If I recall, for something like GPON or XGS-PON, you end up having to clone the various attributes of the original for it to work properly. This typically includes serial number, hardware id, firmware identifiers, etc.

For most it is just serial number. The 8311 folks have scripts that will fully automate the cloning for most common devices. This is not like a "break open your hardware and attach wires" type thing.

There are some ISPs issuing and verifying certs for GPON, which are more annoying to extract. I'm not aware of anyone (even those same ISPs) doing it for XGS-PON. It seems they all decided maintainimg their own CA infrastructure for millions of customers was not worth it ;)

Question out of curiosity. I once swapped a TPLink media converter between two homes, both using the same ISP, to debug internet issues and to see if that would improve the situation. Did I do something incredibly illegal? And did my ISP get confused seeing my media converter on the other side of town?

		This wouldn't be criminally illegal anywhere unless done with some sort of fraudulent intent, but maybe in some places the ISP could make you swap them back.

		Illegal? No, at least not in any sane jurisdiction. It's no different than moving a SIM card between phones. Confused? Maybe but probably not. It depends on how they track things. An ISP I had in the past tagged subscriber accounts on the OLT side.
