Abstract

Abstract: OFDM (orthogonal frequency-division multiplexing)-PON (passive optical network) is considered a promising solution for the next generation PON-based access networks. Meanwhile, the released 40/100 Gbit/s Ethernet standard allows 100 Gbit/s fiber transmission to be realized in the near future. We propose a novel OFDM-PON architecture based on all-optical waveform and flat frequency comb generation for 100 Gbit/s optical access. The flat frequency comb generation provides an effective and costless way to generate all-optical OFDM signals and implement coherent detection in both downstream and upstream. Simulation results show robust and outstanding performance of the proposed system. 
