波分复用(WDM,Wavelength Division Multiplexing)、光纤接入网和全光网技术是当前发展较快的几项光纤通信技术,其中波分复用技术是在一根光纤上同时利用多个波长进行传输,发展前景很好.光纤用户接入网的发展将加速光纤到户的实现.全光网目前存在一些需要解决的技术问题,美国、日本和欧洲一些国家已建立全光网试验网.目前使用最多的G652单模光纤的缺陷限制了其进一步发展,G653色散位移光纤由于四波混频效应不适于在波分复用系统上的应用.C655非零色散位移单模光纤有较好的发展前景.用户光缆具有芯数多,采用带状结构和塑料光纤等特点.
Wavelength Division Multiplexing (WDM), optical access network and all-optical network technology are currently several rapid development of optical fiber communication technology, which is the wavelength division multiplexing technology in a fiber using multiple wavelengths And the development prospect is very good.The development of optical subscriber access network will accelerate the implementation of FTTH.At present, there are some technical problems that need to be solved in the optical network, and some optical networks have been set up in the United States, Japan and some European countries. The defects of G652 single-mode optical fiber, which is currently the most used, have limited its further development, and the G653 dispersion-shifted optical fiber is not suitable for the WDM system because of the four-wave mixing effect.C655 non-zero dispersion shifted single-mode optical fiber has better Development prospects. Cable users have a number of cores, using ribbon structure and plastic optical fiber and so on.
