| 摘 要： | 提出了一种有效抑制零级中心频带方案,并证实了该方案的可行性,给出了基于该方案的单工Radio over Fiber (RoF)通信系统.通过光通信系统软件Optisystem5.0仿真模拟结果显示：光源发送功率为5 dBm,途中无光放大,24 GHz的超高频微波信号在色散系数为20 ps/nm/km、衰减系数为0.25 dB/km的单模光纤中传输,系统码元传输速率可达5 Gbit/s、传输距离15 km以上.

| Abstract: | A scheme of effective restraining zero rank central band was proposed and demonstrated,using electronic-optical frequency modulation(EO-FM).And a simplex system RoF communication system was presented based on the above technique in the article.Optical system software-Optisystem5.0 is adopted in the simulation.The simulation results show that the simplex-directional 5 Gbit/s data modulating in UHF microwave with 24 GHz can be successfully transmitted over a 15 km-length SMF with 5 dBm transmitted power,20 ps/nm/km dispersion,and 0.25 dB/km attenuation. |
