ABSTRACT:
A novel flat-wire-pair and cable architecture are disclosed. The invention implements flattened conducting wires coated with insulation that are bonded to each other, providing approximately rectangular cross-sections and flat surfaces for the transport of charge through the wires. Flat wire pairs are then placed within a cable assembly such that adjacent wire pairs are oriented orthogonally or in other such manner adjacent to each other to minimize crosstalk and render crosstalk common-mode. Flat wire pairs are also shielded for additional cross-talk minimization as well as near-field EMI minimization. A cable consisting of multiple flat wire pairs may also be shielded in its external jacket that maintains cable structure, and may include additional conductors for reference and static signals. Through these enhancements, the invention cable architecture eliminates intra-pair and inter-pair skew while substantially reducing signal loss due to skin-effect as well as rendering crosstalk harmless. Shielded flat wire pair cables are thus ideally suited to very high-speed data communication over significant distances.
