Publication number: 20100263907Abstract: 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.Type: ApplicationFiled: June 30, 2010Publication date: October 21, 2010Applicant: BELDEN TECHNOLOGIES, INC.Inventors: Gavriel Vexler, Galen Gareis

Patent number: 7772494Abstract: A telecommunications cable having a cable jacket defining an elongate cable core, a conductor assembly comprising four twisted pairs of conductors disposed along the core and parallel elongate distensions formed on an inner surface of the cable jacket. The distensions are spaced about an inner surface of the cable jacket and prevent the conductor assembly from coming into contact with the inner surface. The distensions can be 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. A separator spline has 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. The separator spline and the insulation surrounding the twisted pairs of conductors can be manufactured form a material having the same dielectric constant.Type: GrantFiled: March 6, 2007Date of Patent: August 10, 2010Assignee: Belden Technologies, Inc.Inventors: Gavriel Vexler, Galen Gareis

Patent number: 7276664Abstract: A dual layer shielded electrical cable is disclosed. The cable has at least a pair of insulated conductors, a metallic shield and a jacket surrounding the shield and insulated conductors. A first jacket layer made of flame retardant material surrounds the insulated conductors. A metallic shield then surrounds the first jacket layer. A second jacket layer then surrounds and seals the metallic shield against the first jacket layer, such that the insertion of the first jacket layer provides the cable with electrical signal attenuation and impedance characteristics equivalent to that of an unshielded cable with similar conductor insulation thicknesses. In another embodiment, a dual layer plenum rated electrical cable is disclosed. The cable has at least a pair of insulated conductors and a jacket surrounding the insulated conductors. Both the first and second jacket layer are made of a low-smoke and flame-retardant materials.Type: GrantFiled: July 1, 2002Date of Patent: October 2, 2007Assignee: Belden Technologies, Inc.Inventor: Gilles Gagnon
