摘要: 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.

摘要: Disclosed is a dielectric cable having two tubes separated by a web, one tube holding at least one light waveguide therein and the other tube holding a material which creates a magnetic field capable of above ground detection when the cable is buried.

摘要: A light waveguide cable includes a compartment holding at least two side-by-side stacks of light waveguide ribbons. The cable is so dimensioned that the order of the ribbons within any stack, and the relative positions of the stacks with respect to each other within any compartment, do not change under normal cable handling conditions.
