大客户光缆保护方式探讨及典型应用

Protection Mode of Key Customer Cable and Typical Application

因外力因素的干扰,大客户光缆线在运行中常常遭到破坏或通信受到干扰,不仅对客户的业务活动造成影响,而且对于通信公司光缆通信服务质量也是一种挑战。本文基于这一问题,通过对目前几种主流的城域网光缆传输物理双路由保护方式进行分析探讨,最终选定1/2分路器、1×2光开关和CWDM组成的互保传输方式,继而通过典型应用验证其可行性。

Due to the interference of outside factors, the optical cable of key customers is often damaged or the communication is interfered, which not only affect the customer＇s business activities, but also challenges the cable communication service quality of communication company. In this paper, based on this problem, several common metropolitan area network optical cable transmission physical double routing protection methods are discussed. Finally the 1/2 branching device, 1 x2 optical switch and CWDM mutual protection transmission is selected, and its feasibility is verified through typical applications.
