摘要： The invention provides a method and apparatus for reconfiguring wavelength of the ONU. To be specific, the OLT sends a Deactivate_ONU-ID message to the ONU, the Deactivate_ONU-ID message including a reconfiguration flag, a new receive wavelength assigned for the ONU and a new transmit wavelength assigned for the ONU. After receiving the Deactivate_ONU-ID message from the OLT, the ONU discards the TC layer parameters related to the current wavelength channel, and determines whether the reconfiguration flag included in the Deactivate_ONU-ID message indicates the receive wavelength and the transmit wavelength of the ONU are required to be reconfigured. If so, then the ONU replaces its original receive wavelength and original transmit wavelength with its new receive wavelength and the new transmit wavelength included in the Deactivate_ONU-ID message, and enters initial state; and if not, then the ONU enters initial state directly.

摘要： The present invention discloses a time/wavelength-division multiplexed passive optical network (TWPON), which has an optical splitter (21) and a waveguide grating router (WGR) (22) disposed at a remote node (RN) (20). The optical splitter (21) and the WGR (22) can be connected in a cascade or in a parallel such that the present invention can use less number of wavelengths to increase transmission capacity or increase the number of users. A channel fault monitoring (CFM) module provided at an optical line terminal (OLT) is utilized to locate fiber breaks among distribution fibers. The TWPON of the present invention can provide TDM-PON, WDM-PON, and Hybrid PON co-existing platform with less wavelengths channel fault monitoring mechanism.

摘要： A hybrid passive optical network (“PON”) includes a time-division multiplexing (“TDM”) optical line terminal (“OLT”) and a wavelength-division multiplexing (“WDM”) OLT. The TDM OLT communicates with a first group of customer premises (“CPs”) via TDM signals while the WDM OLT communicates with a second group of CPs via WDM signals. A remote node power splitter is coupled to receive the TDM and WDM signals and broadcast both the TDM signals and the WDM signals on all of its ports facing towards the CPs. Optical filters are disposed between the remote node power splitter and the second group of CPs. Each optical filter is configured to pass a sub-group of the WDM signals while blocking other WDM signals such that each of the second group of CPs receives its own allocation of WDM signals but does not receive WDM signals allocated to other CPs of the second group of CPs.
