Data cable with cross-twist cabled core profile

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 provide an air gap between the plurality of twisted pairs of insulated conductors and the inner circumferential surface of the jacket along an entire length of the cable;
• and
• wherein a boundary of the air gap adjacent the inner circumferential surface of the jacket is arc shaped.

• 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 toward a center of the cable, the plurality of protrusions being configured so as to keep the plurality of twisted pairs away from the inner circumferential surface of the jacket along an entire length of the cable, thereby reducing susceptibility of the plurality of twisted pairs to alien near end crosstalk;
• and
• wherein, between each two protrusions of the plurality of protrusions, the inner circumferential surface of the jacket is arc shaped.
