Abstract

Simultaneous wired and wireless link services in a novel optical line terminal for orthogonal frequency-division multiplexing (OFDM)-wavelength- division-multiplexed passive optical network compatible with radio-over-fiber system is proposed and experimentally demonstrated. In the optical line terminal, optical carrier suppression modulation scheme is used to generate a 40-GHz optical millimeter-wave (mm-wave). 2.5-Gb/s OFDM signal is carried by the 40-GHz optical mm-wave. In the base station, we can provide simultaneous wired and wireless services. The downstream OFDM lightwave can be reused to carry 2.5-Gb/s on-off Keying nonreturn-to-zero (OOK-NRZ) upstream data without erasure of the downstream data.
