Summary:A method of measuring the length of an electric cable, includes providing an electric cable having a cable length and including a cable neutral axis, and a fiber unit longitudinally extending along the cable and including an optical fiber arranged substantially along the neutral axis, wherein the optical fiber is mechanically coupled with the cable; injecting an optical signal into the optical fiber; detecting back-scattered light from the optical fiber responsive to the injected optical signal; analyzing the detected back-scattered light as a function of time so as to determine the length of the optical fiber, and deriving the cable length from the length of the optical fiber.
