Cable optical fiber temperature measurement system
1、 Demand analysis
The cable optical fiber temperature measurement system is laid along the cable. Supported by advanced technology, it can detect the temperature change along the cable in real time, detect the continuity of the cable information, and dynamically master the cable information. Through the real-time detection of the cable temperature at multiple points, it can give an early warning in time when the cable goes out of line and prevent accidents. And the device can determine the cable load change according to the cable temperature, and optimize the cable configuration reasonably, thus improving the cable efficiency.
2、 Working principle
The cable optical fiber temperature measurement system can quickly and systematically measure the temperature of the cable and quickly locate the fault point. It can dynamically monitor the temperature change of the optical cable within a range of more than ten kilometers, with a temperature resolution of 0.1 ℃ and positioning. The device alarm system can be flexibly set by the management personnel, which can store the detection records for a long time. The optical signal is used to detect the optical cable, which is simple to install and can be directly installed on the surface of the optical cable.
