摘要
针对安徽省电力系统EPON网络的特点及电力系统现有光缆监测技术特点,提出一种"OTDR+光开关+合波器+光反射器(终端过滤器)"光缆在线监测系统设计方案。EPON光缆在线监测系统能够实时监测光缆线路的性能变化,及时发现故障隐患,迅速定位障碍点,有效减少故障的历时,从而降低因温度和应力等因素带来的电力系统光纤通信网的故障发生。
For the characteristic of EPON network in Anhui power system,and the characteristic of current optical cable monitoring technology in power system,a design scheme of optical cable online monitoring system is proposed,in which the OTDR,photoswitch,optical multiplexer and optical reflector（terminal filter）are integrated. The optical cable online monitoring system based on EPON can monitor the performance variation of the optical cable lines in real-time,discover the potential failure timely,find out the failure location quickly,and reduce the processing time of the failure. The network failure of the optical fiber communications network in power system can be reduced,which is caused by temperature and stress.
