Dt-m series OPGW vibration online monitoring system adopts distributed optical fiber vibration sensing technology to detect the distributed vibration signals of overhead lines in real time, so as to realize the detection and monitoring of the core and key status of overhead OPGW lines. It is the necessary infrastructure for the preventive maintenance of OPGW lines, and can effectively guarantee the long-term and reliable operation of OPGW lines.

Advantages of the system:

1、 Distributed, long-distance detection:

2、 Simple structure: only one single-mode optical fiber in OPGW or OPPC is used for field components, which has both sensing and signal transmission functions

3、 Rapid deployment: portable and reliable system installation

4、 Strong environmental adaptability: the system is not affected by weather and other factors, and can work all day

Technical features:

   The system is mainly composed of detecting optical fiber, distributed optical fiber vibration sensor and monitoring host. The detection optical fiber is a single-mode optical fiber inside OPGW or OPPC; the distributed optical fiber vibration sensor and monitoring host are set in the monitoring room at one end of the overhead line. The monitoring host is PC, which runs the calculation and monitoring process, provides the monitoring view, and can be transmitted to the monitoring center or accessed remotely through the communication network.
