Abstract
Abstract A high-speed cable includes first and second coaxial conductor sets which are disposed in mirror image fashion within a carbon-impregnated polymer jacket. Each coaxial conductor set includes a wire core surrounded by a dielectric layer and a ground conductor disposed along side the dielectric layer. The wire core, the dielectric layer and the ground conductor are themselves surrounded by a conductive shield layer. In addition to assisting in bleeding off accumulated electric charge, the polymer jacket also preserves conductor set alignment and planarity especially following handling, cutting, trimming and stripping operations. The cable is excellent for high-speed applications, is easily routed and preserves its electrical properties under various field conditions.
