That's what houses built in the ~'30's gets you I guess.

Here's a pic of my CityFibre CSP showing the CF microduct emerging from the BT duct:

They’ve brought that out from the duct below ground level, not exactly smart practice. Allowing egress of dirt and muck to the duct, and ruin it for all. Also they’ve made a pinch point where the tubing is coming up through the clart.

The duct terminates where it did when it was installed in 1988, when a few inches of it was full of muck, which never caused any problems.
I've just been out and had a look at it, though. It is plugged with plastic, bubble wrap or similar, I didn't take it out to look, so it's much better than it was under the BT regimen. And who else is going to be affected by any rubbish that gets in the duct between my house and the BT chamber? It, and others nearby, is more likely to be damaged by the roots from the rowan planted near the chamber.

Can't see any sign of any alleged pinch point.

OK, the foam bung is in place. Good.

I didn’t say it would affect anyone else, but if your duct got blocked, that wouldn’t be ideal. Less chance if the bung is in situ.

As for the suggested pinch point .. once out above the bung there is, or ought to be, a flared base bringing the flat rectangular connector bend 101 together. Your picture would seem to show the fibre appearing from below ground level outside of this housing. That’s the bit I’d cast aspersions on.

Any way, not here to argue the toss. If you are happy with your install, then that’s good.

in fact they don’t use them anymore , the duct they provide when an order is received goes from the jointbox to the house wall .

At the moment we have a hose pipe tubing that literally provides ducting from the BT joint box that just goes underground just past the front garden brick wall, the tubing stops there as soon as it emerges above ground (front of garden). From here on the phone line runs along the side wall (shared with the neighbour) along to the CSP on the house wall.

Will BT follow this same approach for the fibre wire or will they actually install ducting all the way to the house wall? If so that would mean digging the length of the front garden to lay the ducting which will involve quite a bit of digging.

BT won’t do anything, presumably you mean Openreach ,
Providing duct the entire way from the jointbox to the house wall is the correct method, and really the best method, but until an order is made and the grounds work people turn up it’s impossible to say if this is mandatory , they may well negotiate and provide whatever is your preference, if it’s a realistic proposition then will probably agree , so if your preference was to copy the existing copper route and have duct only to the garden wall and then cable on the garden wall to the house wall ( to avoid some excavation and reinstatement ) they may well agree ( it’s less work for them )

COW , cable on wall is perfectly acceptable , after all if the duct entry were at the front of the property but the ONT was required at the rear , they would look to run the cable on the wall from front to rear of the property , so no real difference providing cable on a dividing wall or house wall , the only potential issue is if the wall between you and your neighbour at some point was to be demolished, then the cable would obviously need to be moved underground at your expense, whereas at installation it would be ‘free’

I actually wouldn't mind them digging the whole way to get the ducting in as it would future proof things for any future wires!

But good to know thanks!

We're seeing this almost exclusively in the UG plant being installed for the R100 rural build up in Scotland, and quite a bit of it where they've installed new ducting for DIG areas.

1" 'microduct' that was used for a period of time back in probably the 70s or 80s (I think). It can be very hit or miss as to whether it's useable - we've had some where the drop cable has gone through with no issues and others where we've had to use a ton of duct lube to even get the rods through. Usually capped with a rubber gas seal at the premises end as well.

All the DIG estates in my city are microtrenched with tobys (openreach)
