A cable separator includes a body, and the body includes a polycarbonate-based material that is at least a partially foamed. Cables and methods of manufacturing such cables having a separator are also provided.

Foamed polycarbonate separators and cables thereof

A communications cable having a plurality of twisted pairs of conductors and various embodiments of a metal foil tapes between the twisted pairs and a cable jacket is disclosed. In some embodiments, a metal foil tape includes a discontinuous metal layer and a polymer layer bonded to the metal layer. Portions of the metal layer and the polymer layer are deformed to form a plurality of dimples, the dimples forming air gaps between the polymer layer and the cable core or a barrier layer if used. The air gaps lower the overall dielectric constant between the metal layer and the cable core, thereby lowering the alien capacitance of the communications cable.

Communications cable with improved isolation between wire-pairs and metal foil tape

Twisted pair data communication cables with modified delay skew values to improve electrical performance are disclosed. Methods of making and using the cables are also disclosed.

Data communication cable having modified delay skew

A cable separator comprising a preshaped article having a longitudinal length, wherein said preshaped article is substantially entirely formed of a foamed polymer material having a glass transition temperature greater than 160&#xb0; C. and being halogen-free is provided. A data communications cable comprising a plurality of conductors and the cable separator of the present invention, wherein said cable separator separates the plurality of conductors is provided. A method of manufacturing a cable comprising the separator of the invention is also provided.

Foamed polymer separator for cabling

A cable includes a first twisted pair of insulated conductors, a second twisted pair of insulated conductors, a shielding tape, and an outer jacket surrounding the first twisted pair of insulated conductors, the second twisted pair of insulated conductors and the shielding tape. The shielding tape includes a substrate and a plurality of conductive shielding segments. The plurality of conductive shielding segments is disposed on the substrate. Each conductive shielding segment is spaced from each immediately adjacent conductive shielding segment in a longitudinal direction.

Cable having shielding tape with conductive shielding segments

A fire retardant composition is disclosed. The composition includes polyvinyl chloride, a plasticizer, a brominated fire retardant additive, a fire retardant synergist, and a metal stabilizer. Cable separators formed of the fire retardant composition are also disclosed.

Fire retardant compositions and cable separators formed thereof

A data cable can include a plurality of insulated conductors twisted into pairs, an intumescent tape surrounding one or more of the insulated conductors, and a jacket. Each of the plurality of insulated conductors includes a conductor and an insulation layer. Data cables being fluoropolymer-free or halogen free are also described herein.
