A Novel Radio over Fiber System for Long Haul Single-Mode-Fiber Transmission

We have proposed and demonstrated a novel architecture of a radio over fiber (RoF) system in this paper. In this downlink system, the base band data signals are carried by the optical millimeter-wave generated at the central station and converted to the electrical RF signal by a converter at the base station before we distribute them through antenna. Here we generate and transmit the optical millimeter-wave by using external modulation technique and carrier suppression method. The performance is investigated by the good eye diagram and the significantly low BER at different lengths of the single mode fiber (SMF).
