Abstract
A cable which comprises a plurality of pairs of first and second insulated conductors. The first and the second insulated conductors, of each pair, are twisted with one another to form a twisted pair and each of the twisted pairs has a different lay length from one another. Each of the plurality of twisted pairs is wrapped with a hoop strength wrap which maintains a mechanical strength and integrity of the twisted pair during subsequent handing thereof, and a circumference of the hoop strength wrap is about 5% or less than a dielectric pair minimum circumference of the first and the second insulated conductors of the twisted pair. At least one metallic wrap is provided for shielding and grounding of the plurality of twisted pairs. The plurality of twisted pairs and the at least one metallic tape are surrounded and encased by a conventional exterior jacket to form the cable.
