‘Which Category Cable Do I Need?’
It's a question we often get asked, and it can definitely be a tricky area to navigate for some people.
The simple answer is that there is no simple answer to this. Ultimately, the best cable largely depends on what application it will be used for, where it will be installed, and what screening options will be needed.
Ultimately, the most important factor to consider is whether the cable you select is going to be capable of the performance needed. This handy guide is designed to simplify the selection process for you: SEE 'CABLE SELECTOR' TABLE BELOW
Whilst performance levels need to be met, you don’t want to over specify either, unless the need to futureproof is evident from the outset. Why use cables that give data centre level performance when your installation is in fact designed to provide telephone and video signals in a domestic setting? All Category data cables are required to meet or exceed the requirements within ISO11801, BS EN 50173, and ANSI/TIA[1]568 (Cat 7& 7A is not recognised by this) standards as 100 Ohm twisted pair.
Fire performance is also critical to all internal cable installations. If BS6701/7671 is being used within an installation it is worth taking into consideration the CPR classification required. Outdoor versions of all the cables highlighted are available, however, due to the delicate nature of the products, more robust processes can affect the performance of the cables and it’s worth checking the specific requirements before installation takes place.
It is possible to combine new cables with legacy equipment that is still fully operational, as higher channel cables are backwards-compatible with lower channel products. Do remember though, that overall system performance will only be as good as its weakest element!
