Chorus will be doing the work in the concrete art deco building I live in and it's a tricky path between those two.

Does anyone know if they can use the square conduit often used on surface mounted electrical wiring?

I've seen fibre bent in a really tight radius (talking 2cm diameter) and operate fine for years and years without issue, although it was only over a very short range so any signal strength loss would have been obscured.. I'm not suggesting you should follow that, but it's actually quite tough. How tight a bend radius were you planning on using?

The fibre is so incredibly small and well packed in the cable you will be surprised how tightly it can bend. I think the actual number they use for bend radius is 10 times the diameter of the fibre - which is still rather small.

They will probably just use standard electrical trunking or maybe conduit. Conduit may sound ugly but done correctly can look just as good as trunking.

are you talking about a connection just for you as the only tenent or are there more than one - different cables for multi vs single (size/robustness/bending radius differs) / but in general yes small trunking/capping 16/25mm can be used to house the cableing and not compromise the min-bend-radius / The cost of such capping isnt general part of the free install

It's just for me, one resident/owner, the others will branch off the ETP to other places. I'm told the ETP has (12) fibres installed. There are two other tenants (shops,) neither have signed up yet and given how fast our ADSL2+ is I wonder if they ever will.

Rectangular trunking would be ideal and a $hundred or two to pay for it does not bother me. Which reminds me - has anyone had to pay for "extras" and how is that administered?

What's the diameter of the item(s) inside the conduit/trunking, meaning the fibre(s) with jacket or whatever? There are some wall mouldings to traverse and I think the trucking can be relieved at the back to pass over them provided the contents are small enough.

Thanks for the replies so far!

Ok - your type of ETP is called a FAT or mini-FAT (Fibre Access Terminal) and is like a permanent extension to the Fibre network layed out in the street into or onto the side of what is reffered to as a multi-dwelling unit (MDU), as im sure you are aware this becomes the interconnect point for your's and furture connections from your building.

The Trunking we normaly use is in the top lefthand cnr of this image

The general sizes can be found in this brochure from Marley (we dont always use this brand but its a good example)

The two fibre service cable is approx 6mm in Diameter

Discuss what you want to have installed with the 'Scopper' that will come to look at the requirements for your installation ( this may or may not be the same people that come to look at the installation of the FAT - which is even though may be installed by the same company is handled seperatley)

Awesome, thanks, those pics are exactly what I needed.

Both Chorus and Downer visited some weeks ago to scope out the install and we pretty much have agreed on a route. However, the devil is always in the details and when they arrive this coming week I would like to have a good idea of the materials available so I don't compromise on appearance where I don't need to.

cheers!

So Chorus have finished the installation today in my building. It took 4.5 hours and they did a tidy job. For the most part it appears they can bend the fibre at 90 degrees within the space of the 16mm ducting ("capping" they called it.) In other places they used a short length of flexible black corrugated tubing.

Question, my speed (from Telecom) doesn't even break 10 Mbps. Is that likely to improve?

That looks suspiciously close to 10Mbps, I'd call up and ask if it's set up correctly. It could also be a network card, router, etc on your network that's limited to 10Mbps for some reason - check that first. Try another speed test server, if you're with Telecom use their speed test system not speedtest.net.

I checked cables and everything I could think of and the only item I just found is that the log-in info was not filled out for the Fibre WAN interface, however filling in that info and restarting the router did not change anything. The techs had told me before they left that it is the exact same login as I had for ADSL.

Meanwhile over the 5 hours since install and leading up to that it's been slowly increasing, now at 16 Mbps (telecom speed test,) about what my ADSL2+ was producing.

Images attached of setup (username/pw whited out) The lowest entry says Mode: Full

EDIT: When up to 17.8 Mbps just while writing this :) Can hardly wait to test it tomorrow morning.

Is this supposed to be a 30/10 install ?

If so this is no-way correct and you should escalate to telecom now and not wait to see if it will speed up

OK, it's up to 24 this evening, 26 hours after install. I'll give it though the weekend, something must be changing but no idea what.
Yes, it's a 30/10 install.

Not much change anymore:

Discovered another wiring cock-up, this is where the ceiling cavity cover goes. They have run the cable too close to where the cover fits in its frame.

Well, in case anyone is interested after my download dropped to 3 on Tuesday, yes THREE Mbps, and just before I wrote a snotty email to Telecom, I investigated more thoroughly and found the problem appeared to be a utility (QuickStream) that AMD installed automatically as part of my Catalyst chipset/GPU driver that "manages" bandwidth to favour video. It appeared to arbitrarily strangle the Speedtest utility.

All fixed and I'm up to a consistent 29 Mbps now.
