摘　　要：信息在高速、长距离传输时,色散、非线性效应等对系统的影响加重,使用新型光调制技术可以减少传输过程中带来的损伤。在Opti System软件中搭建40Gb/s仿真平台,结合Matlab软件对常用强度调制码和相位调制码进行对比分析,重点研究其色散容限及非线性效应,将性能较好的IRZ码和DQPSK码结合起来,组成新型调制码IRZ-DQPSK,并研究其性能。When the information is transmitted at the high-speed and long-distance system, the effect of dispersion and nonlinear effect is aggravating. Using new optical modulation technique can effectively reduce the damage that caused during transmission. The 40Gb/s transmission system will be built in OptiSystem simulation platform, and the common code for intensity modulation and phase modulation will be simulated with OptiSystem and Matlab Software. The system mainly focuses on the dispersion tolerance and non-linear effects of signals. After that, the better performance code of IRZ and DQPSK will be built up the new composi- tion modulation code IRZ-DQPSK, and to study their properties.
