CAT5e vs CAT6 …

Network cable technology keeps improving with new standards introduced for the cabling of your network sockets.

This is a brief overview of the options for your network cabling, based on our extensive experience.

If the work is within a new building or as part of a refurbishment scheme, you may also need to comply with CPR = Construction Products Regulation.

We provide advice and priced options to help you choose the most appropriate solution, for your requirements and budgets.

Top Tip: Be aware of copper clad aluminium (CCA) cable, although tested in a laboratory it will result in future issues!


This is the most common cable grade, providing Gigabit Ethernet support at the lowest cost.  It is also the easiest cable to fit and terminate correctly, so reduces the risk of problems.

Devices are supported for total distances (including leads) of up to 100m, although for longer runs, especially those requiring support for power (wireless & CCTV), we will recommend CAT6.


CAT6 has been adopted as the minimum standard for network cabling by many clients.

Due to the increased size of these cables, containment must be planned more carefully, otherwise it may be used for all general requirements.

The size is due to the construction including a greater use of copper, thus improving transmission of PoE, especially over longer lengths.

If you are utilising green technology within your network switches (that reduce the power to ports based on the quality of the connection), CAT6 technology is ideal, as there is less signal loss than a CAT5e alternative.


We provide CAT6a connections for high speed (10 Gbps) devices (normally servers) although this technology has also been beneficial for clients transmitting high quality images.

As CAT6a is the bulkiest of cables and requires care when planning routes and it must be fitted carefully to ensure the performance is achieved.
