一种定位odn网络段故障的方法及系统

Method and system for positioning ODN (optical distribution node) network section faults

Abstract

本发明涉及光通信技术领域,尤其涉及一种定位ODN网络段故障的方法及系统,该方法应用于包括有顺次连接的OLT设备、P个交接箱、N个分光器、M个家庭网关的网络中,OLT设备通过主路光缆连接P个交接箱,P个交接箱通过分支光缆连接N个分光器,N个分光器通过皮线光缆连接M个家庭网关,M>N>P,P为正整数,包括如下内容:采集经由OLT设备上报的告警信息或由P个交接箱、N个分光器、M个家庭网关定时上报的故障信息;对所述告警信息或故障信息进行分析,从而定位故障,进而能够对ODN网络段故障进行精确定位。
The invention relates to the technical field of optical communication, in particular to a method and a system for positioning ODN (optical distribution node) network section faults. The method is applied to a network comprising an OLT (optical line terminal) device, P cross-connecting boxes, N optical splitters and M home gateways which are sequentially connected, the OLT device is connected with the P cross-connecting boxes through main optical cables, the P cross-connecting boxes are connected with the N optical splitters through branch optical cables, the N optical splitters are connected with the M home gateways through rubber-covered optical cables, M>N>P, and P is a positive integer. The method includes the steps: acquiring alarm information reported by the OLT device or fault information regularly reported by the P cross-connecting boxes, the N optical splitters and the M home gateways; analyzing the alarm information or the fault information and accordingly positioning the faults. The ODN network section faults can be accurately positioned.
