Best Fibre Deals 2025

1. Run a Speed Test

Before you even consider getting fibre, it helps to know the speed of your current line. Fibre is incredibly fast. If you previously had an LTE or ADSL network you’re likely to see a big jump in speed. You can measure that here. 

2. Start Your Search

There are a lot of fibre deals available. The best place to start searching for uninterrupted super-fast fibre is by searching for and comparing the options on comparison sites like this one.

When you’re looking for fibre deals the first place to start is looking for fibre in your area by using one of the handy ISP fibre coverage maps. Doing this initial search saves you a huge amount of time by narrowing down the deals that are available to you. 

How Do Fibre Networks Work?

Fibre works by passing data at extremely high speed (literally the speed of light) through a fibre optic cable. This makes the download and upload speeds of data incredibly fast. The ability to send and receive data is made possible by cables that run great distances across land and under the sea. Most of the world’s data is carried in these fibre optic cables. It’s the reason why we can load a website or stream video in South Africa from websites that are hosted around the world. Optical fibre cables are familiar, but the extension of these networks and introducing fibre to the home is relatively new.

The Travel of Light Through Fibre Stands

Fibre connections are essentially light travelling through glass fibre strands. At first, it might be hard to imagine – how can information be carried at all through light? But here’s how it works. Think of it as morse code – a series of long and short beeps – or if you like a torch flashing on and off in the dark as a pattern. Fibre cable communicates information in a similar way. The information is conveyed via pulses of light that are generated by tiny lasers known as light-emitting diodes (LEDs). At the centre of each fibre is a glass core – the tunnel or pathway in which the light travels.

Light typically travels in a straight line – so how does it get to the other side without the information being lost or damaged? Well, surrounding the core is a thick layer of glass which reflects light inward. That ensures that the signal isn’t lost as it ‘bounces’ through the glass tube from one place to the other (see our article on jitter).

Who Benefits from Fibre Internet?

Fibre optic internet is beneficial for businesses of all sizes, but the biggest winners will be those that rely on cloud computing, massive data sets, or server-based data storage. Using Voice over Internet Protocol (VoIP) over a fibre optic network gives your business an edge by giving you a more reliable means of communicating with clients and staff.

Switching to Fibre Broadband will bring you several improvements.

✔ Enhanced download speeds – fibre’s high Mbps, downloading huge files from the web or a server will be significantly quicker. With fibre, you can quickly download and upload files without any lag.

✔ Consistent Bandwidth – Bandwidth is essential for organisations that depend on several users using the internet simultaneously, whether for downloading huge files or taking part in a Voice over IP (VoIP) conference call. The bandwidth of fibre is substantially higher and can easily accommodate the activities of your business. Parallel, high-speed execution of SIP trunking, cloud applications, video streaming, and web conferencing is feasible.

✔ VOIP Calls, Teams and Zoom Meetings – Conference call latency and quality have been considerably improved. Fibre’s low latency means you can count on crystal-clear video and audio during business meetings, which in turn facilitates more productive cooperation and individual options like working from home and other forms of flexible work.
