Cat5e Cabling
 
Despite the introduction of higher performance cabling such as CAT6, CAT6a and CAT7, CAT5e remains the most popular and commonly deployed ethernet cabling standard.
 
There are various reasons for this, and why there is a widely held belief that CAT5e is here to stay - at least for longer than its predecessors. The main reason for this is that it supports gigabit networking and so theoretically, if used exclusively with gigabit network cards and switches, will support higher data transfer across the network.
 
However, the emergence of CAT6 has facilitated a far more effective platform for gigabit networking due to its decreased data loss. So in reality if there is a genuine requirement for gigabit CAT6 is the category of choice.
 
But gigabit networking is only relevant when large amounts of data, for example large image files such as 3D need to be rendered across the network. For most business users who require internet, email and access to documents in programs such as Word or Excel, users will rarely benefit from the advantages of gigabit networking therefore CAT5e is an ideal infrastructure.
 
CAT5e has benefits of its own to recommend it. It is more economical to install, and moreover it requires less space than the higher diameter CAT6 and is more tolerant of tight bends and therefore easier and faster to install in trunking and where space is limited.
 
Cat6 Cabling
 
While CAT5e can facilitate the transmission of data packets at gigabit speed, it is limited in the amount of packets it can cope with, resulting in data loss. Because reliable protocols such as TCP resend lost packets this results in the user experiencing a slowdown over the network, for example when opening a large graphics file.
 
By utilising all four pairs within the cable, increasing the frequency of the twists in each pair and reinforcing the cable with a plastic spine, CAT6 reduces the amount of "cross-talk" that cause this level of data loss.
 
So who does need CAT6? Certainly anyone rendering large graphics file over a network - some 3D CAD programmes can produce files measured in gigabytes - such as architects, structural engineers, in fact any designers or technicians that work with large files. There is the issue of future-proofing. There is no doubt that networking has benefited enormously from the increase in data transmission speeds from 10 mbps to 100mbps and there is no reason to believe that 1000mbps will not be considered the norm a few years hence.
 
CAT6 costs about 30% more than CAT5e, so is it worth the extra expenditure if all you anticipate using in future are internet, email and basic documents and spreadsheets It is also worth bearing in mind that data will only cross the network at the speed of the slowest network device which means possible investment in gigabit switches and NICs to enjoy the full benefit of gigabit networking over CAT6.
