摘要
为了提高频谱资源的利用率,缓解因色度色散和偏振模色散引起的符号间干扰,引入一种新的光调制技术。通过将正交频分复用技术(Orthogonal Frequency Division Multiplexing,OFDM)应用于光纤通信中,构造出高速率、大容量、低成本的光传输系统。该方法与传统的光通信技术相比,具有更强的系统抗色散能力。利用OptiSystem软件构建仿真系统,分析了光正交频分复用(Optical Orthogonal Frequency Division Multiplexing,O-OFDM)技术的抗色散性能。根据仿真结果可得出,光正交频分复用技术在高速超长距离的光纤通信中,具有很好的应用前景。
A new optical modulation was introduced.Based on the application of orthogonal frequency division multiplexing（OFDM） in optical fiber communication,an optical transmission system was constructed.Compared with the traditional optical communication technology,this system has the stronger ability to resist dispersion of optical fiber.With the OptiSystem software,a simulation was done to analyze the resisted dispersion performance of the optical orthogonal frequency division multiplexing（O-OFDM） technique,and the results show that O-OFDM has the very good application prospects for ultra-long haul and the high-speed optic-fiber communications.
