New Build with Older ONT

Hi all
Seen a new build apartment that was completed last year that I may be moving to next month and surprisingly it had the old style ONT with Battery Backup unit.
Will this affect my ability to upgrade to a new 1G Down and 1G Upload product once they start to roll it out?

If the development took a few years to complete, then its possible the developer obtained some of the last BBU style ONTs from Openreach. I have one of those with a 1+1 Huawei ONT. Not long after my service commenced in 2019 they were officially retired.

In any event they wont support symmetric 1G/1G service. No Opnearch ONT supports this as Openreach FTTP network is purely GPON based, not symmetric and only offer up to 1000/220 service.

If and when Openreach decide to upgrade their network to XGS-PON only then will symmetric services be offered - and a replacement ONT would be needed for any properties in an enabled exchange erea - again not that there is currently any known timescale or any announcements on that, bedside a limited trial which completed a while ago.

I suspect they might skip XGS-PON all together and move to the 25Gbps PON standard going through the standards process right now. Would give them the option of a very lightly contended symmetric 1Gbps or more likely a slightly more contended 2.5Gbps symmetric option.

And only those properties taking XGS-PON based services need a replacement ONT. GPON and XGS-PON (and 25G for that matter) can coexist happily on the same fibre and splitter, so users who are served sufficiently by GPON will not be affected.

I don't expect GPON to be retired for a very long time, so long as the vast majority of users are on baseline 40/10 or 80/20 products.

Ah makes sense.

Agreed and if Openreach can figure out the least disruptive way to migrate those on the speed constrained ECI based OLT estate, is likely more of an imperative.

Indeed all possible but very much crystal ball stuff and dependant on mass volume price points. At some stage XGS-PON cards and ONTs will hit the same price point as GPON which is now dirt cheap.

The complimentary GPON, XGS-PON family (ITU-T G.984/G.9807 based) standard for 50G-PON is currently going through ITU ratification. When that’s done Nokia will no doubt show that off to their customers as the 2.5 -> 10 -> 50 upgrade path.

Then Nokia were lab testing single wavelength 100G-PON with Vodafone back in February...

Did it have the battery pack installed, or was it just a larger Huawei ONT in the case with space for the battery pack?

It would seem to say that the BBU was already there. It might even be an elusive Huwawei four port ONT

Didn't get time to open it but the case was the standard cases with space for both. You're right could be just older ONT without BBU as they no longer provide digital voice like that.
