In order to improve the transmission performance of optical fiber wireless communication system, a novel optical fiber wireless communication system based on phase modulator is proposed. Firstly, the principle of optical millimeter wave generation and its research status are analyzed. The advantages and disadvantages of various kinds of optical millimeter wave generation are pointed out. Then, a plurality of phase modulators are used to generate high frequency optical millimeter wave in parallel and a corresponding optical fiber wireless communication system is established. Finally, The performance of optical fiber wireless communication system was verified by simulation. The results show that the optical fiber wireless communication system in this paper effectively prolongs the signal transmission distance, has greater anti-dispersion effect, and reduces the signal transmission power cost.
