Three different performance levels are available - Solution 6, System 6, and Premium 6 - offering various levels of margin to industry standards. Solution 6 cable eliminates the central isolation member common to many category 6 UTP cables, providing a more economical option while reducing overall cable diameter. This reduces pathway size requirements, carton materials and provides more efficient shipping options for a greener installation. System 6 cable provides significant headroom above all TIA and ISO/IEC category 6 transmission performance specifications. Premium 6 cable offers even more headroom above industry standard transmission levels, yielding a high level of immunity to installation variables ensuring reliable application support over the life of your cabling system. Combine one of these category 6 UTP cables with Siemon high performance category 6 connectivity and the result is a system with superior electrical performance. Siemon also offers category 6 cross-connect wire for use with connecting block applications.Main FeaturesCMP Nominal Jacket OD: 5.6mm (0.22 in.)CMR Nominal Jacket OD: 5.2mm (0.21 in.)
