Cable with twisting filler

摘要

A cable includes an even number of pairs of conductors divided into an even number of groups and a single pair of conductors that encircle a length of filler material. The even number of groups conductors surround the single pair of conductors and the filler material. In one embodiment, the filler material is twined to cause an air gap to surround any portion of the groups that are not in contact with the filler material. In another embodiment, a longitudinal groove is formed on the outer surface of the filler material and the single pair of conductors rides on the groove. An outer shield surrounds all the pairs of conductors and the filler material. A method of forming the cable is disclosed.
