Abstract
An extendable fiber optic cable includes an inner tubular core, a viscous l received in the tubular core, a plurality of optical fibers suspended in the gel, reinforcing fibers which are braided around the inner core, and an elastomeric outer cover which is received over the reinforcing fibers. The cable is first formed in a straight configuration and then formed into a plurality of coiled segments wherein adjacent coiled segments are wound in alternating directions, i.e. clockwise, counterclockwise, clockwise, etc. Straight segments of wire are provided between the coiled segments wherein the cable is stretchable up to 50% of its relaxed length. The alternating coil segments prevent the cable from twisting and transmitting torque forces to the optical fibers.
