Our Cat6 UTP patch cables are constructed with 24 gauge copper wire to support a broad range of Ethernet applications such as Power over Ethernet (PoE). Because we use a high quality UL Listed 24 gauge insulated copper wire our cables easily sustain the nominal voltage (48v) capability required for Power over Ethernet applications whereas the inferior quality offered by copper-coated aluminum cables may be subject to insufficient power delivery heat buildup and potentially equipment damage. StarTech Category 6 Patch cables are constructed with top quality components. The Strain relief prevents the cable from being bent at sharp angles at the connector to minimize the stress at the plug termination point. Colored Hoods for departmental color coding. StarTech Category 6 patch cables are carefully constructed and tested to keep the Near End Crosstalk (NEXT) well within acceptable limits.
