浅谈移动通信基站接入光缆的避雷防护

移动通信的基站遍布山顶、楼顶等相对位置较高的地点，极易遭受雷击，一般都对基站的电源供电系统、铁塔及天馈线系统采取了良好的避雷防护措施。但在光缆线路接入基站的过程中，安全接地往往被忽视，光缆线路遭雷击的情况时有发生。首先针对直埋、架空、管道三种基本的光缆敷设形式进行光缆的落雷原因分析。再分别论述三种光缆敷设形式的具体防雷措施，然后论述光缆防雷接地系统的工程实施工艺、测试指标及工程建设中应注意的问题。

Discussion on the Lightning-Protection of Access Optical Cable in Mobile Base Station

This article first analyzesthe causeof lightning-stuck on fiber optic cable which are laid in the he three basic forms ofdirect burial, aerial and pipeline.Then it discusses the specific lightning protection measures for each kind of fiber optic ca- ble laid.At last it discusses the problems that should be pay attention to in project implementation process, Test indicatorsand construction projects of fiber optic cable lightning protection and grounding systems. This article aims at providing design and construction reference for fiber optic cable access of future mobile communication base stations.
