Title
(EN) Detecting fiber optic breaks using autonomous vehicles
Abstract
(EN)

In one embodiment, an autonomous vehicle receives a location of a fiber optic cable repeater of a fiber optic cable. The autonomous vehicle navigates the vehicle to the location of the fiber optic cable repeater and interfaces an optical time domain reflectometer (OTDR) of the autonomous vehicle with an OTDR port of the fiber optic cable repeater. The autonomous vehicle performs OTDR measuring of the fiber optic cable via the OTDR port of the fiber optic cable repeater, and sends a result of the OTDR measuring of the fiber optic cable to a supervisory device.
