  • Publication number: 20110048767
    Abstract: A multi-pair cable having a plurality of twisted conductor pairs and a tape arrangement. The tape arrangement providing a dielectric barrier between the twisted conductor pairs and a jacket of the multi-pair cable. The tape arrangement further defining at least two separate twisted pair regions in which the twisted conductor pairs lie.

  • Patent number: 6150612
    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).
