摘要：A passive, coexisting 10 Gb/s passive optical network (XGPON) and Gb/s passiveoptical network (GPON) is created by using a pair of counter-propagating laser pump
sources at a network-based optical line terminal, in combination with a feeder fiber, tocreate distributed Raman amplification for the upstream signals associated with bothGPON and XGPON systems. A passive remote node is located at the opposite end of thefeeder fiber, in the vicinity of a group of end-user locations, and includes a cyclic WDMand a pair of power splitters for the GPON and XGPON signals such that the GPONsignals are thereafter directed through a first power splitter into optical network units(ONUs) specifically configured for GPON wavelengths and XGPON signals are directedthrough a second power splitter into ONUs configured for the XGPON wavelengths. Thearrangement of the remote node allows for the reach and split ratios of the GPON andXGPON systems to be individually designed for optimum performance.
