ᐅ Category 7 network cable running underground from the main house to the extension

Hello!

We want to set up a network for an extension that is currently being renovated.

At the moment, there is nothing there.

In the main house next door, there is only a Fritzbox so far.

My question is, how to best route multiple duplex cables through a conduit about 5 meters (16 feet) long underground. (Length, not depth)

Also: how does the “connection” in the extension typically look, how do you enter the building from the conduit, etc., maybe someone has experience with this.

In the extension, the cables should be distributed to 3 rooms, with 2 dual network outlets each. So, we are talking about 6 Cat 7 duplex cables.

Can the electrician install the network outlets right next to the power outlets? Joint installation of network and electrical cables is allowed.

I feel confident handling the patch panel setup, connecting the switch (in the main house by the Fritzbox), etc., myself. Although dividing the switch (main house) and patch panel (extension) would be an option—since that would mean running only one cable into the yard—I actually prefer not to do that because of data throughput and to keep everything centralized.

I look forward to your ideas and constructive contributions!

Not without separation!

Dig a trench, install wall sleeves, lay empty conduit (thick enough to later replace Cat cable with fiber optic), pull in two Cat 7 underground cables (one as a spare/reserve), install a switch in the extension, and distribute to all required locations from there.

I know that, and hopefully the electrician does too.

If I have an underground cable, do I no longer need a conduit because that’s sufficient?

Can I use installation cable in the extension? That won’t work with the switch, as it’s missing a patch panel.

In cases like this, always pay attention to potential voltage differences between the buildings!

So, do I need an equipotential bonding? Are you referring to the current between the buildings or within one building?

The electrical wiring will probably not run through the exact same spot in the yard but must also go from one building to the other.

As long as both buildings are supplied by the same electrical connection, this should not be an issue.
