Do you know the working principle and characteristics of active vibrating optical fiber?

Feitian Laser Active Vibrating Optical Fiber is a perimeter anti-intrusion technology based on optical fiber sensing technology. Its distinctive feature is that it uses optical fiber as a sensor to sense external intrusion information. It is widely used in government, Electric power, military, residential areas and other fields to achieve the purpose of security prevention.

Working principle: Based on optical fiber sensing technology, optical fiber is used as a sensor to sense external intrusion information. The sensing cable, reflector, and all-fiber interference module together form an interference structure, and the fiber perimeter achieves the acquisition of disturbance information through the interference structure. Light enters from the input port of the all-fiber interference module. The light processed by the optical fiber interference module is input to the sensing cable. After being reflected by the reflector at the end of the sensing cable, it re-enters the sensing cable and finally returns to the all-fiber interference module. module.

System advantages

Independent alert

Each defense zone analyzes signals independently and operates independently. Alarms in different defense zones do not affect each other when intrusion occurs

The detection rate is 100%

Cables are used as sensing units, and computers are used to collect and identify data to achieve long-distance and large-scale defense zone detection. The detection rate is 100%.

Super environmental adaptability

The background software can set parameters for the surrounding environment, adapt to changes in the external environment, and is suitable for harsh environments such as strong winds, rain, and low temperatures.

It is not subject to electromagnetic interference or electromagnetic radiation, and is not afraid of lightning strikes, lightning and other severe weather
