In this paper we present a reach extension technique that can be used in the future Next Generation-Passive Optical network (NG-PON). We address to the high bandwidth demand, power budget enhancement, and the number of subscribers. Here, we consider Differential Phase Shift Keying (DPSK). We demonstrate our experimental results for 12λ×10 Gbit/s/λ Wavelength Division Multiplexing (WDM) technology
