摘要
本文首先介绍了某地级市有线市县传输网的拓扑结构和业务类型,然后阐述了光线路保护系统的组成和原理,最后提出了市县传输网光线路保护的设计方案。该方案从光缆长度估算、光功率调整、色散补偿计算等方面入手,详细论述了三个方面的设计方法。
This paper first introduces the topological structure and service types of the cable transmission network in a certain prefecture-level city,then elaborates the composition and principle of optical fiber line protection system,and finally proposes a design scheme of the optical fiber line protection system for transmission network between city and county.The design methods of optical fiber length estimation,optical power adjustment and dispersion compensation are discussed in detail in the scheme.
