Concentric-eccentric high performance, multi-media communications cables and cable support-separators utilizing roll-up designs
First Claim
1. A high performance, multi-media communications cable, cable support-separator and/or jacket comprising;
- cable support members attached to and extending along an initially flat backing surface along a longitudinal length of said cable support-separator wherein said support members are separated by a gap, wherein said initially flat backing surface of said cable support-separator is flexible and may be rolled or folded thereby forming a central region, said central region extending along said longitudinal length of said communications cable and an outer shell or jacket;
said cable support members comprising radial and axial surfaces defined by shapes of essentially circular structures, said surfaces also including a gap wherein said gap allows for insertion and removal of conductive or non-conductive multi-media into and out of said essentially circular structures;
and wherein said initially flat backing surface once rolled or folded with or without said circular structures of said cable support-separator contain said conductive or non-conductive multi-media to form said high performance, multi-media communications cable.

Abstract
The present invention includes a high performance communications cable or cable support-separator and/or jacket that provides reduced cross-talk of any form between transmission media and includes one or more core support-separators having various shaped profiles which define a clearance to maintain spacing between transmission media or transmission media pairs. The core may be formed of a conductive or insulative material to further reduce cross-talk and improve other electrical properties as well as reduce flame and smoke spread. The cable and separators may be comprised of polymer blends that include olefin and/or fluoropolymer and/or chlorofluoropolymer based resins with and without inorganic additives such as nano-clay composites, C60 based compounds, etc. These unique blends offer both flame and smoke suppression while maintaining the characteristics necessary to improve electrical performance and allow for severe cost reduction compared with conventional separators. Alternatively, with no jacket for cable completion, a portion of the separator wherein a thin layer of material can act as a type of skin for future mechanical protection is provided. The specially shaped core support-separator has 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. In addition, the invention includes the optional incorporation of hollow ducts that can be used to provide for insertion of optical or metal conductor media either before, during, or after installation of the cable. In the case where insertion occurs after installation, the installation primarily utilizes gas driven means.
