【摘要】 随着光通信技术的发展,各种现有的单模光纤已不能满足宽带光传输密集波分复用(DWDM)系统传输的要求,S C L三波段传输新型单模光纤是在1460～1625nm的波长范围内具有足够大的色散以抑制四波混频效应、交叉相位调制等非线性效应,又使色散及斜率尽可能低,从而使色散管理成本降到最低的新型单模光纤.我们设计和计算了这种新型的光纤的结构并对其性能参数进行了分析和讨论.更多还原

【Abstract】 Along with the development of optical communication, all kinds of optic fiber in existence can not meet the requests of DWDM, but S+C+L band new single mode fiber has enough dispersion at 1 460～1 625 nm to restrain FWM and XPM nonlinear effects. At the same time, its dispersion and slope is very low that can reduce the cost of dispersion management. We designed the structure of this kind of fiber and analysed its properties.更多还原
