一种光链路监控和诊断系统的设计研究

An Optical Link Monitoring and Diagnostic System Design Study

光链路故障诊断是通信运营商运维工作的难点，本文提出一种光链路监控和诊断系统的设计方案，采用了OTDR光学检测和双端光功率检测相结合的检测手段，以OLT设备为依托，提供数据分析和门限告警功能，能实时监控光链路，方便准确的定位链路故障，提高了运维效率，降低了运维成本。

Optical communication link failures diagnosis is operator of the difficult operation and maintenance work,this paper presents an optical link monitoring and diagnostic system design,using a double-ended OTDR optical detection and optical power detection means detects a combination to OLT equipment,relying on data analysis and threshold alerting,real-time monitoring of optical links,to facilitate accurate positioning of link failures and improve the operation and maintenance effficiency, reduce operational costs.
