Hope Zarjaz or Wicthunt may know the answer to this.
I noticed a street with 3 wooden poles having fibre boxes on the top, but the one metal hollow pole has no sign of anything. Does anyone know how OR provide FTTP from the metal poles?
Is there a FTTP box that fits inside of are these going to be an issue.
Road is in Whitchurch Cardiff but the FTTP is not yet live on this street ( only one Postcode) CF14 1BH

I believe there is a solution for hollow poles involving extending the fibres into the base of the pole that leaves them in a loose bundle ready for the installer to plug into.

If this is connectorised you�re talking about, what happens with to �stress point� where
the cable goes over the shoulder at the top ??

That was going to be my follow-up question if there was a solution at the base as the cables take a lot of tension on that shoulder and it's quite a tight bend.
I wondered if the was an issue and that is why the street hasn't gone live, couple of other streets also not live have hollow poles.

You can get fibre optic cable with very low bend radius these days, down to 5mm for single mode fibre.

I don�t believe the bend radius would be an issue, there�s a bell mouth affair on the top, and was taught that these fibres would take a radius of a fifty pence piece with no loss.
It was that with a secure anchor at either end and this shoulder in the middle there was a chance of repeated stretching on the shoulder.
These hollow poles can and do move a little at the top.

I have seen them move quite a lot when we have had a proper gale and the cables seem tighter than on a wooden pole where they droop a bit.

Yep, and with a solid anchor either end the stress point will be on the shoulder at the top of the pole I suspect.
A few years back when it rained, froze then snowed over night, the additional weight on the dropwires actual ripped the dropwire anchoring rings out of a couple of hollow poles in Reading.

Not an issue with the Corning EZ Bend connectorised cable Openreach has gone for. I�ve had it tied in a knot and repeatedly whacked with a hammer and still had the same amount of light pass through. That�s if we are talking connrctorised. Obviously wit the legacy stuff that�s completely different.
