So that I can take a second fibre service later, onto a second ONT, without having to re-pull through the underground ducts and the attic.

I thought you could run four fibre services on one cable - you just get the ONT changed to a 4 port model?

I think by getting a second connectorised cable pulled through ready candlerb has got options, either a 4 port ONT (if available) using the existing fibre or a second 1 port ONT connected to the second fibre.

The thing I'm most impressed with is the Openreach engineer was prepared to pull the second connectorised cable through.

It wasn't connectorised - just cut. If and when the second ONT goes in, it will still need pigtails splicing at each end.

Considering how Openreach are, I am surprised they even pulled in a second cable.

But you said in your other post

There's no external splice box: the cables were pulled in one piece from the pavement chamber to the ONT. In the pavement chamber there's a 4-port CBT.

I believe connectorised means the fibre cable from the property has a pre-connected connector at the CBT end not the ONT end, are you saying the connector on fibre cable at the CBT end in the underground chamber was added manually as that would seem strange.

I didn't see what went on in the chamber end. If what you describe is standard practice (i.e. the cable is pre-connectorised at one end only) then I expect you're right.

The drums of cable seemed pretty large to me.

I did see that the cable was pulled *towards* the ONT location, and it was not connectorised as it emerged at that end. So if it was pre-connectorised at the other end, the drum would have had to be completely unspooled and all the slack pulled through, before cutting. That could have happened - I only checked in occasionally to deliver cups of tea

Does anyone have a picture of a CBT mounted in an underground chamber?

Nothing unusual about having multiple fibres to a property. I had 4 fibre strands blown to my external CSP, with 3 kept as spares:

So in a connectorised (newer) install I don't see why Openreach would refuse a second fibre cable (since each connectorised link only has 1 fibre strand) if you gave them a valid reason, eg provisioning of additional FTTP services in future.
