Distributed acoustic sensing: the future of urban asset monitoring

Anywhere that there is a fiber optic cable and this acoustic energy touches the fiber optic cable….Every city has that underground layer…This fiber optic itself is an IoT device….an interrogator box…to light up this fiber optic cable to know what’s happening…a smart road which lets the road reciprocate the activity of smart vehicles. You can use a fiber optic cable to understand the movement of traffic, the direction of traffic, whether there is a traffic jam. Another application is for monitoring water consumption….If you have a fiber optic cable just next to it, DAS can tell you if there’s a leak, if there’s excavation activity happening nearby that has damaged the pipe - and this is real time….DAS is a great support mechanism for municipalities
