Abstract
A high performance controlled impedance low loss low attenuation cable having the characteristics of a shielded twisted pair cable is disclosed. The cable contains a plurality of pairs of associated conductors located in a single plane to give a low profile flat cable suitable for use in undercarpet wiring installations. The cable comprises a plurality of layers of extruded insulating material with a metal foil shield surrounding only associated pairs of conductors. Insulating material having different dielectric constants is employed in conjunction with the encircling foil shield to give the cable the characteristics of a conventional shielded twisted pair cable.
