摘要
对NRZ、RZ和CS-RZ码等三种码型在高速准线性传输系统中的性能进行了分析。通过对设计出相应色散管理方案的仿真,对其色散容限、抗非线性效应、抗噪声和抗偏振模色散性能进行对比分析。根据系统设计CS-RZ码的预色散补偿、后色散补偿和对称色散补偿等三种色散管理方案,并对三种方案的最大Q值进行残余色散优化,为现实系统的设计提供参考价值。
In this paper,NRZ、RZ and CS-RZ code in the high-speed quasi-linear transmission systems performance have been analyzed.Simulation of the corresponding dispersion management program has been designed.It makes an analysis of dispersion tolerance,anti-nonlinear effect,anti-noise and anti-polarization mode dispersion performance.We design management program of pre-dispersion compensation,post-dispersion compensation and symmetrical dispersion compensation for CS-RZ code,which makes optimization of residual dispersion for the best value of the three management programs and provide a reference value for the design of the actual system.
