A system, method, and node for extending the reach of a fiber-based access network. A Remote Protocol Termination, RPT (23) is implemented remotely from a central office Optical Line Termination, OLT (25). The RPT receives a data signal transmitted by a user's Optical Network Unit/Termination, ONLVT (21) over a Passive Optical Network, PON (51) utilizing a PON protocol or Wavelength Division Multiplexing, WDM, based protocol, and converts the signal to a long-reach transport protocol. The RPT then transmits the data signal to the central office OLT utilizing the long-reach transport protocol. The RPT (23) also performs this protocol conversion in the opposite direction for signals transmitted from the central office OLT (25) to the ONU/T (21). |
