摘要
随着密集波分复用技术和高速数字交换技术的广泛应用,密集波分复用系统中的光保护技术显得日益重要。文章介绍了目前光通信网络中常用的光纤自动切换保护技术和冗余波长实现光保护技术,并结合实际案例对其光保护技术在实施过程存在的一些问题进行了分析,最后提出了相应的改进建议。
With the extense application of dense WDM technology and high speed digital switching technology,the light protection technology in DWDM system has been playing an increasingly important role.This paper introduces the optical fiber automatically switched protection technology and the realization of redundant wavelength protection technology.The existing problems in the implementation of the light protection technology are analyzed and finally some corresponding suggestions are put forward for improvement.
