Caractéristiques de Vibration Fiber Optic Detection and Alarm System

1) The defense zone adopts ordinary optical cables for lightning protection and anti-interference
All sensors are ordinary optical cables that are not affected by electromagnetic interference or radiation, effectively avoiding damage to the system caused by lightning strikes. They do not interfere or affect various signal fields such as electromagnetic, radio frequency, wireless signals, and high-voltage electrostatic fields.
2) Modular structure supports hot swapping, making it easy to expand to 16 defense zones
Adopting a fully modular design, each defense zone analyzes signals independently and operates independently. When someone invades from different defense zones at the same time, the invaded defense zone can alarm simultaneously without affecting each other, and supports multiple defense zones to alarm simultaneously.
3) No power supply required for the entire defense zone, low passive energy consumption
Applying vibration sensing optical cables (ordinary optical cables) to the perimeter intrusion prevention field, the entire security perimeter does not require power supply, which not only improves system reliability and anti-interference ability, but also reflects the characteristics of energy conservation and environmental protection, effectively improving system availability and service life.
4) Patent exclusive single zone sensitivity adjustment, intelligent recognition, and low false alarm rate
The sensitivity and other alarm parameters of each defense zone in the system can be adjusted separately without affecting each other, to adapt to different peripheral environments, such as weather changes, plant growth, animal activity, and vehicles on nearby roads.
5) Suitable for harsh environments such as heavy rain and low temperatures.
Due to the use of optical cables as sensing media and powerful backend software to set parameters for the surrounding environment, the system has the ability to adapt to changes in the external environment.

Functional description of vibration fiber optic detection and alarm system quotation
The vibration fiber optic cable alarm processing unit sends coherent mode laser to the sensing fiber optic cable, which is installed on the iron wire mesh or other perimeter fiber optic fences. When illegal intruders climb, climb or interrupt the iron wire mesh, it will cause vibration, which will change the transmission mode of light. Part of the characteristics of the transmitted light in the vibration fiber optic cable will change. After signal acquisition and analysis, the vibration fiber optic cable alarm processing unit can detect changes in the characteristics of the light (i.e. attenuation, phase, wavelength, polarization, mode field distribution, and propagation time). By analyzing the characteristics of the changing waveform through software, the true situation of the event can be distinguished, thereby achieving the effect of “intrusion pattern recognition”, issuing alarm signals, and realizing the fiber optic alarm function.
