STRUCTURED DATA CABLING

Voice and data network cabling is the foundation for a business’ IT and communications traffic. It is a critical investment which enables a system to support new technology and advances for the duration of the infrastructure lifetime.

“Structured cabling systems” is the networking term that describes the cabling used for data and telecoms. Once installed, structured data cabling is used to link numerous network devices throughout a building, simplifying the process of sharing data and information. If you are not using the correct structured data cabling, you may not be getting the most out of your technology. To ensure that you are receiving the best quality connections available, we will provide you with a specific assessment of your cabling requirements and install structured data cabling that will suit your particular network.

Your business’ communication will benefit by installing structured cabling systems. The likelihood of experiencing regular technological problems with your telephone or internet will be reduced significantly. Instead, structured cabling solutions enable you to attain faster services, the ability to use them wherever and whenever, and services that are clearer and up to date.

Our Solutions

We offer a choice of structured cabling solutions such as:

  • Cat5e, Cat6, Cat 6a, and Cat 7 data cabling
  • Telecoms incorporated over LAN (either VoIP or existing analogue system)
  • Fully matched end-to-end solution providing maximum performance and reliability
  • Total support from our dedicated trained staff and approved service partners
  • Comprehensive parts and labour warranty

Structured cabling solutions will allow you to get the best out of your telephone and internet connections. As we have been providing companies with efficient network cabling for over 20 years, we understand how important communication is to your business. Unlike many of our competitors, we will not just sell you any old cable to make a profit. We will install your structured cabling solutions and ensure that you are using the correct structured data cabling to match your network’s needs.

FIBRE OPTIC CABLE

Fibre Optic data cable a technology that uses glass (or plastic) threads (fibres) to transmit data.

High speed and reduced data loss can be achieved over greater distances with Fibre optic cable.
Fibre optic cables are less susceptible than copper cables to interference.

Single and Multimode are two basic types of fibre optic.
Multimode types OM1, OM2, OM3 and OM4.

Single Mode is used when even greater distances are necessary.

Multimode fibre optic cable can transmit data up to distances of 300m at 1000mbps (4 to 24 core).

We supply and install, terminate, splice and test all types of fibre cabling.

CAT5E CABLING

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

We are often asked – “Why CAT6?” After all CAT5e superseded CAT5 because it would support 1000mbps (gigabit) networking so why the need for a higher standard? It is a legitimate question and to fully understand the answer it helps to understand the basics of network protocols.

Put simply, 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.

In other words Cat5e and CAT6 are like two highways with the same speed limit, but the CAT6 highways has many more lanes so traffic jams are less likely. Techies please excuse the over-simplification but as an analogy we think this works!

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. Then 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 20% 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.

CAT 6A & CAT 7 CABLING

What is Cat6a
In 2008, the new Cat6a and corresponding ClassEA standards were ratified. A Cat6a cabling system is a higher specification than Cat6 and designed to meet all of the requirements of the 10GBaseT Ethernet over the full 100 metre, 4 connector channel. Cat6a is backwards compatible with Cat6 and Cat5e.

The CAT7 cable standard has been created to allow 10-gigabit Ethernet over 100 meters of copper cabling. The cable contains four twisted copper wire pairs, just like the earlier standards. CAT7 can be terminated either with RJ-45 compatible GG45 electrical connectors which incorporate the RJ-45 standard or with TERA connectors. When combined with GG-45 connectors, CAT7 cable is rated for transmission frequencies of up to 600 MHz. When combined with TERA connectors, CAT7 cable is rated for transmission frequencies above 600 MHz.
