摘　　要：利用Optisystem仿真软件,对40Gb/s单信道传输系统中归零(RZ)调制和非归零(NRZ)调制两种格式进行仿真,并且对基于RZ调制格式下的单信道40Gb/s的色散补偿进行了仿真,比较了前置补偿、后置补偿和对称补偿的传输性能。仿真结果表明:在长距离传输时RZ调制格式优于NRZ调制格式,三种补偿方式中对称补偿效果最优。This paper do a simulation at 40Gb/s single channel transmission system in RZ-modulation and NRZ-modulation by using Optisystem simulation software.In addition,a simulation of dispersion compensation in 40Gb/s single channel has been done based on RZ-modulation,compared the transmission performance of pre-compensation,post-compensation and symmetric-compensation.The simulation results show that RZ-modulation is superior to NRZ-modulation in the long-distance transmission,and symmetric-compensation format has a better compensation performance than the others.
