    摘要： A method for the direct measurement of large strains in ropes in situ using a plastic optical fiber, for example, perfluorocarbon or polymethyl methacrylate and Optical Time-Domain Reflectometer or other light time-of-flight measurement instrumentation. Protective sheaths and guides are incorporated to protect the plastic optical fiber. In one embodiment, a small rope is braided around the plastic optical fiber to impose lateral compressive forces to restrain the plastic optical fiber from slipping and thus experience the same strain as the rope. Methods are described for making reflective interfaces along the length of the plastic optical fiber and to provide the capability to measure strain within discrete segments of the rope. Interpretation of the data allows one to calculate the accumulated strain at any point in time and to determine if the rope has experienced local damage.

    摘要： An electrical cable having a holding member arranged within the cable for an optic fiber, which can be used for temperature sensing and/or communications. The holding member can replace one or more strands of the cable, be placed inside an interstice of the cable, be placed in between various layers of the cable, or placed in the jacket of the cable. If desired a strength member may be adjacent to and/or attached to the holding member to provide additional protection for the optic fiber. The cable can be produced through the addition of a planetary strander device to a wire assembly apparatus.
