Solid Plenum Cat6 is designed to meet the strictest of electrical codes; our plenum cable meets or exceeds many common cable standards. The slow burn, low smoke jacket is comprised from CMP rated PVC. Four color-striped pairs make it easy to install and reduces alien crosstalk. Plenum cable is commonly used for structured cabling projects such as vertical, horizontal, or backbone systems. This bulk cable is in an easy-pull box and can be measured and cut to exact distances, then terminated to a connector, jack, or patch panel. Cat6 is certified for gigabit Ethernet. Features: Jacket Fire Retardant Polyvinyl Chloride (FR-PVC) 23 AWG Stranded Bare Copper Conductors Tested up to 550 MHz Meets Cat6 Standards RoHS Compliant ETL Listed CMP Rated "Plenum" refers to the highest fire-resistance standard of the National Electrical Code (NEC). Many local building codes specify that plenum-rated cables must be used in plenum air-return spaces, such as drop ceilings. These cables have special fire-retardant jackets, but there is no performance difference between plenum and non-plenum cables. Because plenum cables meet the highest standard, they can be used in any application, but due to price differences it makes sense only to use plenum cables when necessary.
