Norden Category 6 SF/UTP cables exceed Category 6/ Class E specifications. It is tested to a 250 MHz frequency range and designed to support Gigabit 1000Base-T and 1000Base-Tx applications up to 100m. Extremely high pair balance provides excellent EMC (Electro Magnetic Compatibility), minimizing radiation. maximizing noise immunity, and providing high alien cross-talk performance to cabling systems. SF/UTP (Overall shield and Foil) cabling systems are installed for improved Alien Crosstalk performance.
