I seem to remember that a long time ago, a single 2.5Gbit fibre was split across 32-64-128 households. The GPON’s job was thus to only decrypt the traffic meant for your connection.

It may be wrong information, or it may be completed outdated and irrelevant, but I remember that this was a reason why it was difficult to use your own ONT.

But seeing as the ONT is just a reframing/medium converter, I’m not sure I’d care enough, as long as the one provided by the ISP is reliable and performs well (those old black Alcatel ones were terrible).
