Norden Category 6A UTP cables exceed Category 6A / Class E specifications. It is tested to the 500 MHz frequency range and designed to support Gigabit 1000Base-T and 1000Base-Tx applications.Extremely high pair-balance providing excellent EMC (Electro Magnetic Compatibility), minimizing radiation, maximizing noise immunity, and providing high alien cross talk performance to UTP(Unshielded Twisted Pair) cabling systems. These external cables are constructed with steel tape armouring and are ideal for industrial use and in direct sunlight.
