What is data cabling?

4th September 2025

Not sure what most of the cables in your building do? Don’t panic! We explain how everything is connected.

For devices to be able to communicate, there needs to be a connection. Sometimes, this connection is wireless; in other instances, however, it is physical. Data cabling is the term we use for the system of wires that connects your devices to each other, as well as the internet and other internal networks. 

Without proper data cabling, your PC, servers, switches, routers and other devices are all isolated – this wiring brings them together, so you have access to everything you need. Take a look at the key components:

Cables: this can include ethernet cables (most commonly used), fibre optic cables (used for ultra-fast/long distance transmission) or coaxial cables (older technology but still used in some setups). This is how information travels from A to B.

Connectors: these connect A or B to the cables, allowing transfers to occur. RJ45 is standard for ethernet cables while LC, SC or ST can be found for fibre optic cables.

Patch panels: this is the central hub where the cables end.

Switches: this controls and directs data traffic between the devices.

Ideally you want your data cabling to be well structured and organised, so that you can easily identify important wires in case you need to troubleshoot an issue down the line. It will result in more reliable connectivity, faster data transfers, easy scalability and better security.

Sometimes issues can occur – cables can degrade or be installed incorrectly: you need to plan to achieve the best results. Consider how man workstations you have, the route you’d need to take and if any work will meet compliance standards.
