Except that when these type of cables and non ducted underground feeds were being installed it was to service a very different industry ........

When I started twenty years ago a few were having 2nd lines installed for dial up.

Still see direct in ground cables and joints working just fine all these years later.

Hindsight is 20/20 vision.

We have this outside our house on the pavement and there is some more serving other houses on the road. Would this mean they're non ducted feeds to my house? What is the purpose of these particular fairly small inspection chambers?

There's no overhead poles around it's all underground. House built 1979/1980 but always wondered what kind of ducting.

Which is exactly why I didn't mention broadband or FTTP etc, because they didn't exist back then. But line faults, corrosion and the likes did, and surely it must have made more sense to install ducts than not, especially for system that would need maintaining, and cables replacing from time to time. Perhaps digging up roads was a cheap as chips back then.

I bet you see plenty of cables that need to be dug up to gain access to, plenty of old cables which are well past it being patched, because they can't pull a section and replace it without digging up the entire road. I know because OR engineers have told me, more than once - patch, patch and patch again

It's a JB23 (joint box) and will contain either a joint or the DP (another joint basically). It's pretty likely that there is no ducting and there's armoured cable laid straight in the ground.

I see, thank you for explaining.

New build in Derry has FTTP, there's no other trace of FTTP deployed in the City, but I guess it's down to the developers and Openreach

All showing native FTTP (the houses that are ready that is)
