Paper Abstract

We have experimentally investigated a full-duplex radio-over-fiber system transmitting 2.5-Gbit/s orthogonal frequency-division multiplexing (OFDM) signals with a 40-GHz optical millimeter wave as downlink. Meanwhile the central can be reused wavelength as the uplink connection for transmitting 2.5-Gbit/s on-off keying (OOK) signals. By experimentally comparing the transmission performance of OFDM downstream and OOK upstream signals, it can be seen that the power penalty for the downstream signals is about 1 dB at a bit error rate of 10−3 after transmission over a 50-km standard mode fiber. However, the power penalty for the upstream signals is less than 0.5 dB at a bit error rate of 10−9 after transmission over the same distance.
