The AON version worked perfectly with my Swisscom connection. Unfortunately, the Swisscom subsidiary Wingo was not prepared to set up an AON connection for me. I didn't want to spend money again on a PON version of the FB 5530, so now I'm with another provider.

The Fritz 5530 can replace the Wingo router in the xgs pon network. I have it running myself. But for this you need the xgs pon edition, as you write yourself. This is the AON Edition.

If you have the 5530 with xgs pon SFP, it works. But you have to pair the box. To do this, you need the NSN number of your connection, which you can only find out by calling the hotline. Further information can be found in the SC Community Forum under 5530 xgs. With the box offered here, this only works in the AON network.

You can also order additional SFP modules via https://avm.de/service.... I was also running AON and have now ordered an XGS-PON module for the new subscription. Unfortunately, I can't get it to work.
