Abstract: A cable may include a plurality of twisted pairs of individually insulating electrical conductors, and a respective individual shield formed around each of the twisted pairs. Additionally, each individual shield may include electrically conductive material that is continuous in a longitudinal direction. An overall shield may be formed around the plurality of twisted pairs and individual shields. The overall shield may include a dielectric layer, a first layer of electrically conductive material that is continuous in the longitudinal direction formed on a first surface of the dielectric layer, and a second layer of electrically conductive material that is continuous in the longitudinal direction formed on a second surface of the dielectric layer opposite the first surface. The first and second layers of electrically conductive material and each of the individual shields may be in electrical contact with one another. Additionally, a jacket may be formed around the overall shield.

Abstract: A communication cable can comprise twisted pairs of electrical conductors for transmitting electrical signals, such as for digital communication or data transmission. The pairs can be twisted to different tightness in connection with managing interference among the pairs. Within the cable, a separator having an economical polymeric composition can maintain the pairs in a desired orientation. The pairs can be insulated with polymeric materials that compensate for relaxed electrical characteristics of the economical polymeric composition of the separator. One or more pairs having relatively tight twist can be insulated with a premium polymeric material that provides a relatively high level of electrical performance. One or more pairs twisted less tightly can be insulated with another polymeric material providing somewhat lesser but still sufficient electrical performance.

Abstract: A communication cable can comprise twisted pairs of electrical conductors for transmitting electrical signals, such as for digital communication or data transmission. One or more electrical conductors of the cable can be insulated with a premium polymeric material that provides relatively high levels of electrical performance and fire performance. For example, one or more of the electrical conductors could be insulated with fluorinated ethylene propylene. One or more other electrical conductors of the cable can be insulated with other, economical polymeric materials in a configuration meeting electrical and fire performance objectives. For example, one or more of the electrical conductors could be insulated with foamed polyolefin, such as foamed polyethylene, covered by a polyvinyl chloride skin that functions as a fire barrier.

Abstract: An axially arranged cable, such as a coaxial, triaxial, twinaxial, or armored cable which includes at least one serration on an insulative or conductive layer internal thereto and methods of manufacturing the same. These serrations may appear on insulators or inner jackets and are in physical contact with conductive layers such as shields which axially surround the insulative layers. The serrations generally increase the contact force between the insulative layers and the conductiver layers to help prevent separation of the cable core during stripping of the axial cable.

Abstract: A flexible shielded cable that employs a thin metallic foil or plastic metallic foil tape having a metal surface wherein the metallic foil or metal surface is less than 0.0030 inches in thickness disposed about a layer of dielectric material and disposed within a metallic serve or braid. The thin metallic foil prevents or reduces relative movement of the dielectric and the conductor core disposed therein relative to the braid. Preferably, either the metallic foil or braid is a noncopper metal.
