Introduction to Optical Cable Vibration Alarm
The Vibration Fiber Optic Perimeter Alarm System is a high-precision intrusion detection solution used in critical infrastructure such as chemical storage facilities, refineries, and secured industrial zones. Unlike traditional point-type vibration sensors, DVS realizes continuous, real-time. Fiber optic vibration sensors that use existing fiber optic cables laid for communication have the advantage of being able to collectively and accurately measure vibrations over a wide range along the cables1), 2), and in recent years, they have been attracting attention as a means of environmental. However, lack of experimental data on actual machinery in comparison to test bench devices, has made it difficult for a reliable fault detection and lifetime assess-ment. It achieves precise positioning through the optical time domain reflectometry (φ-OTDR), combined with a backend data analysis and processing odule, enabling effective monitoring of vibrations.
