Vibration fiber when the fiber is subjected to vibration, some of the characteristics of the light transmitted in the fiber will change, through the configuration of special sensing equipment, after the signal acquisition and analysis, you can detect the characteristics of the light (i.e., attenuation, phase, wavelength, polarization, mode field distribution and propagation time) changes. Changes in the characteristics of light are processed through special algorithms and analysis of the alarm controller to distinguish between third-party intrusion behavior and normal interference, and to realize the alarm function.
Vibrating fiber optic systems are easy, flexible and safe to lay because they are easy, flexible and can be highly concealed. Easy to integrate into the surrounding environment, can be in a variety of outdoor harsh natural environments in the normal twenty-four hours of preventive work.
