Abstract: Embodiments of this application disclose a board, an optical module, a MAC chip, a DSP, and an information processing method. The board in the embodiments of this application includes a media access control (MAC) chip, a digital signal processor (DSP), and an equalizer. The MAC chip is configured to send first information to the DSP at an optical network unit (ONU) online stage, where the first information includes a first ONU identifier. The DSP is configured to receive the first information, and determine a first reference equalization parameter, where the first reference equalization parameter is related to the first ONU identifier. The DSP is further configured to set an equalization parameter of the equalizer to the first reference equalization parameter.

Abstract: Embodiments of this application provide an upstream resource grant method, a device, a passive optical network, and a computer-readable storage medium. The upstream resource grant method includes: An optical line terminal obtains an upstream grant message on which transformation processing has been performed, where a transformation parameter used for the transformation processing includes a physical identity of an optical network unit (ONU); and the optical line terminal sends the upstream grant message on which the transformation processing has been performed, where the upstream grant message carries an upstream resource grant indication of the optical network unit, and the upstream resource grant indication is used to indicate an upstream resource granted to the optical network unit. The technical solutions provided in the embodiments of this application help reduce an occurrence probability of a rogue ONU phenomenon, and further improve service running stability of a PON system.

Abstract: The present disclosure relates to passive optical network (PON) systems, optical line terminals (OTLs), and optical network units (ONUs). One example PON system includes an OLT and at least two ONUs. The OLT and the ONUs exchange data on one downstream channel and two upstream channels. The OLT sends downstream data to each ONU on the downstream channel, where the downstream data includes an upstream bandwidth grant used to control each ONU to send upstream data. Each ONU receives the downstream data on the downstream channel, and sends the upstream data on a first upstream channel or a second upstream channel based on the upstream bandwidth grant included in the downstream data. The OLT receives, on the first upstream channel and the second upstream channel, the upstream data sent by each ONU, where a registration function is disabled on the first upstream channel, and enabled on the second upstream channel.

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.
