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 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

The present invention relates to materials for making cable jackets, particularly for riser and plenum cables. The materials provide low flammability and allow the cable to meet UL 910 or NFPA-262 or UL 1666 specifications. The composition contains polyvinyl chloride (PVC) resin, a plasticizer, ammonium octamolybdate, a molybdate compound, a stabilizer, a lubricant, aluminum trihydrate, and either i) metal oxide particles, ii) a polytetrafluoroehtylene (PTFE), iii) an intumescent compound, or iv) combinations thereof.
