Hi.
One for the Academics out there!
If Germany has an open market for its ONTs, does the rest of Europe?
There's a German law that prevents ISP's/network operators from forcing customers in to using specific CPE.
It only applies in Germany.
Why can't we have the same?
I don't think it's a good idea, particularly with GPON.
A naughty ONT can affect the whole PON.
If your network operator upgrades from GPON to XGS-PON then your ONT/router could become an expensive paperweight.
It isn't the same as using a modem/router on FTTC.
The ONT is the demarcation point. It's where Openreach's network ends and yours begins.
Think of the ONT as a powered master socket.
