Cat6A (Category 6A, Augmented) is an enhanced copper Ethernet cabling standard specified in TIA-568-C.2. It delivers 10-Gigabit Ethernet performance across the full 100-meter horizontal channel distance — and it's the only copper standard that does so reliably. Cat6 can support 10G, but only to approximately 37–55 meters depending on cable quality and environment, making it impractical for most commercial floor plans where runs regularly exceed that distance.
The "augmented" specification means Cat6A adds four important improvements over Cat6: a higher frequency rating (500 MHz vs 250 MHz), mandatory alien crosstalk (AXT) specifications that prevent interference between adjacent cables, a larger conductor diameter that handles PoE bundle heat better, and support for IEEE 802.3bt PoE++ delivering up to 90 watts per port — the standard required for enterprise tri-radio wireless access points, pan-tilt-zoom cameras and other high-power commercial devices.
For any new commercial buildout — offices, healthcare, retail, data centers — Cat6A is the right choice. The incremental cost over Cat6 is small relative to the total project cost and eliminates the risk of needing to recable within the infrastructure's expected lifecycle when wireless density, device counts or switch upgrade cycles demand 10G to the edge. Cablify installs Cat6A for all new commercial projects.
