Abstract

We propose and experimentally demonstrate a novel architecture for OFDM-PON system. The down link is based on single side band OFDM modulation while the up link makes use of the carrier information retained in another side band to intensity modulate the data. The downstream transmission will be demonstrated experimentally to exceed 10Gb/s using 4-QAM while the upstream transmission will exceed 2.5-Gb/s using ASK modulation and Time Division Multiple Access (TDMA). This architecture can perfectly overcome the Rayleigh scattering effect. It has been proved the transmission for both directions can reach 10km without bit error. And if the scattering effect is considered, the power penalty will be less than 0.8dB for downlink and 1.8dB for uplink.
