Abstract: A cable includes a pre-selected number of binder units. Each binder unit includes an even number of paired couples of conductors, evenly divided into quads, and an additional twisted pair of conductors, coupled with and encircled around a length of a filler material, extended in parallel so the quads of conductor pairs surround the additional pair of conductors and the filler material. A binder unit wrap encloses each binder unit and a foil free edge tape is applied with the foil facing inwardly and a drain wire pulled between the foil and the unit wrap. An overall core wrap encloses each binder unit, and a shield is applied over the top of the overall core wrap such that the shield surface faces inwardly for improved termination methods. An overall drain wire is placed between the overall core wrap and overall shield. The entire cable may be enclosed by a jacket or sheath. A method for forming the cable is also disclosed.

Abstract: High performance data cables are provided that allows for future growth in networking speeds. The high performance data cables achieve this result while satisfying the dimensional requirements set by the EIA/TIA 568-A standards as well as fire performance safety requirements of the National Fire Protection Association (NFPA). High performance data cables of this invention achieve the above by controlling parameters that influence impedance performance, near-end crosstalk performance and attenuation. A separating filler material is used to maximize the pair-to-pair distance while maintaining an overall maximum outside diameter of 0.250". This construction benefits crosstalk performance, as both electrical and magnetic field intensities are inversely related to distance and dielectric constant (crosstalk is made up of capacitative and inductive coupling, with inductive coupling becoming significant at frequencies above 50 MHz).
