波分复合技术能够充分的挖掘光纤的信号传输能力。从目前的使用效果来看,波分复合技术对于光线的传输能力的提升效果可达到几倍到几十倍,这与理论上光纤的通信容量是无限的也是十分符合的。本文对波分复用技术进行了简单的介绍,分析了波分复用技术的应用现状及前景,阐述了单光纤非干扰性传输、远距多频传输、本地节目插入等多种技术。
WDM technology can fully tap the signal transmission capacity of optical fiber. From the current use of the effect of view, WDM technology for light transmission capacity to enhance the effect of up to several times to dozens of times, which is theoretically optical fiber communication capacity is unlimited and is also very consistent. In this paper, the WDM technology is briefly introduced. The application status and foreground of the WDM technology are analyzed. A variety of technologies such as single-fiber non-interference transmission, remote multi-frequency transmission and local program insertion are described.
