摘要： Techniques, apparatus and systems are described for an optical line terminal (OLT) operable in a passive optical network (PON) system to isolate and mitigate the behavior of a rogue optical network unit (ONU) that transmits optical power up the optical distribution network (ODN). In one aspect, a method of mitigating the behavior of rogue ONUs can include detecting the presence of a rogue ONU on the PON system, and transmitting, based on the detection, a message addressed exclusively to the ONUs that have not yet been discovered or identified by the OLT.

摘要： A method for managing upstream burst overhead parameters includes: an Optical Line Terminal (OLT) or an Optical Network Unit (ONU) detects transmission quality of a downlink between the OLT and the ONU; the OLT or the ONU determines the upstream burst overhead parameters suitable for the ONU according to the transmission quality; and the ONU starts to use the upstream burst overhead parameters suitable for the ONU after the switching time determined by the ONU itself or indicated by the OLT. The present invention also provides an ONU and an OLT for managing the upstream burst overhead parameters. The present invention can improve the bandwidth utilization rate and decrease the complexity of indicating the upstream burst overhead parameters in PON system, so that the ONU and the OLT are enabled to flexibly and simply select the upstream burst overhead parameters.

摘要： Disclosed in the present invention are an alarm processing method and device for a PON system in power-saving mode, for solving the technical problem that the PON system cannot process the alarm or exception message after the ONU enters power-saving state and the management server is misled to deem that the system is abnormal. In the present invention, when the OLT detects the alarm generated for a certain ONU, it acquires the current power-saving working state of the ONU, and if the ONU is currently in power-saving state (such as doze state, i.e. Tx mode), the OLT suppresses, discards or shields the relevant alarm by the ONU currently in power-saving state. By way of the present invention, the alarm processing pressure can be alleviated and the real state of the ONU can be reflected.

摘要： The disclosure provides a method and system for realizing power saving mechanism management between an Optical Network Unit (ONU) and an Optical Line Terminal (OLT). The method includes: passing power saving information between the ONU and the OLT through an extended Operation Administration and Maintenance (OAM) frame; closing/opening an optical module of the ONU based on the obtained power saving information. With the method of the disclosure, the optical module is closed in time when the optical module of the ONU is not needed, thus reducing power consumption of the ONU, and enabling interaction between the ONU and the OLT to meet the requirement for power saving and emission reduction.
