Cavo aereo in fibra ottica

It is disclosed an aerial fiber optic cable comprising a fiber unit, one or more strength members and a polymeric sheath. The optical fiber unit comprises a number of optical fibers, an inner layer, which is radially outer to the optical fibers and embeds the optical fibers, and an outer layer which is radially outer to the inner layer, the outer layer comprising particulate material which is partially embedded into the outer layer. The one or more strength members are arranged in a radial outer position with respect to said optical fiber unit and the sheath is extruded over the optical fiber unit and the one or more strength members.
