Abstract
The present invention includes a high performance communications cable exhibiting reduced cross-talk of any form between transmission media that includes one or more core support-separators having various shaped profiles which define a clearance to maintain a 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 are comprised of principally polymer blends that include olefin and/or fluoropolymer and/or chlorofluoropolymer based resins with and without inorganic additive such as nano-clay composites. These unique blends offer both flame and smoke suppression while maintaining the characteristics necessary to improve electrical performance and allow for severe cost reduction over conventional separators. The specially shaped core support-separators can be either interior to the cable jacket or be employed singularly without the benefit of a jacket and extend along the longitudinal length of the communications cable. Alternatively, with no jacket for cable completion, a portion of…
