摘　　要：利用OptiSystem软件,对高速光纤传输系统中三阶色散(TOD)导致的脉冲失真进行了仿真研究。分析了光脉冲信号通过光纤传输系统传输2000 km,不同的速率、占空比、脉冲形状和光纤类型对三阶色散的影响,同时比较了高斯脉冲和超高斯脉冲经过2000 km传输后的品质因数,发现高斯脉冲的品质因数优于超高斯脉冲的品质因数。通过仿真分析得出:当同时考虑群速度色散(GVD)和三阶色散的时候,标准单模光纤(SSMF)和啁啾光纤布拉格光栅(CFBG)组成的高速光纤传输系统性能表现较好。We analyze pulse distortions due to the fiber communication by using OptiSystem software third-order dispersion （TOD） in ultra-high-speed optical The effects of TOD are observed considering the variation of different factors such as bit rate, duty cycle, pulse shape and fiber type when pulse signals are transmitted through optical fiber communication system at a transmission distance of 2000 km. Meanwhile, we find that Q factor of Gaussian pulses is better than that of super-Gaussian pulses at a transmission distance of 2000 km. The simulation results show that the performance of a standard single-mode fiber chirped fiber Bragg grating （SSMF-CFBG） system is better in ultra-high-speed TOD effects are considered. application when both group velocity dispersion （GVD） and
