Questions that you may still have

What is fiber exactly?

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.

Why go for fiber?

Your current copper cable will soon have to be replaced. Fiber, which will be rolled out instead, meets the need for ever greater connectivity. It guarantees you better performance today and tomorrow.

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.

  • A sharper picture than ever before on all your screens: Whether on TV, tablet or smartphone, with fiber, you won’t miss even the tiniest detail.
  • Future-proof: tomorrow, your home will be increasingly connected thanks to the Internet. With fiber in your home, this evolution is child's play.

Are you already a Proximus customer? At some stage, your current copper cable will need to be replaced. Fiber, which will succeed it, meets the ever-increasing need for connectivity. It guarantees you better performance today and in the future.

How to ask for fiber as a tenant?

As a tenant, all you have to do is submit your request to Proximus. The landlord cannot oppose the choice of operator, nor the installation of fiber at the request of the tenant. We nevertheless advise you to inform the landlord.

In a building in co-ownership, all owners will normally have already been notified of the arrival of fiber in the building through the general assembly or by the syndic/building manager.

All about installation

Is fiber more environmentally-friendly?

Faster and more stable than traditional copper cabling, fiber is also more environmentally friendly.

It can be entirely produced in Europe and consists of glass made from silicon dioxide, the most abundant element on earth after oxygen. This resource is found in sand, clay, rocks and even water. Mining it is therefore not harmful for the environment.

Moreover, fiber uses 4x less electricity than copper, and its production leaves a very small environmental footprint: 0.06 kg of CO2 for glass fiber compared to 1000 kg for 2 kg of copper wire (used for your current connection).

Switching to this future-proof technology makes sense for the environment and the climate!

Watch a video on why fiber is environmentally friendly.

How long does the installation take?

The installation takes between two and four hours, but don't worry, the connection is only cut off for a few minutes. So you can continue your activities without any problems.

For new housing estates and apartment buildings, which are usually already connected to our fiber network, the technician only activates your services on the fiber network, which takes much less time.
