In addition to the mechanical stresses caused by wind, icing, etc., the manufacturer of an optical aerial cable has to consider the electrical stress mechanisms (corona discharge, &ldquo;tracking&rdquo; effect) which lead to premature aging of the outer jacket by considering constructive measures and the use of special jacket materials. The outer jacket of the aerial cable contains several PE fusible fibers embedded into the jacketing material, whose conductivity is based on the content of carbon black in the amount of 10% of weight to 40% of weight. The resistance of these fusible fibers manufactured by coextrusion with the outer jacket is sufficiently low at 10 &OHgr;/m-10 &OHgr;/m, to discharge the induced electrical charges to the anchoring spirals fastened to the pole. No large potential differences in the longitudinal direction of the cable can occur on the wet, only partially dried jacket surface.

In order to reduce the polarization-mode dispersion, disturbance mechanisms are provided along the length of the respective optical waveguide in a statistically distributed manner. The disturbance mechanisms bring about additional polarization-mode couplings for transmission light in the optical waveguide interior.
