Distributed Acoustic Sensing (DAS) systems detect strain changes and vibrations along optical fibers. This highly sensitive technology is used for monitoring critical infrastructure such as power cables, pipelines, or railroad tracks. 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. Vibration analysis is one of the proven methods in fault detection in a variety of dynamic components. 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. To this end, the. DAS technology transforms long sections of fiber optic cables into a high-density array of vibration sensors, providing exceptional spatial and temporal resolution for real-time monitoring of vibrations.
