You can buy an XGS-PON module from AVM for 70 EUR.

Thanks, an AON and GPON module is probably included with Digitec. Question:
a) Is an XG-PON module also included or does one have to purchase this separately?
b) if you have to purchase it separately, where do you get it (e.g. from Digitec)?
c) Which provider do you have?

Yes and no problems during installation
