Distributed Vibration Fiber Optic Sensor-Buried Ground

The buried vibration optical fiber perimeter detection system is a passive security early-warning device built on distributed optical fiber sensing technology. The specially designed sensing cable is buried under soil, gravel or turf. By detecting changes in the phase/intensity of light transmitted through the fiber, it accurately identifies intrusion behaviors such as treading, digging, and vehicle rolling, realizing dead-angle-free perimeter monitoring and location-based alarms. The system requires no on-site power supply, features strong concealment, adapts to complex terrains, and is an ideal perimeter protection solution for high-security-level scenarios.

Core Advantages

1.Passive Design, Safe & Explosion-Proof: The sensing cable is fully passive with no spark risk, suitable for flammable/explosive and strong electromagnetic interference environments
2.Concealed Installation, Strong Anti-Destruction: Buried laying does not affect the landscape, hard to be detected or destroyed by intruders, with a false alarm rate below 1%
3. Long Lifespan, Low Maintenance Cost: The optical fiber is corrosion-resistant and anti-aging, with a service life of over 20 years and almost no post-installation maintenance required
4. All-Terrain Adaptation, No Monitoring Blind Spots: Can be laid along irregular perimeters, adapting to complex terrains such as mountains, plains, and rivers, realizing full-line dead-angle-free monitoring

Application

1.Critical Infrastructure Protection: Preventing third-party construction damage, illegal digging and oil theft along oil/gas pipelines, communication cables and power facilities
2.Border/Frontier Security: Remote, complex-terrain border lines, replacing traditional fences with concealed intrusion monitoring
3.Flammable/Explosive Site Protection: Perimeter early warning for high-risk sites such as oil depots, ammunition depots and chemical plants where electric sparks are prohibited
4.Park/Factory Security Management: Anti-intrusion and illegal trespassing early warning for large industrial plants, logistics parks and data centers
