How do I get fiber?

Questions that you may still have

As a technology of the future, fiber transmits data over great distances at the speed of light. The advantages are numerous, including a super-fast and much more stable Internet connection.

Proximus is modernizing its network (teaming up with other partners such as Fiberklaar and Unifiber) and is gradually replacing its current copper cables with fiber cables. Ultimately, the Proximus copper network will be completely replaced by this new technology.

Thanks to a close collaboration with the construction sector, most new housing estates and apartment buildings are swiftly connected to our fiber network.

And unlike most other operators, Proximus takes the fiber right into your home. This guarantees you the best possible performance, today as well as tomorrow.

Find out more about this new network

With fiber, you'll have access to super-fast and stable Internet, ultra-low latency, a sharper than ever image on all your screens and, most importantly, you'll be equipped for the future:

  • Super-fast, stable Internet: no downtime or slowdowns when importing or exporting documents, watching videos and playing online, no matter how many people or devices are connected at the same time.
  • Ultra-low latency: latency is the delay between a data transfer request and the response to that request. After all, when you play online, every millisecond counts. With fiber, you stay one step ahead of your opponents.
  • A sharper picture than ever before on all your screens: TV, tablet or smartphone, with fiber, you won’t miss even the tiniest detail.
  • Future-proofed: tomorrow, your home will be increasingly connected thanks to the Internet. With fiber in your home, this evolution is child's play.

Already a Proximus customer? Your current copper cable will soon have to be replaced by fiber anyway. Fiber meets the need for ever greater connectivity. It guarantees you better performance today and tomorrow.

Mbps is the unit that measures the amount of data transferred in one second. This measuring unit for data transmission is used worldwide to quantify Internet speeds. Mbps stands for megabit per second. Gbps (or GIGA) stands for gigabit per second. One gigabit (or 1 GIGA) corresponds to 1,000 megabits, which is very fast!

The speeds advertised by Proximus correspond to download and upload speeds. When a fiber product claims Internet speeds of up to 1 GIGA, this means that the connection is capable of downloading up to 1 gigabit of data per second. With a 1 gigabit per second connection, you can download a 1.5 gigabit movie in just 12 seconds. At traditional speed (70 Mbps), this download takes you almost three minutes.

Faster and more stable, fiber is also more environmentally friendly. It uses up to 12 times less energy to send data than your current copper cable! Switching to fiber makes sense for the environment and the climate.

Fiber consists of glass made from silicon dioxide, the most abundant element on earth after oxygen. It is found in sand, clay, rocks and even water. Its mining is not harmful to the environment.

Compared to copper, the production of fiber has a small environmental footprint: 0.06 kg of CO2 for glass fiber compared with 1000 kg for 2 kg of copper wire (used for your current connection).

Finally, Proximus recycles up to 500 tonnes of copper per year to give it a second life.

The fiber cables are laid district by district and street by street. In order to bring the fiber right into your home, preparatory work is required, such as excavation or façade work. We will do our utmost to minimize any inconvenience and will always keep you informed of the timeframe.

Once the work in your street has been completed, the fiber cable will be brought to your home discreetly. From that moment on, you will be invited to switch to this new technology and enjoy all the benefits of fiber. Once you have placed your order, one of our technicians will come to your home on the agreed day to install your fiber connection box.

If you live in a building managed by a property manager, the latter must first give us access to the building to install the fiber in the common areas. Only then will you be able to request your connection to our fiber network.

All about installation

Yes, your fiber connection is completely  for every activation of a Flex Fiber package, whether you are a Proximus customer or not. In the cities where Fiberklaar is laying down the fiber network, please also refer to their conditions ( window). If you opt for another solution, such as Internet Fiber alone, for example, installation fees of €59 will be charged for any new installation.

Where is fiber available?

Thanks to our partnerships with Fiberklaar in Flanders and Unifiber in Wallonia, the roll-out of fiber will pick up speed in the coming months and years, in order to offer you the best network available. The aim is to provide an ultra-fast and stable network that can easily absorb the data traffic that will continue to grow in the years to come.
