Abstract: A cable includes a jacket, a shielding tape, a pair of wires, an inner and outer jacket layer, and a separator. The shielding tape includes a substrate and a plurality of conductive shield segments disposed on the substrate. The pair of wires form a twisted pair. The inner and outer jacket layers are extruded onto inner and outer surfaces, respectively, of the substrate. The substrate, the inner jacket layer and the outer jacket layer are bonded together into a single layer that defines a circumference. Each of the conductive shield segments: extends only partially around the circumference of the single layer; is longitudinally spaced from each longitudinally adjacent one of the conductive shield segments; is radially spaced from, and overlaps a portion of, each immediately circumferentially adjacent one of the conductive shield segments; and is embedded in at least one of the inner jacket layer and the outer jacket layer.
