SYSTEMS AND METHODS FOR DISTRIBUTED FIBER OPTIC SENSING OVER LIVE FIBERS

Abstract: a device may provide a first optical signal to an optical fiber network via a live fiber cable, the first optical signal including a distributed fiber optic sensing optical signal, and may receive, from the optical fiber network, a second optical signal, based on the first optical signal and via the live fiber cable. the device may determine whether a vibration event associated with the live fiber cable is detected based on the second optical signal, and may perform one or more actions based on whether the vibration event associated with the live fiber cable is detected.
