摘要

为研究高速光通信系统中的四波混频效应,基于OptiSystem搭建了8×10 Gb/s高速大容量传输系统中的四波混频噪声评估模型。根据ITU-T G.692工程指标要求,围绕信道间隔和色散管理,提出了两种区别于传统频率等间隔系统的改进方案,分别研究其对四波混频噪声的作用效果,第一种方案是两头大、中间小的部分等信道间隔,第二种方案是在第一种方案的传输链路中设置了DCF色散补偿系统,仿真结果表明两种改进方案均能有效地抑制四波混频效应,且第二种方案的效果更好,其传输距离和信道Q值明显增大,最高Q值可达30.0。
        In order to study the four-wave mixing effect in high-speed optical communication system,a four-wave mixing noise evaluation model for 8 × 10 GB/s high speed and large capacity transmission system is built based on OptiSystem. According to the requirement of ITU-T G.692 engineering index,around channel spacing and dispersion management,two kinds of improved schemes are proposed,which are different from the traditional frequency equal interval system,and their effects on four-wave mixing noise are studied respectively. The second scheme is to set DCF dispersion compensation system in the transmission link of the first scheme. The simulation results show that the two methods are improved. The scheme can effectively suppress the four-wave mixing effect,and the second scheme has a better effect. The transmission distance and channel Q value are obviously increased,and the maximum Q value can reach 30.0.
