AbstractA hybrid cable of substantially uniform cross-section for concurrently carrying an electrical signal and an optical signal. The cable includes a metallic conductor disposed at the center of the cable for carrying the electrical signal. The cable also includes a resilient buffer tube and an optical conductor for carrying the optical signal positioned inside the tube and having an outside diameter smaller than the inside diameter of the tube so that the optical conductor is movable inside the tube. A metallic shield surrounds the metallic conductor and the tube. The metallic conductor and the shield are coaxial. The cable also includes an electrically insulative resilient outer jacket so that the cable gives the appearance of and taps as a conventional coaxial cable but additionally can transmit an optical signal. A method of using the hybrid cable is also disclosed.
