Plenum-rated cable is made specifically for commercial installations. In buildings, there will be an area between floors or above office areas for heating/cooling airflow called the Plenum. If an office were to catch fire, this plenum area could easily allow the spread of the fire to more floors or across the entire building. Cables that do not have a jacket rated for in-wall or plenum use could actually cause the fire to become more intense. Plenum rated cables are covered with a fire-retardant plastic jacket of either a low-smoke polyvinyl chloride (PVC) or a fluorinated ethylene polymer (FEP) which expels less toxins during a fire. Plenum rated cables can help prevent the spread of fires, but keep in mind that a Plenum rated cable will have no data transmission speed benefit over a non-Plenum rated cable. Color is red.
