Abstract
A fiber optic cable has a central strength member formed by a wire with helical grooves in each of which is laid an insulated optical fiber. Steel wires are wound over the strength member plus fibers with the direction of lay of the wires opposite to that of the helical grooves so as not to crush the fibers. Also described is a jointing technique for a pair of such cables.
