6452094, Sep 17, 2002

Filed:

Jun 3, 1999

Appl. No.:

09/325178

Inventors:

Daryle Pat Donner - Council Bluffs IA
Harold Wayne Friesen - Dunwoody GA
David R. Hawkins - Sugar Hill GA
Robert Henry Jackson - Grayson GA
Stephen Taylor Zerbs - Gretna NE

Assignee:

Lucent Technologies Inc. - Murray Hill NJ

International Classification:

H01B 1102

US Classification:

174 27, 174113 R

Abstract:

A local area network cable capable of high speed signal transmission has a plurality of twisted pairs of conductors enclosed within a jacket. Each of the twisted pairs has a different twist frequency than any of the other pairs, and at least one of the pairs has a direction of twist that is different from the other twisted pairs, that is, it may have a right hand twist where the other pairs have a left hand twist. In a four pair cable, two of the pairs, of different twist frequency, have imparted thereto a right hand twist, and two of the pairs have a left hand twist.

International Classification:

H01B 700

US Classification:

174110R, 174113 R, 174 27

Abstract:

A cabling media which is suitable for high performance data transmission includes a plurality of insulated metallic conductor-pairs, each pair including two plastic insulated metallic conductors which are twisted together. More specifically, the introduction of a periodic rotation along the length of each insulated conductor essentially acts to cancel out a large number of the adverse effects which may result due to a lack of conductor concentricity and/or dielectric eccentricity.

International Classification:

H04M 900

US Classification:

37941302, 37941303, 37941304

Abstract:

A system for cross-connecting network elements of different types through a common universal media. In the system, a media conversion interface is electrically connected to a network element. This media conversion interface passively maps the connector and cable type of the network element to a universal connector type. This media conversion interface is electrically connected to a cross-connect module in a universal distribution frame. This electrical connection uses a universal cable group and universal connectors. This cross-connect module is connected to another cross-connect module, also in a universal distribution frame, using a universal cable group and universal connectors. This second cross-connect module is electrically connected to a second media conversion interface, using a universal cable group and universal connectors. This second media conversion interface is electrically connected to a second network element, and passively maps the connector and cable type of the second network element to the universal connector.

Appl. No.:

11/012149

David Hawkins - Sugar Hill GA, US

Assignee:

General Cable Technology Corporation - Highland Heights KY

International Classification:

H01B 7/00

US Classification:

174113C

Abstract:

A cable includes a plurality of twisted pairs of insulated conductors, and an insulating cable jacket that has a central longitudinal axis encloses the twisted pairs of insulated conductors. The cable jacket defines an inner perimeter that surrounds the twisted pairs of insulated conductors that is substantially circular in section transverse to the central longitudinal axis and an outer perimeter that is substantially non-circular in section transverse to the central longitudinal axis. The outer perimeter includes at least one raised area for maintaining spacing from an adjacent cable, thereby reducing alien crosstalk.

International Classification:

H01B 11/02

US Classification:

174113R, 174117 F, 174117 FF, 174117 R, 174 27

Abstract:

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.

International Classification:

H01B 7/00

US Classification:

174113C

Abstract:

An electrical cable includes a cable jacket defining a central longitudinal axis and a plurality of twisted pairs of insulated conductors oriented longitudinally within the cable jacket. Each of the twisted pairs of insulated conductors has a width. A filler element is disposed in the cable jacket and is located adjacent to at least one of the twisted pairs of insulated conductors. The filler element defines a width that is substantially larger than the width of each the twisted pairs of insulated conductors. The filler element has a central axis laterally offset from the central longitudinal axis of the cable jacket. The filler element reduces alien crosstalk from an adjacent cable.
