It is installed with no screws, you just need to pull it out (the module has a tiny foldable handle for that) and slide it into the SFP slot of the TP Link.
Cheers

Is the SFP module located in a slot in the router base?

I've just been connected today and the supplied router has an empty hole there so it doesn't look like I have a module to remove!

Like many here I'm horrified to find I can't simply use my existing mesh devices to replace the Adtran router. It surely isn't good practice to provide a broadband service tied to a specific device!

For many ISPs it is the preferred route as it allows them to have a known device on the end of the line for doing troubleshooting if there are any issues. Many ISPs will only provide support if you are using their router and some make it very difficult to use your own router.

Yes, the SFP slot is at the bottom of the router - I am assuming you have been provided with the Adtran 854v6.

If you have been connected you should have the SFP module inserted in the slot and the fibre plugged into it.

Many thanks for the replies.
Yes, I do have the Adtran 854v6 router but the slot at the bottom is empty and the connection works fine. Does that mean I must have an ethernet ONT device? If that is the case should I be able to set up my existing ASUS mesh system to replace the Adtran one?
I've read above about needing the VLAN id but the routing page on my Adtran dashboard doesn't say WAN:nn anywhere so I'd love to know if there is another way of locating it?

If you have an ONT, then you should have an ethernet cable between the ONT and the WAN port of the Adtran.
If that is the case, you are correct as you should be able to simply replace the Adtran with your own router.

I can't check right now but I am pretty sure the WAN.nn string was in a table towards the bottom of the routing page. I was accessing it using my phone and I had to scroll the table horizontally to show it.
Have a go and let me know if you can find it - I can try and help more later when home if you struggle with it.

Yes, we do have an ethernet cable from the ONT to the router so it is good to know that there might be a solution!

I've searched the routing page and downloaded a copy but can't find WAN.nn or similar. Maybe the firmware has changed. I don't seem to be able to insert the file here but will paste a copy of it below.
Thanks again

On the basis that I am not the person best placed to answer your question as I only have a fairly basic understanding of networking:
- maybe the ONT is managed and contains the VLAN ID?
- have you tried connecting your own router or a laptop to the ONT without specifying a VLAN ID ?

I'm in the same boat as David Hughes. AdTran installed today with BeFibre, but they used a Nokia ONT with a copper ethernet connection to the WAN port of the ADTran - no fibre direct to the SFP port of the router.

If I plug the ONT ethernet cable in to my laptop. I just get a 169. address
If I set the VLAN ID of my laptop NIC to VLAN 10, still get a 169 address

If I plug it back in to the ADTran, internet works great but means I'm currently double-natted.

Could they be using PPPoE on the ADTran to dial out via the ONT?

Have you tried spoofing the MAC of the Adtran?
