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?
