The 3 advantages of Fiber to the Home

Ultra-fast Internet

Unmatched speeds so you can download and upload documents, photos, series or games in no time.

Ultra-stable connection

A flawless connection for the whole family, on all your connected devices, and anywhere in your home.

Ultra-low latency

Almost instantaneous reaction time with no lag or interruption to give you the edge over your opponents.

Proximus fiber, directly to your home, is the best

Proximus and its partners (Fiberklaar, Unifiber, GoFiber) are the only Belgian operators to install end-to-end fiber on a large scale, right to the heart of your home, unlike most competitors who use coax cables for the last few meters. It makes all the difference in terms of speed, stability and latency.
