You cannot just buy any SFP module and have it work. Most ISPs deploy a “special” (at least compared to normal point to point fiber links) that lets them serve multiple customers out of one port in their office. This is called a Passive Optical Network and requires specialized modules on both ends. There are ways to make a specific SFP work as an ONT and by cloning certain identifiers from the ONT to make the ISP think their box is still there.
This is a lot of effort and from my research, could stop working randomly in some cases.












I mean, it was a book wrote for teenagers, it definitely went more for the YA title than “hugely impactful peace of thought provoking literature” but the point was, it at least had some kind of backbone compared to the others that seemed to try to ride off of the Hunger Games.
