OTS
The distributed optical fiber temperature sensing system (OTS) is a device which can conduct real-time and continuous temperature measurement. By collecting the signal light returned due to spontaneous Raman backscattering of pulsed light in the sensing optical fiber, the system can accurately obtain the spatial temperature distribution information and position information according to the principle of optical time-domain reflection and the working principles of radar, which can be widely used in fire alarm of cable trench, municipal pipe, oil and gas pipeline, OPPC partial discharge monitoring and other scenarios.
