NM Cabling are here to assist you in protecting your computer technology. We can help to increase data transfer speeds, ensure efficient communications within your commercial building, and protect data integrity. To protect your investment in computer technology, your computer cabling must be correctly installed, tested, and maintained by an experienced company with the ability to prioritise your requirements.

Computer Cabling Services

Computer cabling is a term widely used to describe all types of data cabling associated with computers and data transfer. For instance, Ethernet cabling, internet, and various types of telecommunications and networking. At NM Cabling we install and maintain industry leading types of computer cabling to provide a broad networking solution that will keep your data flowing and guarantee you peace of mind while you operate your business.

Computer data cables form local area networks (LANs) between computers in the same area. Thus, allowing them to directly communicate and share data with each other. Ethernet Network is a platform on which LANs are hosted. In addition, this is only possible when the data cabling is installed carefully and correctly.

Did you know – 50% of downtime experienced by companies is directly attributed to bad cables or poor installation.


Data Cabling Functions

All computer cables have common functions and traits. The cables create physical connections between ports through which data can be transferred electronically. Furthermore, the purpose of a computer cable is to transfer data, which can then serve multiple functions. For example, many modern telephone systems are run on a single computer cable along with the PC

Development of Computer Cabling

Telegraph lines we used to facilitate telecommunications. Alexander Graham Bell used them to make the first telephone call. The telegraph lines transferred data through copper wire and utilised single- wire earth return circuits. In the 1880s these circuits were replaced with balanced circuits.

With the popularity of the telephone increasing, interference between the copper wires started to become an issue. As a result, this led to the invention of twisted pair cables. Twisted pair is when copper wires are twisted around each other. Furthermore, each pair has a unique twist rate, this is to prevent signals from getting mixed. This technology is still in use today. The advancement of technology has allowed these cables to become faster and capable of spanning long distances. However, the original premise behind twisted pair cables has not changed.

As technology advances, computer cabling progresses with the changes. The most recent invention is fibre optic cables. These cables are widely recognised as a superior alternative to copper. In addition, fibre optic cores are made of glass or plastic and carry rays of light over long distances. Fibre optic is extremely quick and immune to electromagnetic interference.

Types of Computer Cabling

To compare the data cabling below please review our article What is the difference between Cat5 Cat6 Cat7 Cat8 Cabling?

Cat3 Data Cable (no longer used)

Chances are you’ve never heard of this cable before. Cat3 cables were popular in the 1990s but are no longer used today. The cable is a copper twisted pair that can transfer up to 10Mb/sec, the maximum bandwidth is 16MHZ.

Cat5 and Cat5e Data Cables

Cat5 was the category before Cat5e, it’s a twisted pair cable. This cable is not widely used with today’s technology. However, Cat5e is still in use and its mainly used for Ethernet. The cable can transfer up to 1000Mb/sec (1 Gigabit) with a bandwidth of up to 100Mhz

Modern installations are generally a minimum of Cat6 or even Cat6a cabling. However, Cat5e cabling is still very much a popular choice for restricted budgets or when adding additional cabling to an office that already has Cat5e computer cabling elsewhere

Cat6 and Cat6a

Category 6 and 6a are widely used by various companies due to the high performances they offer. The cables have a bandwidth of 250Mhz and 550Mhz. with transfers of up to 10Gbps. This cable is the go-to data cable for many business requirements.

Cat6 is restricted to 10 Gigabit up to 55 metres so whenever planning is made for 10 Gigabit speeds, Cat6a cabling should be the recommended installation. With more and more requirements for 10 Gigabit for computer cabling, our first design choice would be Cat6a cables but then considering Cat6 if such speeds are not required or budgets are restricted

For a more in depth article on the differences between Cat6 and Cat6a cabling please read What’s the difference between CAT6 cable and CAT6a cable

Cat7 & Cat 8

These cables are not as popular as those above when it comes to computer cabling.  The reason is due to their high performances the cables are more expensive in comparison and computer cabling just doesn't need that performance. These cables are generally found in data centres for cabinet to cabinet links or in specialised cabling environments.

Cat7 and Cat8 cabling has the following performance

  • Cat 7 – 600Mhz and up to 10Gbps
  • Cat8 – 2000Mhz and up to 40Gbps

Fibre Optic Data cables

Fibre optic is generally the backbone cabling linking the data network switches together which in turn operate the computer cabling.

Fibre optic cabling has a greater bandwidth than copper cabling and is thus suited to linking together cabinets, switches and communication rooms due the the transmission bandwidth it provides

Thee is two categories of fibre cabling which are

  1. Singlemode Fibre Cabling - OS1, OS2
  2. Multimode Fibre Cabling - OM1, OM2, OM3, OM4

In some cases fibre cabling is used direct to the desk (FTTD). However, this is usually part of a specialist installation such as emergency or security services where they require their computer cabling to be highly secure and restrict outside listening to its transmissions

Installing Copper and Fibre Cabling

The installation of computer cabling should not be taken lightly. The process is very important for several reasons. For instance, a network can’t be functional if the cables are not installed correctly.

Poor installations can lead to noise on the cable, packet loss, drop outs and slower speeds.

Additionally, failure to correctly label and document the data outlets will cause issues when fault finding, potentially costing your business more money.

You should ensure the following are undertaken as part of any data cabling installation

  1. A computer cabling design to incorporate all outlets throughout the building allowing for todays requirements and future expansion
  2. Base the cabling choice on the transmission speed required. For example, if you require 10-Gigabit speeds design to install Cat6a
  3. Check manufacturers requirements so you install enough cables to each device. Some Wi-Fi access points require two data cables for example
  4. Ensure the existing containment is suitable for the cabling design and plan for additional as required
  5. Plan for large enough cabinets to contain your cabling and hardware
  6. Once Installed ensure each cable (fibre and copper) is tested with a cabling certifier such as a Fluke DSX 
  7. Use printed labels on Patch Panels and Modules to identify outlets
  8. Mark up drawings with outlet numbers and cabinet locations
