Jeffrey H. Mumm - Marietta GA, US
Christopher W. McNutt - Woodstock GA, US
Jeffrey Scott Laws - Brownwood TX, US

Assignee:

Superior Essex Communications LP - Atlanta GA

International Classification:

G02B006/44

US Classification:

385100

Abstract:

A communication cable for transmitting various communication signals. The cable comprises buffer tubes for optical fiber cables that are robust, crush resistant, flexible, and cost effective. To obtain these properties, the buffer tubes contain a polymeric mixture of high impact polystyrene and styrene-butadiene-styrene. The polymeric mixture for the buffer tubes may also contain crystalline polystyrene and/or acrylonitrile-butadiene-styrene.

Appl. No.:

10/659139

Inventors:

Christopher W. McNutt - Woodstock GA, US
Jeffrey H. Mumm - Marietta GA, US

Assignee:

Essex Group, Inc. - Ft. Wayne IN

International Classification:

G02B 6/44

US Classification:

385100

Abstract:

A buffer tube for use in a fiber optic cable is disclosed. The buffer tube has a flexural modulus greater than about 180 kpsi and less than about 370 kpsi, which results in a buffer tube having good crush resistance and flexibility. A particularly useful buffer tube material is an alloy of polypropylene and polyphenylene oxide, which may contain solid fillers.

Assignee:

Superior Essex Communications, LP - Atlanta GA

International Classification:

H01B 11/02

US Classification:

174113R

Abstract:

A communications cable having increased fire resistance and reduced attenuation and crosstalk includes a core having at least one insulated electrical conductor, and a jacket having an inner surface and a plurality of ribs projecting radially inward from the inner surface, the ribs separated from one another by adjacent channels that extend longitudinally along the length of the cable.

Inventors:

James J. Puzan - Canton GA, US
Christopher W. McNutt - Woodstock GA, US
Jeffrey S. Laws - Brownwood TX, US

Assignee:

Superior Essex Communications LP - Atlanta GA

International Classification:

G02B 6/44

US Classification:

385109

Abstract:

A fiber optic cable can inhibit water, that may inadvertently enter the cable, from damaging the cable's optical fibers. The fiber optic cable can comprise a buffer tube defining an interior volume extending along the fiber optic cable. Optical fibers can be disposed in the interior volume of the buffer tube, along with water-swellable materials, such as tapes and yarns. The interior volume can be dry or free from water-blocking gels or fluids. The water-swellable materials can provide the fiber optic cable with an unexpected level of protection from seawater. The water-swellable materials can, for example, limit flow of seawater along the interior volume. In an exemplary embodiment, progression of seawater in the interior volume be limited to three meters or less for a twenty four hour test period during which the seawater is under about one meter of head pressure.

Appl. No.:

12/313910

Inventors:

Delton C. Smith - Kennesaw GA, US
James S. Tyler - Woodstock GA, US
Christopher McNutt - Woodstock GA, US

Assignee:

Superior Essex Communications LP - Atlanta GA

International Classification:

H01B 11/06

US Classification:

174 36, 174112

Abstract:

A tape can comprise a dielectric film that has a pattern of electrically conductive areas adhering thereto. The conductive areas can be electrically isolated from one another. The tape can utilize means to obscure the metallic finish and can contain indicators to deter installers from grounding the tape at either end. The tape can be wrapped around one or more conductors, such as wires that transmit data, to provide electrical or electromagnetic shielding for the conductors. The resulting cable can have a shield that is electrically discontinuous between opposite ends of the cable.

Assignee:

Superior Essex Communications LLP - Atlanta GA

International Classification:

H01B 11/02

US Classification:

174113R, 174 36

Abstract:

A tape can comprise a two-sided strip of dielectric material, with patches of electrical conductive material adhering to each side. Patches on one side can be longitudinally offset from patches on the opposite side. The patches can be electrically isolated from one another. The tape can be wrapped around one or more conductors, such as wires that transmit data, to provide electrical or electromagnetic shielding. The patches can circumferentially encase the conductors, with patches on one side of the tape covering gaps on the other side of the tape. The tape can be wrapped around the conductors so that an edge of a patch spirals about the conductors in a rotational direction opposite to any twisting of the conductors. The resulting cable can have a shield that is electrically discontinuous between opposite ends of the cable.
