OK thanks for thinking of this thread

So by the sounds of it there is some ADTRAN kit in use out there although we don't know if its OLT's, ONT's or both.

Yep it’s not clear from that update unfortunately. I presume it’s at least the OLT.

Likely the Adtran TA401 Micro ONT

You would’ve thought if it’s made it out to wider deployments then it would be noted in the SiN or covered by the press etc. but it’s very quiet.

Assume the Huawei ONT is 1GB port, so I wonder what EE provide with their 1600mbit service?
Anyone know?

A replacement Nokia or Adtran ONT dependant on headend with a 2.5gig ethernet port (engineer visit required)

I recently had a second 900Mbps service installed and they fitted a Nokia 2.5G single port ONT on a separate fibre to the CBT to the existing 1 port 1G Nokia ONT.

Just an update for anyone wondering about whether this is actually possible because a lot of doubt has been cast in various threads (and so I'm adding a note to all the ones that confused me):

It works. I was able to connect to my ISP through Openreach using an SFP ONT I bought online. The original ONT provided by Openreach was a Nokia G-010G-Q so I purchased what seemed to be the closest equivalent, the Nokia G-010S-A (G,S = GigEth,SFP and Q,A is just the manufacturer).

At first when plugging the SFP ONT and fibre in nothing really seemed to be working, however this is obviously expected as I hadn't matched anything from the provided ONT. This was easily fixed by using the information over at https://hack-gpon.org (a great resource documenting configuring ONT hardware) to copy as much of the information on the stickers on the outside of the original ONT (MfrID+SN, HardwareVersion, ICS, Mnemonic, MAC) onto the SFP one. While I was at it I also upgraded to the latest known firmware.

Once all that stuff was copied over it was plain sailing. I was able to use PPPoE (without vlan 101) to authenticate with my ISP (Plusnet), get an IP and route traffic. Everything seems to be extremely stable and I am happy with how things are working. I've not seen any benefit in switching the ONT over to 2.5G mode, however I've left it on anyway as I'm not getting any adverse effect either. It's really nice to just have the fibre from Openreach go straight into my router now.

Obviously, this is all at my own risk and I've kept the old ONT on hand for if problems happen.
