Fiber optic connection is being installed - use existing multi-utility infrastructure?

Hello everyone,

our village will be equipped with fiber optics over the course of the year, and I am wondering where the cable should best enter our house.

To explain: on the left side of the plan next to the house runs the street directly (40 cm splash protection strip, enclosed with concrete edge strips, then 1 meter of water-bound path surface, then the single-lane street). At the bottom of the plan is the paved driveway/parking space.

According to the information from the fiber optic provider, the connection should be carried out as follows:

Very often, the house connections are made using the so-called earth displacement method, so no digging is necessary. This means that an underground earth rocket is "shot" to the house or a flush drilling is carried out to lay an empty conduit up to the house. For this, only two access holes are necessary: one at the street to connect the house connection with the main line and one directly at the house. If this closed construction method is not possible, in rare cases open construction is used. In all procedures, work is carried out at a depth of approx. 60 cm. The fiber optic cable is then blown into this empty conduit in a later step.

No worries! The front yard or the paved driveway are usually not affected at all. If they are, everything will be restored to its original condition.

A small hole will be drilled through the house wall in the basement or on the ground floor so that the fiber optic cable can enter the interior of the house. The hole will be properly sealed.


According to initial reports from neighboring villages, it rather runs in a way that the construction workers come unexpectedly and then never work with earth rockets ;-)

So now my consideration:
can/may the construction workers use the still unused element of the multi-utility house entry? Since this is the standard way to get utilities into the house, this would be the obvious choice, right?
Alternatively, it would of course also be possible to drill directly from the street side, above the washbasin on the plan into the house – as long as they manage this so precisely by the centimeter that they do not drill into the water pipes :-8
In the technical room both positions would be equally okay for us; on/ in front of the wall at the bottom of the plan, there are multi-utility, water meter, distribution box, telephone connection installed. Basically there is still enough space for the house transfer point and network termination device – provided the fiber optic provider does not have further specifications regarding the distance to the aforementioned installations.

What speaks for or against which variant?

Thank you very much!

I'll jump on that, I'm interested in it too.

We have also recently gotten fiber optic. It was also pulled into the still free multi-duct at our place. So the ground only had to be opened up shortly before the house and the empty conduit of the multi-duct had to be found. Then the cable was simply pushed through. That's better than having to drill through an exterior wall somewhere again.

our village will be expanded with fiber optic over the course of the year,

We walked through a village on Sunday where one could get the impression that "Glasfaser" was a party and the state election was coming soon ;-)

can/may the construction workers use the still unused element of the multi-service house entry?

The fiber optic cable is a light waveguide. It does not get warm and has no electromagnetic interaction with television or telephone cables made of copper or also fiber optic. Therefore, I see no obstacle to an immediately adjacent house entry in the same service duct.

Hi, I only have fiber optic in the new building. I didn't even have Telekom installed. It's also included in the multi-utility pipe.

Multi-utility installations are relatively modern stuff. If I, as a glass retrofit installer, draft a guide for homeowners, it may be that this variant does not receive any attention because it is too rare. But that does not necessarily mean that they do not want to use the existing multi-utility house entry at all.

I would simply discuss it with the supplier. As long as another utility is still free, that should be the logical solution. However, without excavation, it won't work, unless the position of the free utility is known exactly.
