Optical Network Terminal (ONT) information (lemmy.zip)

Here’s a question that I can’t seem to find more info on the internet on, so I’m turning to Lemmy. Does anyone have a better understanding of the specifications around an ONT. I know it basically converts the incoming fiber (usually single mode single fiber) to an RJ45 jack for copper runs but that’s the part I’m curious about:

does it convert it to use standard Ethernet frames or is it a proprietary protocol?
if Ethernet, is the port speed 1G, 10G, etc or based on the hardware?
if it’s a proprietary protocol, what does it use?

I recently got a new router and noticed it’s capable of 5Gbps on one port, but that got me thinking about the ONT and if I were to upgrade my service would i also need the ONT replaced too?

The ones I've seen use standard Ethernet frames.

Supported port speeds would depend on each ONT's design. If you upgrade your service to a speed that your current ONT can't handle, then you would need a different ONT, of course.
