Cat6 vs Cat6A: Choosing Network Cabling

The Cat6 vs Cat6A decision starts with your target applications, cable routes and planned upgrades. Compare the complete installed system rather than the price of a cable box alone.

Cat6 vs Cat6A: start with the target application

Cat6 is commonly used for Gigabit Ethernet installations. Cat6A supports 10GBASE-T over a compliant channel of up to 100 metres. Do not assume that an existing Cat6 installation will support 10 Gigabit Ethernet over the same distance; have its suitability assessed for the intended application.

The channel includes connecting components and patch cords. A 100-metre channel limit does not mean a 100-metre fixed cable run plus additional leads. Confirm the permitted design for your cable and link arrangement.

Cat6 vs Cat6A: specify a complete system

Next, ask for compatible cable, jacks, patch panels and patch cords, together with the installation and test specification. Installing Cat6A cable alone does not establish Cat6A performance if other parts of the link do not meet the requirement.

For the Cat6 vs Cat6A comparison, check conductor size, outside diameter, bending requirements and termination compatibility against the selected products. Allow the installer to assess pathway capacity before accepting an upgrade that changes the physical cable arrangement.

Compare the project cost

Finally, request separate costs for cable, connecting hardware, patch cords, installation and certification. If cable routes will become difficult to access, include that constraint when weighing future requirements against the initial budget.

For an office brief, state the required speed at each outlet and the likely upgrade horizon. Ask the supplier to explain which tested configuration meets that brief. Category labels describe the cabling; the connected switches and devices must also support the intended speed.
