Fibre vs. ADSL

ADSL & Fibre Compared

Since 2015, fibre internet has been bringing faster download speeds to users across South Africa.

But what exactly is the difference between ADSL and fibre internet? Here’s how fibre differs from ADSL in terms of speed, reliability, and cost:

Internet speed

Internet speed refers to the speed at which information or data travels from the web to the device that is connected to it. It is calculated in megabits per second and the downloading speed is often higher than the uploading speed.

ADSL uses telephone lines to transmit data along copper cables from your nearest telephone exchange to your home or office. There are two things that can slow down your ADSL internet speed:

  1. Distance from the exchange. The further you are located from the exchange, the further the data need to travel, and the slower your internet.
  2. Traffic. Copper cables are easily affected by bottlenecks and the more traffic the copper cables are experiencing, the slower your connection.
How long will it take to get connected?
This will depend on the turnaround for your installation and activation. Once the line has been installed in your premises it can take up to 5 days for the provider to activate your line. As soon as your Fibre line is active, you can be connected to the internet by your ISP within 24 hours.
Can I use my current DSL router?
Since Fibre works very differently to DSL, the answer is probably no. It all depends on the router and how your provider installs fibre.
How is fibre different from DSL?
DSL is dependent on Telkom copper wire infrastructure, which is often unreliable and can be slow if you have a bad line or are far away from your local exchange, whereas Fibre transmits data with pulses of light over an optical cable.
How fast is fibre really?
The fibre access circuits feeding your house will be configured to deliver information at speeds up to 1 Gigabit per second, which is about 500-1000 times faster than your average ADSL line when it comes to download speed.
Can my existing landline number be ported to the fibre provider?
Yes, your number can be ported to any ISP that offers VoIP services.
What does uncapped mean?
Uncapped internet means that you can use as much as you need, without your data ever running out.
