Abstract
Abstract A low cost high signal frequency multiwire cable and method of manufacture includes a stack of wire pairs fan folded from a flat ribbon cable to form columnated wire pair layers. The flat ribbon cable is folded together with a flexible conductive shield which extends around and between each layer to provide high quality signal isolation of each layer. The cable may be clad with multiple layers providing additional shielding and physical protection.
