Distributed Optical Fiber Vibration Sensing System 50km Submarine Cable Damage Monitoring
Distributed Optical Fiber Vibration Monitoring System
DVS Description
Optical Fiber Vibration Sensing System is based on the optical fiber RAYLEIGH scattering principle. It uses the SMF to be the slightly vibration sensing part and also cooperate with the optical fiber vibration main detection controller, the system can real time detect the vibration signal of the optical fiber.
Through the monitor software analysis, the accurate positioning have been made by the vibration source, the type of the vibration signal can be divided, then the system will emit the alarm signal.
Distributed optical fiber vibration sensing system can be used to the anti-damage detection of long distance pipelines, such as oil and gas pipeline, liquid pipeline, pipe gallery, national defense border surveillance and invasion control, coal mine fire collapse rescue workers location, high-speed railway damage and personnel.
