Our white plenum shielded solid Cat6a Ethernet cable is used for networking and phone infrastructure and comes in a convenient spool. Cat6a Cable is used in network applications and has been designed specifically for 10 Gigabit Ethernet applications. This particular cable is a plenum rated white shielded bulk cable. The individual conductors are 23 AWG (American wire gauge) solid pure copper. Our Cat6a Ethernet cable exceeds the EIA/TIA-568-C standard. In a typical residential environment, an in-wall rated cable will suffice. However, commercial installations of cabling will have more requirements. In commercial 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 jacketed with a fire-retardant plastic jacket of either a low-smoke polyvinyl chloride (PVC) or a fluorinated ethylene polymer (FEP) for less toxicity during a fire. If a fire gets into a plenum rated area that contains plenum rated cables and the fire spreads, the cables will not be to blame.
