Excel Category 6 Unscreened Twisted Pair (UTP) Twin LSOH cables are manufactured and tested to the TIA/EIA 568-B.2-1, EN50173-1 and ISO/IEC 11801 Category 6 specifications. Each cable consists of two sets of 8 colour coded 23AWG polyethylene insulated conductors. These are twisted together to form two sets of 4 pairs with varying lay lengths. These pairs are then formed around a central 'X' shaped polyethylene filler. This filler assists in maintaining and enhancing the cables performance.
