Cat6 Shielded F/UTP cables meet TIA/EIA 568-C.2 Category 6 and ISO/IEC 11801 Ed2 Class E standards. SCP Cat6 Shielded F/UTP cables are recommended in environments with potential EMI or RF interference. The SCP Cat6 Shielded F/UTP cables are UL and Riser Rated. Each Cat6 Shielded F/UTP cable is 550 MHz 23 AWG insulated solid bare copper conductors with a center spline separating the pairs. It is shielded with an overall AL foil shield providing superior noise resistance. This creates a round and flexible cable for easy pulling and stripping of the cable jacket. These cables are packaged on 1000ft/305 meter wooden spool/drum.
