They are on PPPoE and yes you can use your own router , as I do. Just ask for the credentials and they'll oblige.

Apparently, they are moving to new modem/routers with the fibre SFP straight into the back of the router.

Says who?

Does that mean that the user will be stuck with their supplied router again?

Depends on whether the box can be reconfigured as a dumb ONT so you can plug your own router in.

That is an NTU "Network Terminating Unit".

A fibre cable is routed from the external box , through the wall and that box provides the connection for the cable to the Adtran.

Why is it needed?

I don't like that idea, I know it is done in some countries on some networks, but having it goes directly to the router, it could get damaged and give consumers less choice on the routers. Bridge mode could be used if it is allowed on the router.

What is a fiber termination unit?
Fiber optic termination units are the connection of fiber or wire to a device, for instance a wall outlet or equipment, which permits for connecting the cable to other cables or devices. The main idea of fiber optic termination is to enable fiber cross connection and light wave signal distribution.

It's more robust than a loose dangly cable which plugs directly into the ONT. If such a dangly cable gets damaged, it may be necessary to pull a whole new outside-to-inside cable.

If the fibre is terminated properly in a fixed socket, then all you need is an SC-SC fibre patch which is easily replaced.

The fibre in the splice box is not spliced on mine, but use a connection of some sort, so if the fibre on the inside do get damaged it is easy to replace. I do wonder how the fibre can get damaged unless someone takes the ONT off the wall, the fibre come into the house and goes directly to the ONT which is virtually next to the hole.
Saying that, I know of someone where the fibre internal is really long and go from the front of the house, though the basement and into a room at the back of the house. So that could be damaged easily. the fibre is pinned to the wall well.

You answered your own question. The ISPs that don't use a wall mounted ONT and have a run from the outside CSP into the home and then straight into a router that is sitting on a desk (thinking of pictures of VM over nexfibre) seem to be sort sighted.

Fibre isn't that delicate, but over the next 20 years it may not be as robust as copper with the vaccumm bumping into it each weekend if its run along the skirting.
