abstract

In this paper, we have proposed and demonstrated a novel architecture for orthogonal frequency division multiplexing wavelength-division-multiplexing passive optical network (OFDM-PON) with centralized lightwave and differential phase shift keying (DPSK) broadcast overlaid. In the architecture, 10-Gb/s 16QAM-OFDM point to point (P2P) signals and 2.5-Gb/s DPSK broadcast signals are used for downstream transmission. We employ a wavelength re-modulation for 2.5-Gb/s on-off keying (OOK) upstream signals to simplify the optical network unit as well as reduce the cost. Single-sideband (SSB) modulation format is utilized to eliminate the fading effect for downstream signals. The results show its prospect in future optical access network.
