Distributed optical fiber vibration detector

Based on narrow linewidth laser backscatter self-coherent demodulation technology and fiber laser radar technology, distributed optical fiber vibration detection system uses optical fiber as a vibration sensing element to achieve distributed optical fiber vibration detection, which can be widely used in oil and gas pipeline leaks, power cables Early warning of third-party excavation; early warning of anchor damage of submarine communication optical cables and submarine photoelectric composite cables; perimeter intrusion monitoring in key areas such as national borders, military camps, ammunition depots, and banks.

Key technical indicators:

Detection distance: 50km; positioning accuracy: 10 meters

Application scenario:
