Abstract
The cable has optical fibers embedded in a material filling the tube which itself lies inside a helical lay of metal wires having high mechanical strength and in which the interstices are filled with a sealing material. The cable includes a first extruded sheath between the tube and the helical lay, and the helical lay is itself covered by a second extruded sheath which is insulating and abrasion resistant, and if the cable is for a remotely-powered link, it includes a conductive strip on the tube or on the first sheath.
