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!

Exactly, if there are different supply lines, you need to be careful.
untergasse4316 Oct 2020 18:33If the supply to both buildings is provided via L1/L2/L3/PEN, differing quality of grounding between the buildings can cause potential differences. These potential differences may then be equalized through the shielding of the network cable, which can be problematic when touching the devices or even damage the equipment. I am not an electrician, just someone who works with devices and thinks things through, but for these reasons, either an equipotential bonding is installed (a thick cable between the buildings) or the connection is made galvanically isolated, i.e., via a short fiber optic link. However, if the second building is simply connected to the main building using a five-core cable, there are generally fewer issues in this regard.

What kind of five-core cable would that be, and what should be considered? Just for planning purposes—I won’t be doing the connections myself.
Best regards
Some time ago, I saw a video from the USA on YouTube where the creator originally networked two adjacent houses (his parents’ and his own family’s). At some point, lightning struck a tree between the houses and caused significant damage to the network components in both buildings. After that, he switched to fiber optic cabling.
Long story short: I would at least consider connecting the two buildings with fiber optic cables and then using a switch inside each building for distribution. Yes, it’s more expensive, especially for trunks with 40 Gbps or more, but it’s also safer.
