Welcome.....maybe you should have saved your very first post for something that was worthy.

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.

I just dislike having a) A single point of failure that I don't have a replacement for sitting ready to use

I once did a contract at a major online bank. They seemed to have a similar view to yours, so next door there was a spare facility, identical to the one where I was working.

I never saw inside, but I was told that it was all complete and set up for a failover.

To me, it seemed daft. I'd have had the spare 50 miles away, not 150 metres.

But I guess it was better than nothing.

If your broadband goes down, can't you just move to your spare house?

Great to hear it worked.

I think the main issue with changing or messing about with the ONT is that the fibre isn't just our connection but connected together with up to 30 other properties, so a new ONT, if something wasn't right, could bring down the connection or cause intermittent problems for up to 30 other properties. GPON is a bit like a party line of old, only this time shared with 30 or so properties. This will be why Openreach is only wanting its own approved ONTs connected.

I agree. One of the side effects of ADSL is that we were all on our knees peering into an NTE and tweaking and tweaking because there was likely something to be gained from so doing. And ISPs were doing their bit, peering from their side beyond the NTE into the router. And some were locking down our routers and evend dictating how we configured our LANs.

With fibre we now have something of a truce. The ONT is not ours and the router is [should be] ours. It should be a truce. The ethernet between the ONT and the router should be noman's land. We should leave the ONT alone, really we should, because if we don't, the ISP's will come and take over our routers again. Much though I would want to play with the ONT, there is nothing I expect to be able to do to improve anything and besides that, I am happy that I am getting the spec I pay for and I don't have an ISP inside my router. That's how I want it and I want it to stay that way.

Unless you are on BT and need their version of digital voice when you have to use the BT hub and they have full access to that.... Not quite there with your utopia yet.

I actually think that this will ultimately lead to the death of passive networks in favour of point to point. All it would take is for an attacker to get control of a small percentage of ONTs in a network and they can bring all of it down. That makes ONTs a tempting target for attack.

I give PONs 20-30 years before a security incident makes them non-preferred amongst most suppliers.

I think only Virgin Media have this right where their router handles the coax to Ethernet and also voice (where purchased), but can be put in "modem mode" and then the public IP is available to your own router but voice still works! Everyone else I know whom wants to use their own router has to sacrifice any voice service, BT Retail's Digital Voice, Sky's Sky Talk, or Vodafone's voice, etc.

Long term I wonder what the outcome will be, either voice will be hardly purchased, or people will tolerate using the ISP router more than they do today. Neither is good. A "modem" or "bridge" mode in the ISP routers would be one step forward.

(ONT not mentioned as this issue affects FTTC, ADSL, and FTTP users).

Good reason to ditch BT. In the world of VoIP, they are effectively non standards compliant.

Not necessarily a problem for DV. I have Zen via CityFibre (probably no different with OR) and their supplied 7530 AX router does have a FON port for connecting an analogue phone to Zen's DV. However it's perfectly possible to set up Zen DV as any other VoIP provider, to use an IP phone connected to the router via Ethernet.

If you have the appropriate connection data this may also work with other DVs.
