Abstract

This paper proposes a hybrid passive optical network (PON) system based on a dense wavelength division multiplexing-PON (DWDM-PON) and reach extender (RE) for increasing the optical link budget and link capacity in an existing gigabit PON (GPON) system. A DWDM-PON is applied to the feeder fiber and is interfaced with the RE. The RE provides a wavelength conversion between the DWDM-PON and GPON through frame regeneration, and controls upstream burst signals. The hybrid PON system enables a legacy GPON system to operate over a minimum 40 km distance with a 128-way split per WDM wavelength.
