Advances in distributed vibration sensing for optical communication
This paper describes our recently proposed novel distributed vibration sensing (DVS) measurement technologies for visualizing the state of optical fiber in communication cables.
Unlike traditional point-type vibration sensors, DVS realizes continuous, real-time vibration monitoring and positioning along the entire length of the fiber, covering distances up to 60km per channel...
