Cat6 or Cat6A: which should you use?
Short answer: Cat6 is the right choice for most homes and businesses: it carries gigabit speeds over the full 100 meters and powers cameras, phones and access points. Choose Cat6A when you need 10 gigabit over longer runs, such as between network closets or for high-speed access points.

Speed and distance
Both cables carry 1 gigabit per second over the full 100 meter (328 foot) channel. For 10 gigabit, Cat6A is rated for the full 100 meters, while Cat6 is limited to shorter runs, commonly cited as up to 55 meters (about 180 feet) depending on conditions.
Bandwidth rating
Cat6 is rated to 250 MHz and Cat6A to 500 MHz. The higher rating and better protection against crosstalk between neighboring cables is what lets Cat6A carry 10 gigabit farther.
Size and cost
Cat6A is thicker and stiffer, takes more room in conduit and wall boxes, and costs more per foot to buy and terminate. In tight walls or long pulls, that difference matters.
Power over Ethernet
Both carry Power over Ethernet for cameras, phones and access points. In large bundles carrying high PoE power, Cat6A's larger conductors handle heat better.
Our usual approach
Cat6 for drops to cameras, phones, access points and workstations, and Cat6A for backbone links where 10 gigabit is needed now or likely later.
Frequently asked questions
Is Cat6 fast enough for a home?
Yes. Cat6 carries gigabit speeds over full-length runs, which is more than most home internet plans deliver.
Is Cat6A worth it for future-proofing?
For backbone runs and high-speed access points, it can be. For most individual drops, Cat6 is plenty.
