20100263907WEB FOR SEPARATING CONDUCTORS IN A COMMUNICATION CABLE - A telecommunications cable and separator spline. In one example the cable includes a cable jacket defining an elongate cable core, a conductor assembly including four twisted pairs of conductors disposed along the core and a plurality of parallel elongate localized and like distensions in an inner surface of the cable jacket. The distensions are substantially evenly spaced about an inner surface of the cable jacket and prevent the conductor assembly from coming into contact with the inner surface. In one example, the distensions are the result of a series of filler elements placed between the cable jacket and the cable core and which wind helicoidally along and about the cable core. The separator spline is comprised of first and second elongate dividing strips having a substantially H shaped cross section and arranged side by side. The spline twists helicoidally along its length. In one example the separator spline and the insulation surrounding the twisted pairs of conductors is manufactured form a material having the same dielectric constant.10-21-2010

20080314614MIRRORED ARC CONDUCTING PAIR - A mirrored arc geometrical arrangement of two conductors configured to perform similar functions as a traditional twisted pair of wires is presented. The mirrored arc conductor pair occupies the same physical space required by prior art twisted pair cable designs. Each conductor pair includes two inward-facing arc shaped conductors placed within a dielectric material. Each arc shaped conductor may be constructed from thin foil strips of a conducting metal or from a group of separate bare metal conductors which are placed side by side in intimate contact so as to effectively create the same mirrored arc geometry. The conductor pairs may subsequently be bundled to create a data network cable bundle.12-25-2008
20080264670High performance support-separators for communications cables supporting low voltage and wireless fidelity applications and providing shielding for minimizing alien crosstalk - 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.10-30-2008
20100243291HIGH PERFORMANCE COMMUNICATIONS CABLES SUPPORTING LOW VOLTAGE AND WIRELESS FIDELITY APPLICATIONS PROVIDING REDUCED SMOKE AND FLAME SPREAD - The present invention provides conductive and/or insulative compositions comprising polymer blends that include olefin and/or fluoropolymer and/or chlorofluoropolymer based resins with and without inorganic additives. These compositions reduce flammability and smoke generation and are used primarily for insulation materials and for high performance communications cables. In addition, support-separators using these same compositions, to be used within the communications cables, and normally within the cable core, are described. These unique compositions include polymer blends that offer both flame and smoke suppression while maintaining the characteristics necessary to improve electrical performance and allow for severe cost reduction over conventional separators. These polymers blends can also be utilized for fabricating shielding materials. 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, if no jacket is used for cable completion, a portion of the separator with a thin layer of material surrounding the separator core can act as a type of skin for mechanical protection. Specially shaped core support-separators have both a central region as well as a plurality of shaped sections that extend outward from the central region for which the materials of construction are either solid or partially solid, foamed or foamed with a solid skin surface.09-30-2010
