    摘要： 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.

    摘要： A method for monitoring the torsion of a cable includes the steps of: providing a cable having an outer surface and extending along a longitudinal direction, the cable being provided with at least one identification tag, preferably an RFID tag, arranged in a tag angular position in a cross-sectional plane taken transverse to the longitudinal direction, the at least one tag storing a tag identification code and being capable of transmitting a tag electromagnetic signal; interrogating the at least one identification tag to receive the tag electromagnetic signal, and detecting the tag electromagnetic signal, wherein the step of detecting the tag electromagnetic signal includes the step of reading the tag identification code and determining the tag angular position of the at least one identification tag. A torsion monitoring system of a cable includes at least one identification tag.
