Abstract:
1. A hybrid passive optical network (“PON”), comprising: a time-division multiplexing (“TDM”) optical line terminal (“OLT”) for delivering communication services to a first group of customer premises (“CPs”) via TDM signals; a wavelength-division multiplexing (“WDM”) OLT for delivering the communication services to a second group of CPs via WDM signals; a remote node power splitter coupled to receive the TDM signals and the WDM signals and to broadcast both the TDM signals and the WDM signals on all ports of the remote node power splitter facing towards the first and second groups of CPs; and optical filters each disposed between the remote node power splitter and a corresponding one of the second group of CPs, each of the optical filters 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 the WDM signals but does not receive the WDM signals allocated to other CPs of the second group of CPs.
