ABSTRACT:
Disclosed is a cable in which one tube holding light waveguides is connected by a plastic web to another tube holding metallic current carrying conductors. When buried in the earth, the cable may be located by means of a magnetic field produced by the current carrying conductors, but the cable retains the advantage of the tube carrying the light waveguides being dielectric.
