A telecommunications cable includes multiple binder units. Each binder unit includes a predetermined number of twisted pairs enclosed by a binder unit wrap. A foil free edge tape is applied over the top of the unit wrap with the foil facing inwardly. A drain wire is pulled between the foil and the unit wrap. A preselected number of binder units are enclosed by an overall core wrap, 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 and overall shield. The entire cable may be enclosed by a jacket or sheath.

A method of forming flexible communications wire for use in Local Area Networks is disclosed. A plurality of individual metal strands are formed into a central conductor. The central conductor is then compressed and/or heated to bond adjacent strands together and to reduce the diameter of the wire.

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). Balancing between parameters that influence impedance, near-end crosstalk and attenuation performance by choice of materials and physical dimensions of the filler material, insulation material, jacket material and conductor, the overall performance of the data cable of this invention is achieved. A standard for the high performance data cables of this invention is also disclosed.
