Question about FRITZ! Box 5690 Pro

curious if you (or someone else) ended up using it successfully with netplus ?

The router in question is compatible with AON and GPON fibre optic lines thanks to its SFP port, which makes it potentially usable on the netplus fibre optic network in Switzerland, provided that netplus uses these standards. However, it is advisable to check with netplus to confirm their specific compatibility.
