Ooh nice to actually see what's inside. I drove past when they were installing, but there were quite a few working in front and it's a busy mini roundabout, so couldn't stop.

Yes it is Haverfordwest. I think that exchange serves all the towns close-by that are getting FTTP.

Plus, I know BT are installing FTTP in town as confirmed by Openreach When and Where.. On top of that, there is no need for VDSL expansion, as nothing new has been built nearby and there are several vacant house in my estate, which would free up capacity if needed.

I would guess at Haverfordwest. The SHE's serve 2 purposes. They extend the distance from the HE exchange , and they also reduce the number of fibres . Many are used purely for the latter which is why some are located relaitively close to HE exchanges in urban areas to save on new fibre spines.

How much autonomy do these SHEs typically have in the event of a power outage?

Presumably the OLTs sitting inside a HE exchange building are happy to chug away until the diesel genset supply runs dry.

They will run off the DSLAM batteries, however long they last, if fitted!

Thanks. Thought that was the case.

There ya go …. thank you.

@witchunt do you have a view on numbers of SHE that Openreach have deployed to date? Even just ballpark numbers.

TIA

I can see the financial attraction for Openreach but in that configuration it does defeat the point of a passive network as theres still going to be unnecessary kit humming on the corner of streets

it defeats it being purely passive but it has some huge savings and speed of deployment, especially with pole deployment of last mile fibre ..

It could even be used to deploy fttp and then at a later date remove it to provide a full passive spine.
