There is nothing thinner than 0.3mm in the Openreach network.

I'm also struggling to see how the drop wire to your house is aluminium and is 0.3mm?

Thinnest drop wire in use is 0.5mm copper (CW1378), drop wire 6, 8 etc were even thicker (but not twisted and one of them being copper covered steel).

Drop wire 11 and 15 (used to be called 10 and 14 before the changed 10 to one pair and renamed them both by an extra 1) are 0.5mm copper and have been used more recently.

BT were deploying .0.32 ali in late 1970s. By coincidence thats when the houses around me were built.

I have to say, I was quite impressed by the results there. I had expected the range of "superfast" to be extended some 200-300 metres, but 1600 metres would be more than I really expected.

And, as you say, interesting implications for BDUK - but equally interesting consequences for the extender technology, like FTTRN. It might alter the planning decisions about where these nodes should go.

There is anecdotal evidence that the rollout seems to have been Huawei-heavy recently. With no visible progress with ECI's vectoring, this might be a reason why.

Yes that's interesting, I've noticed the same. It seems to be mostly Huawei cabs going in at the moment, even in areas where the headend is ECI and all previous cabs have been ECI. It doesn't seem to be a problem mixing cabinet vendors in areas now.

The Huawei cabs will be connected to a Huawei headend at the exchange.

Not drop wire though......

in use

I think that is the problem in your post. It might be the thinnest that would be used in new or replacement installations, but that doesn't tell you anything about any individual case of the 28 million existing lines.

Presumably the rules were different 50 years ago.

Cables were thicker all those years ago, just not twisted.
