As part of the Casa de Cowboy rebuild, which is a constant rain of pleasant surprises as we discover each new cowboy thing done to it, we're going to set things up to run fibre into the networking cabinet. We've got the required green conduit run up to the house walls to which we'll add a sweep bend before we bring it up the wall. The best place to put the ETP would be at the top of the concrete basement wall above the waterproofing, from which the fibre can run (externally) straight down into the ground and (internally) straight across the currently-open between-floors space into the network cabinet. I've read various web pages that cover this but they're a bit unclear about:

- Can I install the ETP so it's where I want it, not where some Chorus technician might put it, specifically so it doesn't require penetrating waterproofing on the concrete wall?

- If it's a case of ETP -> HCC, what's the bend radius on that? No way I can put a 900mm sweep bend in to take it into the house from the ETP.

From this thread it looks like my best bet is to try and score some HCC during the scoping visit to put in myself, but I'm not sure if I can do a scoping visit without also signing up for an install later, due to ongoing building work I don't know when "later" could be.

You can get OptiCat5e from various electrical wholesalers. I am not sure if they will sell you it by the meter though. Bend radii don't really need to be any better than being nice to Cat6; ~100mm is more than enough.

If you make things easy for Chorus to put it where you want it (conduit coming out of the ground, conduit/cable coming out of the wall), they will put it there as long as it's not totally against the rules. Avoid the gas meter, ETP outside the building etc.

Hi just put in standard 20 or 25mm grey conduit from the Etp to the data cabinet with a draw wire and insure large swept bends or use flexi to achieve same.

Chorus installer will supply OptiCat5 and use your draw wire, easy.

As for the 900mm chorus swept bend, that's the radius segment, the radius will be 200-300 so not as large as you imagine.

Chorus wouldn't give me the ETP ahead of time to mock up the mount to fit on the weather boards. The ETP was 150mm high and it wouldnt fit on one weatherboard so i wanted it blocked so it wouldnt be hang over nothing.

I measured off the neighbors ETP and hoped chorus were still using the same one.

I ran my own green conduit from the pole to where the ETP was and made up my own grey 20mm conduit from where it came out of the ground to where the ETP was. I also ran some 20mm flex from the network cabinet to where the ETP was (about .5m, it was almost back to back)

ETP should be on the outside of the house but chorus also states "we strongly recommend not having the ETP in the network cabinet" so you could do it that way if you wanted. i decided againt doing it that way as the conduit from the pole came up outside the foundation.

Personally i would do everything before chorus turns up, and just point to where you want the ETP and ONT, and have all the conduit etc run. makes their job easier and you will get what you want.

Thanks! So just one question, based on this high-tech diagram:

At the point marked "to ONT" what's the bend radius there? And I realise the diagram isn't completely true to form, the cable exits the ETP at the bottom so I'll offset the grey conduit about 20cm to the left(?) to accommodate it running up the side of the ETP.

Hi the cable can deal with 7mm bend radius if u sheathed, so a standard swept 20mm grey bend is fine just do t glue it.

one of those should be fine for it. just put a draw wire in the conduit when you finish.

They might prefer to mount the FTP higher so the cable can come out the back of the box straight into the house. I think the cable wants to exit down instead of up, but maybe the builder can create a flat place to mount it? You will have to ensure they put the ONT in the required location, and give enough space above it so you can see the lights. No idea why the lights all point upwards so you can't actually see them inside a cabinet.

Time to find a new industry!

On this subject, I keep seeing the option of "fibre sockets" being talked about for fibre installation setups. What are they talking about?

Interesting. I didnt know this was an option for residential connections. I hope it's true.

I see it as no different to socket in the wall, except fibre in the back, into which you can plug a fibre pig tail, inside of a hole in your floor where the fibre comes up, and the ont having to be fixed in place.

Problem is, fibre isnt really supposed to bend like copper, and the change of polluting the connection is extremely high if you plug/unplug like its an electrical connector.

Just guessing, but maybe it's a reference to ITPs found in some Enable installations? They reference them here.

It being plural and are connected to the ONT" makes me think they're just installing hardwired ethernet jacks, via your fibre connection. Possibly for having 2x internet connections in different parts of the same property, off the same ONT?
