I'm getting a sparkie to prep some ducting between where our ETP will be and the ONT. I'm only doing this because the chorus tech said they only provide 5 meters of ducting and I need it to run about twice that. Is there a minimum spec/diameter required for this, or will any exterior rated 10mm duct do the trick?

Cheers

*looks at bare cable running along wall*

"Ducting", you say?

No ducting in my install. It is nailed/clipped to the beams under the house. Goes from front corner (nearest road) ETP to a cupboard in the middle of the house (runs under floor then up into cupboard).

They don't usually use ducting between ETP and ONT. Just bare wire underfloor or through roof. He may have meant trunking. They only provide 5m of trunking. That's what they use to externally mount the cable on an internal wall.

use 20mm conduit and SOFT BENDS, then throw a good draw wire in.

this will make the installer very happy.

the key work here is SOFT BENDS not sharp 90 bends.

As per other responses, suspect you meant indoor trunking rather than ducting.

However - if you are planning on doing some serious renovations to prepare for the arrival of fibre and you will install a distributor cabinet in the internal wall to house the ONT - you need a duct from the ETP to the home distributor location.

There are really two options, both as per the industry agreed specification recently re-released by the TCF (source: http://www.tcf.org.nz/library/85f5318d-fc71-409f-a04d-48ff414107f7.cmr):

1. Install conduit from the ETP to the ONT - 20mm ducting with no more than two swept bends – not elbows – would be preferred. See section 27.8.

2. Install fibre from the ETP to the planned site of the ONT - Source Prysmian OptiC@t composite cable (which has both copper and fibre inside) and install this from the ETP location to where you want the ONT, leaving at least 1.5m slack at each end. Ensure the cable is not damaged during installation, otherwise we cannot use it. See section 32.1.2.

Crap.

I've been away and just seen these responses. So the problem is were my current copper connections comes into my house is on the bottom floor of a concrete based house. My understanding is that the fibre to the property will be to this (the ETP). I want to setup a patch panel in the garage which is about 10-12 meters around the corner. I can't run that cable through the roof or under the house so figured I could run it externally along the base of the house (which is approx 5-10cm off the ground and about 1cm in from the cladding. This would however mean it would require an elbow bend...

The red is the ETP location and the blue is where I hope for the ONT to go. The red line being the ducting

The other option could be to run it through a sofit but I have no idea how you'd make it go around the corner...

You could do it like this, with 20mm conduit, but for the corner you would need to use a 90 degree swept bend, not an elbow. Something like this:

Run a draw wire through it as you install the duct and you're good to go!

Probably a silly suggestion (not my area of expertise), but couldn't you just get the two straight runs ready with draw wires. Run the cable through the horizontal, then feed through the bend by hand, then start it running through the vertical? Not sure how long your runs are, but you'd need to leave off a few of the clamps towards the bend to give enough flex.

Why bother using a sweep bend? The people contracted to install UFB sure as hell don't.
