A cable includes a jacket, a shielding tape, a pair of wires, an inner and outer jacket layer, and a separator. The shielding tape includes a substrate and a plurality of conductive shield segments disposed on the substrate. The pair of wires form a twisted pair. The inner and outer jacket layers are extruded onto inner and outer surfaces, respectively, of the substrate. The substrate, the inner jacket layer and the outer jacket layer are bonded together into a single layer that defines a circumference. Each of the conductive shield segments: extends only partially around the circumference of the single layer; is longitudinally spaced from each longitudinally adjacent one of the conductive shield segments; is radially spaced from, and overlaps a portion of, each immediately circumferentially adjacent one of the conductive shield segments; and is embedded in at least one of the inner jacket layer and the outer jacket layer.

Method for making cable jacket with embedded shield

A method for making a cable jacket that includes the steps of providing at least one shielding tape having a substrate formed of a substrate material, said substrate including at least one conductive segment; inserting the at least one shielding tape between first and second jacket layers of the cable jacket, each of said first and second jacket layers being formed of a jacket material; and co-extruding the at least one shielding tape with the first and second jacket layers, wherein the substrate material of the at least one shielding tape and the jacket material of the first and second jacket layers are the same such that during the co-extrusion step, the substrate and first and second jacket layers bond together into a single layer wherein the at least one conductive segment is embedded in the single layer.

The present invention relates generally to cables suitable for use in plenum applications. In particular, the present invention relates to coaxial cables suitable for use in plenum applications (which exhibit flame spread and smoke generation properties that comply with industry standards, e.g., UL 910 or NFPA 262) without compromising electrical performance. The cable has two or more layers of insulation where the inner layer is made of a material having a high melt flow index and the outer layer is made of a material having a low melt flow index.

Communication cable

A data communications cable is disclosed herein. The data communications cable includes a plurality of twisted pairs of conductive wires and a separator between the plurality of twisted pairs of conductive wires. The separator includes an inner member and an outer layer being supported and shaped by the inner member for completely encapsulating at least one gas pocket between the outer layer and the inner member. The outer layer prevents the plurality of twisted pairs of conductive wires from entering the at least one gas pocket.

Gas encapsulated dual layer separator for a data communications cable

A cable component that comprises a main body where at least a part of the main body is formed of an insulation material, and at least one non-flammable portion is disposed in the insulation material of the main body. The non-flammable portion forms at least about 25% by volume of the cable component, is flexible, and reduces the amount of the insulation material of the main body, thereby reducing the fuel load in the cable component.

Cable component with non-flammable material

Embodiments of the present invention relate to methods and apparatuses directed towards communication cables and barrier tapes for use in communication cables. In an embodiment, the present invention employs conductive segments within the communication cables and/or on the barrier tape.

Communication cable with improved crosstalk attenuation

A cable that has a cable core which includes a plurality of pairs of insulated conductors, a barrier layer surrounding at least one pair of the insulated conductors, and at least one shielding layer that is provided between the plurality of pairs of insulated conductors. The barrier layer may be non-conductive and the shielding layer may be conductive.

Cable with barrier layer

A cable that has a cable core that includes at least one conductor that is surrounded by insulation. A barrier layer substantially surrounds the conductor's insulation. The barrier layer may include a plurality of shielding segments. Each of the shielding segments extends substantially around a circumference of the barrier layer. The shielding segments may be spaced from one other to form a discontinuous shield around the conductor.

Cable barrier layer with shielding segments

A matrix tape with conductive segments. The conductive segments are preferably provided on two layers of the matrix tape. The conductive segments can be attached to a film with an adhesive. A barrier tape is preferably applied between the cable core and the matrix tape.

A communication cable that comprises a jacket, a twisted wire group, and a single separator received in a core of the jacket. The separator includes a body that has first and second segments adapted to define quadrants in the communication cable. The first and second segments are substantially perpendicular to each other and define a junction point of the first and second segments. Each segment includes a main portion and a terminal end remote from the junction point of the segments. Each of the terminal ends has a shape such that each of the terminal ends is wider than the main portions of the segments. An air pocket is defined between the terminal ends of the first and second segments. The air pocket includes a gap sized such that the air pocket is substantially enclosed, wherein the twisted wire group is prevented from entering the air pocket.

Separator for communication cable with shaped ends

Methods and apparatus directed towards communication cables and barrier tapes for use in communication cables are disclosed herein. In an embodiment, the present invention employs conductive segments within the communication cables and/or on the barrier tape.

A barrier tape used as part of a communication cable has one or more barrier layers of discontinuous conductive segments. Conductive segments of one barrier layer are preferably sized and shaped to overlie gaps between conductive segments of another barrier layer.
