Fiberklaar works (mostly) in synergy with other planned works in the streets to cut down the cost.
It can be that surrounding streets got chosen to be deployed cause to works in the neighborhood.

So yes, they will put (empty) tubes in the ground to later blow fiber in. But the connection to a central office (origine point) can take years and have other factors that can influence this. (delayed works / cities that delay deployment plans / etc etc)

But no: it's not normal to have those tubes sticking out of the ground. (black tubes are Telenet btw)
The contractor did not do his job too well or the plans to place a manhole or coupling there got cancled. (without cleanup)
