A communication cable includes at least a first and a second twisted pairs of conductors. The first twisted pair of conductors is covered by a first insulation material, and the second twisted pair of conductors is covered by a second insulation material that is different than the first insulation material. The second twisted pair of conductors has a signal phase delay that is substantially equal to the signal phase delay of the first twisted pair of conductors such that the skew of the cable is substantially zero. In certain embodiments, the first insulation material is a fluoropolymer. In such embodiments, the second insulation material may be a nonfluoropolymer. In addition, the twist lay of the first twisted pair of conductors may be different than the twist lay of the second twisted pair of conductors. Moreover, the thickness of the first insulation material may be different than the thickness of the second insulation material.

Signal phase delay controlled data cables having dissimilar insulation

An independent twin-foil shielded data cable is disclosed. The cable includes a cable core which may have one or more insulated data conductors. The cable core is wrapped by a foil-shield laminate tape color helically wound about the cable core. The laminate tape includes a non-conductive side facing the cable core and a conductive side facing outward from the cable core. A second-foil laminate shield tape is helically wound about the cable, having a conductive side disposed towards the conductive side of the first shield laminate and a non-conductive side disposed to the outside of the cable. Finally, the entire cable assembly may be enclosed in a protective, insulating jacket.
