Containment for fibre... Improvised.

[FuerteStu]

So my new fibre line install is going to be 'on a suitable outside wall at the front'.. 

 

About 5 metres from my telecoms area with my switch panel. I've spoken to a guy who surveys the install (virgin, not Openreach) and they've said they don't mind a short containment run as long as it's in place in advance with a draw wire. 

 

I said I'd do it in 20mm conduit, but I noticed I've got 8 metres of 15 pex Speedfit sitting there doing nothing.. Surely that's a better option right? Smoother interior, no couplers needed? 

 

Anyone know of a reason why not? 

 

It's going up a boxed in riser that takes my outside tap feed, through 4 metres of loft and down into the IT cupboard.

As long as you pull long radius bends then defo a winner. I’ve used 16mm pert-al UFH pipe to send temp sensors down, buried in the screed etc, and works a treat.

 

If you can get a fish wire up it, then the fibre will zoom through.

Should be fine. Just bear in mind that if it is fibre, it may be a pre-terminated cable of a particular length, so the inside diameter of your PEX needs to be sufficient to take the connector, and the bend radius you employ needs to be appropriate to the connector length too.

 

I installed 20mm flexible conduit from the external box (City Fibre in my case) to my internal comms cupboard and we just fished the cable through when they did the install. No issues.

Awesome. 

 

Got a draw wire down the length of it that's got a 10mm diameter head with ease. 

 

I'll sweep the bend through the outside wall, just chase a section upwards from the penetration. 

 

I think this will work way better than 20mm conduit to be honest, as it's a continuous run.
