What is Fiber to the Home (FTTH)?

Fiber is the technology of the future, transmitting data over long distances at the speed of light. But to take full advantage of its potential, the fiber cable has to be laid right to the heart of your business. That's why it's called Fiber to the Home (FTTH). Proximus is the first Belgian operator to install end-to-end fiber to the business for its customers. Most other operators, such as VOO, Orange or Telenet, claim to offer fiber, but use a coaxial cable for the last leg from the street to the home. However, these two types of connection are absolutely not equivalent. Only Fiber to the Home guarantees the best performance in terms of download and upload speeds, stability and latency . And on top of that, your business is ready for the future! While Proximus is gradually rolling out fiber to existing homes and businesses in Belgium, new building estates are usually immediately connected to our fiber network, in consultation with the construction industry.

Do all operators offer the same fiber connection?

The answer is no. Currently, the standard for "ultra-fast" or "Gigabit" Internet service is up to 1 Gigabit per second (or Gbps) download, and up to 50 Megabits per second (or Mbps) upload. Most operators, such as VOO, Orange or Telenet, claim to offer fiber, but use a coaxial cable for the last section, from the street to the home. This is not a Fiber to the home connection. Proximus, for its part, installs fiber right into its customers' business. The fact that the fiber cable is connected directly to your home means that you have your own cable, not shared with your neighbours. So you're totally independent of any external interference factors. And that makes all the difference, because you get an ultra-stable connection and the fastest Internet in the country, with download speeds of up to 8.5 Gbps and upload speeds of up to 8 Gbps. And that's just the beginning! By opting for this cutting-edge technology, you're ready for the future. But what does this mean in practice? Imagine you want to download the Lord of the Rings Trilogy (30 GB): while a 1 Gbps connection allows you to download it in 4 minutes, an 8.5 Gbps connection allows you to do so in just 24 seconds.

Do I really need such speeds?

If you're wondering who needs these speeds, you might be surprised! Today, 1 Gbps has become the norm but we are asking more and more from our Internet connection. The needs are constantly increasing and with the technological evolutions (4K, 8K, virtual reality, …) and the numerous connected objects that are developing at a lightning speed, fiber technology is the solution. It allows you to meet the current needs but also to prepare for the next 70 years. It not only allows you to be more efficient but also to save time.

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.
