Cable Showdown: Cat6 vs. Cat6a

Cat6 and Cat6a may be two of the most popular standards for Ethernet cables, but how do you decide between them?  Depending on your application, one may work better than the other. To help you decide, we thought we’d stack them up side-by-side for a showdown.

Both Cat6 cables and Cat6a cables offer speed, flexibility and cost savings. They can both be used for PoE applications and are ideal for transmitting voice, video and data, though Cat6a is able to move larger volumes of data. Cat6 cables are great for connecting access points and other devices including media converters, switches and wireless controllers that are typically running at 1Gbps speeds. Cat6a cables are typically used in data centers and storage area networks (SAN) that require 10Gbps connectivity or more through trunked 10Gbps connections.

The cost difference between the two is minimal. The main difference is that Cat6a is able to transmit at 10 Gbps supporting 10GBASE-T over longer distances than Cat6 cables. Cat6a also builds upon Cat6’s capability to protect against alien crosstalk, which improves performance. Though if a shielded cable isn’t necessary and a lighter option would work best, unshielded Cat6 has the advantage. As always, the requirements of your application will dictate which cable to use.
