ABSTRACT:
A communications cable having superior electrical characteristics and meeting the burn requirements for plenum applications has a core formed of one or more twisted wire pairs having primary insulation formed of a suitable material, such as high density polyethylene. The core is surrounded by a single outer jacket formed from a material having excellent heat/flame resistance characteristics and acceptable electrical characteristics that are substantially stable at relatively high temperatures, such as a foamed thermoplastic halogenated polymer, for example polyvinylidene fluoride material. The electrical conductors utilized by the cable are oversized (relative to conventional 24 gauge conductors) to enhance the electrical performance of the cable. An air gap formed between the conductor core and the outer jacket further enhances the electrical performance of the cable. In addition, the cable employs twisted pairs having specific twist lengths that enable the cable to exceed the electrical performance of conventional Category 5 cables.
