Abstract:
A remote node for a wavelength-division-multiplexed passive optical network (WDM PON). The remote node comprises means for receiving uplink optical signals from one or more optical network units of the WDM PON; a broadband reflector for reflecting a self-seeding portion of the respective uplink optical signals to the respective uplink light sources; and wherein the reflector comprises a gain medium and is configured for receiving a pump optical signal from a central office of the WDM PON for amplifying the self seeding portion of the respective uplink optical signal.
