Patent number: 8263201Abstract: A self-laminating rotating cable marker label is constructed of a transparent film having a first adhesive area, an adhesive-free smooth area, and a second adhesive area. A print-on area forms one side of the transparent film, the print-on area adapted to receive indicia identifying the cable about which the marker label is applied. A perforation extends across the transparent film providing a line of separation of the transparent film. When wrapped around a cable, the second adhesive area overlies the print-on area such that the cable identifying indicia is visible through the transparent second adhesive area. As the transparent film is wrapped around the cable, the first adhesive area adheres to the cable. The remainder of the transparent film is rotated, breaking the perforation, whereby the smooth area of the film in contact with the cable provides smooth rotation of the label around the cable.Type: GrantFiled: May 7, 2009Date of Patent: September 11, 2012Assignee: Panduit Corp.Inventors: Jack E.

Patent number: 8253023Abstract: Communication cables are provided in which a core lay length of the cable varies along the cable length. The cable may be provided with different segments that have different core lay lengths. It is desirable for neighboring core lay lengths in a cable to differ by a factor of two, to enable a reduction in power-sum alien near-end crosstalk (PSANEXT) when two cables are installed alongside one another. Segments of the cable having different core lay lengths may be spaced periodically along the length of the cable, and the periodicity of the spacing may be altered by a jitter distance. The introduction of jitter into the periodicity of the spacing of the segments increases the likelihood that a beneficial placement of core lay lengths will occur when two or more cables are installed alongside one another.Type: GrantFiled: January 13, 2010Date of Patent: August 28, 2012Assignee: Panduit Corp.Inventors: Masud Bolouri-Saransar, Michael V. Doorhy, David R. Hawkins, Asef Nimer Baddar, Thomas Gerard McLaughlin

Patent number: 8217268Abstract: Systems and methods for decreasing alien crosstalk use enhanced patch cords for introducing additional attenuation. The enhanced patch cords are preferably shielded to reduce alien crosstalk down their lengths and also attenuate signals passing therethrough to a greater extent than standard communication patch cords. The interaction of two enhanced patch cords results in two suppression steps for alien crosstalk and only one suppression step for intended signal passing through a communication cable.Type: GrantFiled: May 27, 2010Date of Patent: July 10, 2012Assignee: Panduit Corp.Inventors: Ronald A Nordin, David R Hawkins, Michael V.
