Cat6 vs Cat6a

Today, like most days, we have been installing Cat6 A data cabling to improve performance across a clients network.

A question we get asked a lot is ‘What is the difference between Cat6 and Cat6a?’

Essentially the short answer is that it is an upgrade on Cat6 cabling and offers greater performance across the board. However to go into a little more detail, the key things to be aware of are that;

  • Cat6a will support up to 10 Gbps of data transfer. Cat 6 will only support upto 1 Gbps of data transfer. It can achieve these speeds due to its capacity to operate at 500 Mhz whereas Cat6 operates at 250 Mhz.


  • Cat6a offers thicker shielding and as such greater protection from alien crosstalk – when signal from one cable interferes with another – as a result CAT6a is around twice the thickness of Cat6. The reduction of crosstalk interference means that your network isn’t prone to fluctuation in terms of spped when it comes to data transfer.


  • As you’d imagine when looking at purchasing a superior product you do have to pay the price. It is one of the more expensive data copper cable you can use but with the greatly increased performance specs it is more than worth the additional spend.


Due to the increased benefits it is a bit of a ‘no brainer’ to future proof yourself and opt for Cat6a over Cat6.

It is particularly effective for end users transferring large amounts of data for example the in the field of video editing, audio editing and large files used in high end creative design.
