摘　　要：随着5G等网络应用的深入推进,承载业务的光缆总量还在不断增大。光纤作为网络传输的主要媒介,其在网运行质量直接影响到上层网络的健康性、可靠性和稳定性。光时域反射仪OTDR(Optical Time-Domain Reflectometer)是一种检测光纤是否存在断裂、接头耦合性不佳、介质非均匀性等缺陷的检测仪,主要包括用于临时测试的手持式便携型和24 h实时在线监测型两大类。面向光缆OTDR手持式测试仪设计通用型通信接口程序,建立一套基于SOR数据文件的通信流程和解析方法,针对实时在线监测型检测设备以SOCKET实现定制化的网络化接口程序,针对离散的OTDR光缆监测设备建立系统化的采集接口系统,实现了将多形态OTDR光缆监测的原始测试数据解析后集中推送到上层光缆质量应用分析系统的功能。该接口系统在某局的试点应用结果表明:接口运行稳定,应用效果良好,对光缆的运行监测具有现实意义。With the in-depth promotion of 5G and other network applications,the total number of optical cables carrying services is still increasing.Optical fiber is a major medium of network transmission.Its network transmission quality would directly influence the health,reliability and stability of the upper-layer network.Optical Time-Domain Reflectometer(OTDR),an instrument used to detect whether the optical fiber has broken,displays poor coupling of joints or heterogeneity,can be divided into two categories:handheld portable OTDR for temporary test and OTDR for 24-hour real-time monitoring.A universal type of communication interface program was designed and a set of communication procedures and analysis methods was established based on SOR data files for handheld portable OTDR.As for OTDR for 24-hour real-time monitoring,a set of network interface programs with SOCKET was customized,a systematic acquisition interface system was established for discrete OTDR optical cable monitoring equipment,which realized the ability to analyze the original test data of multi-modal OTDR optical cable monitoring and pushed them to the upper optical cable quality application analysis system.The interface system has been applied by a public authority and the results shows that the interface runs stably and has good application effect.It has practical significance for the operation monitoring of optical cable.
