Abstract: A high speed data transmission cable includes a plurality of primary cables, wherein each primary cable includes a pair of generally parallel, insulated conductors, and has opposing short sides and opposing long sides. A shield layer surrounds each primary cable along its length to individually electrically isolate the primary cables from each other. The plurality of primary cables are positioned around a cable center axis with finite numbers of primary cables arranged side-by-side with each other to define distinct orbitals around the center axis. The primary cables of the orbitals have a respective long side generally facing radially inwardly toward the center axis. The primary cables of the orbitals are wrapped generally helically around the center axis along the length of the cable without each primary cable conductor pair being significantly individually twisted about each other along the cable length.

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.

Abstract: A high speed data transmission cable comprises a pair of primary cables positioned adjacent to each other along their lengths with each primary cable including a pair of generally parallel conductors coupled together and surrounded by insulation. 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, thereby providing improved transmission characteristics in the high speed data transmission cable.
