Abstract

The present invention includes a high performance communications cable that provides for wireless fidelity applications and includes core support-separators having profiles which define a clearance to maintain spacing and/or channel between the transmission media and power conductors. The core may be formed of a conductive or insulative material that have, principally, polymer blends that include olefin and/or fluoropolymer and/or chlorofluoropolymer based resins. The polymer blends can also be utilized for fabricating shielding materials. The core support-separators have both a central region as well as a plurality of shaped sections that extend outward from the central region that are either solid or partially solid, foamed or foamed with a solid skin surface.

Claims

1. A high performance communications cable comprising at least one interior support, said support comprising a central region and outwardly extended portions extending from said central region, wherein said extended portions comprise conductive inorganic fillers and additives including shielding around individual conductors or conductor pairs and around said interior support such that said cable, interior support, central region and extended portions act alone or in synergy to lower or eliminate crosstalk between conductors, conductor pairs, and between complete cable constructions.

4. The high performance communications cable of claim 1, wherein said fillers and additives are metallic.

5. The high performance communications cable of claim 1, wherein said fillers and additives are semi-conductive.

7. The high performance communications cable of claim 1, wherein shielding of said cable is accomplished by metalizing any surface of said cable.

9. The high performance communications cable of claim 1, wherein shielding of said cable is accomplished by sputtering metal onto the surfaces of the insulation of said cable.

10. The high performance communications cable of claim 1, wherein shielding of said cable is accomplished by compounding conductive and/or semi-conductive nanocomposite fillers into the insulation of said cable.

11. The high performance communications cable of claim 1, wherein shielding of said conductors is accomplished by metalizing any surface of said conductors.

13. The high performance communications cable of claim 1, wherein shielding of said conductors is accomplished by sputtering metal onto the surfaces of the insulation of said conductors.

14. The high performance communications cable of claim 1, wherein shielding of said conductors is accomplished by compounding conductive and/or semi-conductive nanocomposite fillers into the insulation of said cable.

18. The high performance communications cable of claim 1, wherein said fillers and additives provide shielding around individual conductor pairs or around said interior support such that said cable and associated support, central region, and extended portions are capable of lowering or eliminating crosstalk and more specifically lowering alien near end crosstalk and/or far end crosstalk.

19. The high performance communications cable of claim 1, wherein said conductive fillers and additives are added to said extended portions, said extended portions including flap-tops which further serve as shielding for individual pairs of conductors and/or cables to reduce or eliminate alien near end cross talk or alien far end crosstalk between said conductors and/or cables and further minimizes disrupting communication signals from adjacent cables.

21. The high performance communications cable of claim 1, wherein said shielding is a belt-like shield that is formed into a round, smooth shape during manufacture and wherein said shielding is effective of shielding at least 1 GHz or higher frequency signal propagation.
