Question about WL Router GT-AXE16000 AiMesh - 594313

Yep, I would wait if possible as Asus has already shown 2 new routers at Computex 2023 (RT-BE96U & GT-BE98).
If you still want to pull the GT-AXE16000 and FTTH P2P would be available at your place,
you can buy a 10Gbit (SFP+) media converter and order the matching SFP+ transceiver from Init7.
Delock SFP+ to RJ45 media converter

However, I would currently advise against this, as you will incur additional costs of over 200.- :/

Yep, you need it and it's hard to find for 10gbit. If you have a p2mp connection, init7 has a converter. They can also give you information. Otherwise I would buy a router with sfp+ connection from ubiquiti for example.
