Cat6 has been the cabling system of choice for many years.
Cat6 was designed to run the same Ethernet protocols as Cat5e, but it’s a higher performance system, supporting more than double the frequency and running to a tighter specification.
This gives it significant performance headroom to support the faster protocols like 1000BaseT and is therefore considered more reliable than Cat5e.
An expertly installed Cat6 system can run 10GBaseT over lengths of up to between 30 and 45 metres. However, this is not guaranteed and depends on the installation being ‘tweaked’ to pass.
More than 95% of Cat5e and Cat6 installations in the UK are unshielded (U/UTP) which are easier to install and maintain than shielded systems.
