Laying LAN in a purchased prefabricated house - timber frame construction

Or do you think CAT8 would be more sensible nowadays?

There will probably be no home application where you need such a high data throughput. Cat5 would be completely sufficient. Unless you operate a data center.

The 2.5 Gbit ports on NAS and router are becoming more and more common. I would no longer install Cat5 today.

I installed CAT7 in case I ever get to enjoy fiber optics. CAT8 in the private sector probably not.

A CAT7 duplex cable is being installed ...

However, with CAT7, it should be noted that the connectors are different. To take advantage of the benefits of CAT7, a different connector (GG45) is used. With a conventional connector (RJ45), it is "only" CAT6(a) – if I remember correctly. Please feel free to correct me if necessary.

You are right, but of course, you could also use a Cat.8.1 connector, then it is not automatically Cat.8 but better than Cat.6a. ;)

Thank you very much for your answers, I will first install CAT7. I also assume that it will be sufficient for a very long time. So far, 1Gbts is enough for me.

To get back to the actual topic, has anyone noticed anything that doesn't fit? Something that I can solve better or more easily?
