Abstract
A high speed data transmission cable having a pair of primary cables positioned adjacent to each other along their lengths, with each primary cable including a pair of generally parallel conductors which are coupled together by an insulation structure. The insulation structure has a cross-section including shaped end portions wherein each end portion is defined by a reference point. The conductors are positioned proximate the reference points of the circular end portions. The shaped end portions are coupled together by a center portion to form the insulation structure having dimensions reflective of the dimensions of the end portions. A shield layer surrounds each primary cable along its length to isolate the primary cables from each other. The primary cables and corresponding shield layers are twisted together around a center axis and form a double helical structure.
