Hello,
is it possible to use a GPeR-repeater with one device POE out on the one side, and the other device with “nothing”, I mean without any POE?
Al the diagram I see, they use on the one site POE out and on the other side POE in…

Yes, you can remove jumpers on PoE-out side and then it won’t pass PoE further.
But there is a note, that it won’t work if 802.3af/at is used - the power source device won’t power the GPeR alone.

Great, thanks. All the information was there

Do you know guys why GPeR can’t be powered by 802.3af/at itself? I’d like to extend the link between two switches, however in that situation it isn’t possible to use GPeR.
You could use RBGPOE passive injector from one side to power GPeR … I guess.
