What is Polyvinyl Chloride (PVC) cabling?

A grade of network cabling that uses polyvinyl chloride (PVC) plastic for its outer protective insulating jacket. Polyvinyl chloride cabling is cheap and flexible but gives off dangerous gases during combustion. Building codes usually require that plenum cabling be used instead of polyvinyl chloride cabling for horizontal runs from wiring closets to wall plates.

Polyvinyl chloride cabling is usually used to connect wall plates to computers. Both coaxial and twisted-pair cabling are generally available in either polyvinyl chloride or plenum-grade jackets.
