Patent ID: 7358436

Claim:
A data cable comprising: at least one twisted pair unit including a first insulated conductor surrounded along its length by a first insulating layer and a second insulated conductor surrounded along its length by a second insulating layer; and a jacket surrounding the at least one twisted pair; wherein the at least one twisted pair further comprises a third insulating layer surrounding the first insulated conductor and the second insulated conductor along their lengths to comprise first and second dual-insulated conductors, the third insulation also fixing the first first insulated conductor to the second dual insulated conductor along their length; wherein a distance between a center of the first insulated conductor and a center of the second insulated conductor is less than a sum of a distance from the center of the first insulated conductor to a proximate edge of the third insulating layer and a distance from the center of the second insulated conductor to an opposing edge of the third insulating layer, measured along a reference line that passes through the centers of the first and second insulating conductors wherein the third insulating layer is formed such that the twisted pair has a flat oval shape; and wherein the first and second insulated conductors and the third insulating layer are twisted about a common central axis to form the at least one twisted pair.
