ABSTRACT:
A cable includes a jacket surrounding first and second insulated conductors and a first dielectric tape, wherein the first insulated conductor is twisted with the second insulated conductor with the first dielectric tape residing therebetween to form a first twisted pair. The cable's jacket may also surround a similarly formed second twisted pair. In alternative or supplemental embodiments of the invention, the first insulated conductor includes a first conductor surrounded by a layer of first dielectric insulating material having a radial thickness of about 7 mils or less; the first dielectric tape has a first width which is equal to or less than the diameters of the first and second insulated conductors plus a thickness of the first dielectric tape; the first dielectric tape has a cross sectional shape, which presents first and second recessed portions for seating the first and second insulated conductors; twist lengths of the first and second twisted pairs are between approximately 0.22 to 0.38 inches and different from each other; the first dielectric tape is different in shape, size or material content as compared to a second dielectric tape of the second twisted pair; the insulated conductors of the first and second twisted pairs are identical in appearance, while the first and second dielectric tapes are different in appearance; and/or the first dielectric tape has a hollow core possessing a gas or material with a lower dielectric constant.
