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).

Abstract: A container of the type known as a station wire box, from its application to dispensing wire for installation of telephone equipment on a user's premises, or station, is provided with an insert centrally located in one face of the box, for smooth manual dispensing of the wire, and perforations on the reverse side of the box. The perforations define a first area removable to form a combined access opening and carrying handle opening. The access opening allows access to ties binding a coil of wire, to remove the ties, and lead an end of the coil of wire through the insert. The reverse side also includes perforations defining areas adjoining the access opening which can be removed to form a circular opening in the box, equivalent in size to the circular opening in a conventional station wire box, so that the box can be used as a conventional station wire box.
