摘    要:提出并模拟证明了基于两个电光相位调制器实现抑光载波双边带(Radioon Fiber,RoF)双工传输系统设计方案.通过改变电光相位调制器的最大相偏量,实现了抑光载波双边带信号传输——使通信带宽加倍,而且很好地控制上下行传输信号的误码率.仿真模拟结果表明,发射功率为3dBm的光信号在无放大、色散系数为20psj(nm·km)、衰减系数为0.25dB/km的SMF-28单模光纤中传输时,其超高频RF调制信号的频率可达24GHz,数据码元传输速率可达2.5Gbit/S,传输距离40km以上.

关 键 词:电光相位调制  抑光载波双边带调制  光学毫米波  RoF  无线通信网络

Abstract:A bi-directional ROF system based on double-sideband with optical carrier suppression(DSBOCS) scheme to generate optical millimeter-wave signal via electronic-optical phase modulation(EO-PM) was demonstrated.The communicated bandwidth could be doubled to realize Ultra Width Band & Ultra High Frequency(UHF) communication via phase modulation.The BERs of downlink and uplink via adjusting the phase deviations of the phase modulators could be successfully controlled.The simulation result shows that the bi-direc...
