本文分析了DWDM系统中XPM和FWM效应随信道间距变化的关系
并提出了大容量长距离DWDM系统仿真的解决方案.严格的数值计算表明
在信道间距为50GHz的DWDM系统中
当信道数大于9(SMF)和15(NZDSF)时中心信道的Q值基本不再随信道数增加而变化.这一结果对于大容量长距离DWDM系统的实验设计有重要的指导意义.
The relation between channel spacing and effect of XPM and FWM in DWDM system was analyzed
and a new solution for simulation of high speed and long haul DWDM system was derived.In further numerical calculation
it was demonstrated that Q of center channel wasn't sensitive to increase of channel number when channel number is larger than 9 (in SMF) and 15 (in NZDSF) in DWDM system with 50GHz channel spacing.This result can be used in experimental design of DWDM system.
