and transmitting the super-frame, where each sub-frame includes training symbols and pilot symbols, and each of the training symbols and the pilot symbols is one of −A−Aj, −A+Aj, A−Aj, and A+Aj, A being a real number. In addition, in the training symbols and the pilot symbols included in each sub-frame, quantities of −A−Aj, −A+Aj, A−Aj, and A+Aj in two mutually perpendicular polarization directions meet specific requirements, so that direct current balance can be achieved, which helps a receiver end restore a signal.
