Abstract
A communications cable that may be used in buildings in concealed areas such as riser shafts is constructed of non-halogen materials. The core includes insulated conductors that are enclosed with a plastic, polyolefin insulating material. These insulated conductors are twisted into pairs to form a multi-pair core. The core is surrounded and protected with a non-halogen, plastic jacket material. The cable has exceptional voice and data transmission properties due to the polyolefin insulation and is highly flame retardant. Compared with halogenated materials, the cable generates relatively little smoke, is less corrosive, and generates less toxic gases when burned.
