| 摘 要： | 文章设计了一个基于频率间插复用的DWDM-ROF(密集波分复用—光载无线)系统,使每个信道载波与边带之间的空闲频段得到利用,从而提高了DWDM-ROF系统的频谱利用率.同时,为该系统设计了一种基于FBG(光纤布拉格光栅)的新颖的解复用器.数据传输的仿真实验不仅验证了该方法的可行性,还显示出了该系统具有良好的抗信道串扰能...

| Abstract: | A frequency interleaving-based DWDM-ROF system is designed,in which the idle frequency bands between the carrier and sidebands of each channel is utilized,thus improving the system spectral efficiency.At the same time,a novel demultiplexer based on Fiber Bragg Grating(FBG) is designed for this system.The simulation results in data transmissions not only verify the feasibility of the proposed method,but also show that the system is well resistant to interchannel crosstalk. |
