Abstract: A signal processing method, an optical receiver and optical network system is provided. The method includes: receiving a first optical signal sent by an optical network unit, generating a second optical signal and modulating a phase of the second optical signal, obtaining at least one path of electrical signals after the first optical signal and the second optical signal separately undergo polarization splitting, frequency mixing, and optical-electrical conversion, outputting a third electrical signal after performing operation processing on the at least one path of electrical signals, and restoring a data signal according to the third electrical signal and performing sending. The embodiments example benefits are greatly reducing complexity of system implementation and maximally reducing a system upgrade cost and an optical power loss.

Abstract: Embodiments of the present invention provide a downstream data frame transmitting method. The method includes: generating, by an OLT, a downstream data frame, where the downstream data frame includes a frame header and a payload, the frame header includes a physical synchronization sequence (Psync) field, and the Psync field is used to identify the downstream data frame, where when a value of the Psync field is a first value, the Psync field is further used to indicate that payload data is protected by forward error correction (FEC); or when a value of the Psync field is a second value, the Psync field is further used to indicate that payload data is not protected by FEC; and sending, by the OLT, the downstream data frame. The embodiments of the present invention can reduce a bit error rate of a FEC indication status and improve reliability of the FEC indication status.

Abstract: The present invention provides a method, a system, and an apparatus for data communication in an optical network system. A new encoding scheme is implemented in the following manner: performing 32-bit to 34-bit encoding on a data stream on which 8-bit/10-bit decoding has been performed, performing forward error correction encoding on the data stream on which the 32-bit to 34-bit encoding has been performed, and sending the encoded data stream; or performing forward error correction decoding on a received data stream, and performing 32-bit to 34-bit decoding on the data stream on which the forward error correction decoding has been performed. In this way, a bandwidth resource of a line is saved; line monitoring can be implemented without interrupting a service, which is easy to implement and greatly improves various types of performance of the system.
