OLM Network Management System

With the software function of the monitoring system, it provides powerful real-time, online, and automatic monitoring function of OTDR optical fiber, GIS map auxiliary resource management function, multiple alarm reporting mode, provides an effective means of monitoring and maintenance of optical cable network for relevant departments, and assists managers to master the quality of optical cable network. Greatly improve operation and maintenance performance and communication quality.

1. Test management: can provide roll call test, cycle test, alarm test, and other monitoring modes

2. Fault location: according to the node distance and cable winding length of optical cable routing, the most direct and specific information on fault repair is provided.

3. Decision support information: provide core line deterioration analysis, time deterioration analysis, fault type and cause statistics, and other decision support functions.

4. User level management: multiple access systems, different levels of user roles access different functional modules.

5. Graphical management: using the GIS platform system to realize the visual management of optical cable, pipeline, ground well, machine building, and other resources.

6. Historical data query: with complete historical data, convenient and fast query.

7. Timely fault alarm: through SMS and field sound and light and other alarm methods the first time to notify the maintenance personnel.
