13. A method of performing a coiled tubing application at a location in a well at an oilfield, the method comprising:
pumping a fiber optic cable through a flow path of a coiled tubing;
physically coupling a downhole tool to the coiled tubing;
communicatively coupling a polymer jacketed fiber optic thread through a void space defined by a conduit of the fiber optic cable to the downhole tool to support optical telemetric communications between the downhole tool and surface equipment at the oilfield;
powerably coupling a plurality of coaxial, electrically conductive members adjacent the conduit of the fiber optic cable to the downhole tool to provide dedicated power thereto from the surface equipment, wherein the plurality of coaxial electrically conductive members are helically wound about the conduit and un-insulated relative to the conduit, wherein the fiber optic cable comprises an insulating polymer layer over the plurality of coaxial, electrically conductive members, a single metal based cladding layer extending circumferentially about the insulating polymer layer, and wherein the metal based cladding layer has a thickness such that the metal based cladding layer provides a durable shell for the insulating polymer layer;
advancing the downhole tool to the location with the coiled tubing; and
performing the coiled tubing application at the location.
