Data Cabling & Network Cabling

Network Cabling or Structured Cabling is at the core of most computer networks and is critical to network performance when systems go live. Data or Network Cabling is a specialist skill that requires the right tools and knowledge to ensure that the cabling infrastructure is deployed correctly. At 777 Networks, we specialise in delivering professional data cabling installations in Leeds and all over the UK, ensuring that your network is as effective as possible from the get-go.

Our services include:

  • Building Data Cabling Infrastructure From The Ground Up
  • Cabling For Office Space Renovations
  • Computerising Warehouses
  • Cabling To Extend The Reach Of Data And Systems In A Branch
  • Linking To Remote Sites

We use enterprise-grade components in all our Computer Network Cabling designs to ensure maximum performance, quality, and longevity. This commitment to quality helps us deliver 100% availability to any device or system that transmits across the network. 

Network Cabling Products

Cat5e:  Cat5e data cabling the cheapest and most readily available cable type. It offers data speeds of 1000Mpbs or 1Gbps (Gigabit) for a 100 metre distance. This is the most cost-effective cable for offices where regular connectivity is required for the functionality of PCs and Printers. This type of cabling is also the easiest to work with, making it the ideal choice for budget and mid-range network switches. PC’s and Laptops are usually equipped with Gigabit Speed ports, as a result, until recently, Cat5e was the most common choice for desk data cabling in offices and residential applications.

Cat6: Cat6 data cabling is an improved version of Cat5e cable. It offers better quality data transmission due to its thicker copper cores and the use of a central spline to separate the twisted pairs, offering reduced crosstalk and improved bandwidth. While still rated at 1Gbps speed for a 100 metre run, the higher cable quality means the cable can actually carry a 10Gbps (10 Gigabit) signal for up to 55 metres. The price of Cat6 cables has dropped significantly over the last few years, bringing it closer to the value of Cat5e cable. Due to the better price-quality value, Cat6 cable is now the go-to option for new cabling installation where Cat5e cable would have been previously used.

Cat6a: Cat6 Augmented, or Cat6a data cabling (or Cat6 ‘augmented’) is an upgraded version of Cat6. This type of data cable is significantly thicker, heavier, and more expensive than Cat5e/Cat6 cable. Cat6a data cable also requires special care during installation as the cable integrity can easily be compromised if not handled correctly. Cat6a cable is rated at 10Gbps for a 100 metre run, allowing for considerably higher data speeds. Because of these qualities, Cat6a is the best cable of choice for those looking to ‘future proof’ new data network installations as the use of 10 Gig equipment gains momentum and is already found in many servers and enterprise switches.

Fibre Optic Data Cabling: Fiber data cabling is used wherever copper cabling is not suitable. This includes situations where cable connections between data cabinets or devices are over 100 metres in distance, where very high data speed and high bandwidth are needed, or where interference from metal-based cabling must be eliminated. As most mid-range network switches include ports that can be used for fibre channel connections, fibre can be added to a traditional copper cabled network without having to replace any equipment.


Cabling category standards require the manufacturing process to use pure copper in the production of data cables to ensure optimal electrical conduction properties. However, there has recently been a rise in unscrupulous companies manufacturing and importing low-quality data cable that is actually Copper Coated Aluminium (CCA). This ‘fake’ cable is being sold on the internet and through electrical distributors and can lead to a number of issues during and post-installation. CCA data cable should be avoided at all costs. If you find that this type of cable has been used in an installation at your office, you should call the supplier and have it removed.

Data Cabling FAQs

Data or network cabling is used to transmit data from one source to another by way of binary electrical communication signals. Data cables can be a twisted pair, coaxial cable, or fibre optic.

There are three main types of data cables using in data/network cabling:

  • Twisted pair – mainly used in computer networking and telephony. They are mostly wired using a shielded twisted pair, which helps to reduce the amount of signal degradation from other sources. 
  • Coaxial cable – often used in older computer networks, and displaced by the twisted pair. Still used today by cable networks for television. 
  • Fibre optic cable – recommended for fast data connections. Recommended by telecommunication companies to provide fast, reliable, and more secure access to the internet/communications.

Network cabling is important for connecting and transferring data between one system and another i.e. computers, routers, and storage systems. Within a business, reliable network cabling is vital for everyday operations, unless your business migrates to the cloud.
