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?

I'm in the US, had Verizon at the time. Switched from 750Mb to 1.5Gb and they had to swap in a new ONT because the switch side in the old one capped at 1gig. New ONT was up to 5. I have no idea where you'd check the specs for it. Mine is mounted and the info sticker is probably on the side against the wall.
