"Fiber optic cable, and combined system for transporting electric energy of high voltage and optical communications.A fiber optic cable having high resistance to the formation of tracks, comprising at least one optical fiber (6), and an outer sheath of double layer extruded polymer based (4),Comprising a first polymer layer (4a) substantially without resistance to the formation of trails.And a second outer polymer layer (4b) having the characteristics of high resistance to the formation of trails.Obtained preferably by adding a predetermined quantity of an inorganic oxide, hydroxide or hydrated form and, preferably, to the polymer matrix.In this way, it is possible to produce a fiber optic cable, which has high resistance to the formation of trails, it is lightweight, has a high mechanical strength.And is particularly suitable for installation along the overhead lines of high voltage.
