As someone shopping around for a FTTH offering (to get out of my current DOCSIS plan) how can I figure out which routers are compatible with the ISP's GPON?

I've had phone calls with them and the support/sales reps have no idea. They provide their own router+AP box that takes the fiber and spits out WiFi and Ethernet, but how would I go about replacing that? Their hardware is obsolete, insecure, outdated and just all-around poor! I know I could set it to bridge and place my own router in between, but I'd love to just replace their box instead.

As far as I could figure out on my own, the best bet would be getting a EdgeRouter X SFP and then plugging in a compatible SFP module. Is that right? How would one figure out which SFP module to buy?

On top of all that: do ISPs run proprietary handshake stuff on top of it, where even if the physical connection is correct, the ISP refuses working with your box? or is it just like the old ADSL days when all you needed was just a PPPoE stack?



At my ISP we offer XGSPON/GPON and we have to use our equipment for the ONT (In our case Adtran). We have adtran specific handshake stuff that we have to manage. Your ISP might offer to just use their ONT and put it in bridged mode so you can use your own router/ap.

There are ONT SFPs that contain everything you need to connect back to the OLT. Maybe you can ask your ISP if that is supported?
