Abstract:
1. A cable comprising: a plurality of twisted pairs of insulated conductors including a first twisted pair and a second twisted pair, each twisted pair comprising two insulated conductors twisted together in a helical manner; a separator disposed among the plurality of twisted pairs of insulated conductors so as to physically separate the first twisted pair from the second twisted pair; and a jacket surrounding the plurality of twisted pairs of insulated conductors and the separator; wherein the jacket comprises a plurality of protrusions extending away from an inner circumferential surface of the jacket; wherein the plurality of protrusions cause the plurality of twisted pairs of insulated conductors to be kept away from the inner circumferential surface of the jacket along an entire length of the cable; and wherein the jacket is shaped such that, between each two protrusions of the plurality of protrusions, the inner circumferential surface of the jacket has an arc shape.
