System Introduction
The fiber optic perimeter intrusion monitoring system realizes fiber optic vibration sensing and monitoring based on the basic principle of Rayleigh scattering, combined with φ-OTDR (Phase Sensitive Optical Time Domain Reflection) technology and signal analysis and processing algorithms.
The system uses ordinary single-mode fiber as the sensor, which is cheap, convenient and real-time, and has a long service life.
Fiber-optic perimeter intrusion monitoring system is able to detect 40km, or even longer distance fiber optic cable. It can quickly monitor the disturbance of the whole fiber optic cable and locate the disturbed position in real time, with a positioning accuracy in the range of 5 meters.
System features
1, G652D common single-mode fiber as a sensor, cheap, easy construction, long service life;
2, long monitoring distance, can be more than 40KM monitoring distance, positioning accuracy within 5 meters;
3、Unique vibration monitoring identification algorithm, can effectively filter false alarm information.
System Composition
Fiber-optic perimeter intrusion monitoring system, using the DVS integration module to build, will greatly save your time, DVS integration module internal integration of narrow linewidth laser, AOM acousto-optic modulator, EDFA & Raman amplifier, balanced detector and so on.
Together with a DVS high-speed acquisition DAQ, you can realize the hardware preparation of DVS system.
