coffeebaron: - Congratulations, you have reached Mav's home! I am proud to be the Ops Manager for NZ's best VoIP service, and would like to tell you about one of our advanced VFX calling features; it's called "selective call acceptance", and guess what - your call has NOT been accepted. But fear not, to reward you for trying, you will now be placed on hold and for your listening pleasure - "Celine Deon - theme song from Titantic" on continuous loop in full G722 HD quality voice!"

LOL!

ADSL
VDSL
Fibre


All with the same ISP? Smile

So does this mean we are close to seeing VDSL & UFB offered by WxC? :)




Chorus has spent $1.4 billion on making their xDSL broadband network faster and even more now as they are upgrading their rural Conklins. If your still stuck on ADSL or VDSL, why not spend $195 on a master filter install to make sure you are getting the most out of your connection?

So each customer has a fibre (or two) joined to a fibre on the blue 'trunk' cable which goes back to the cabinet. Is this GPON with an optical splitter, if so where is it? Is the cabinet passive with optical splitters only, no fibre switches in there?

Very fast "DSL" connetion - "test the quality of your DSL connection" :)

You said that you're in Glenfield, which is where I am too. However when I look at the Chorus Network Upgrade Map at http://www.chorus.co.nz/maps they haven't scheduled a date for when my street will get fibre. On their map if I zoom out I can see that it looks like all of Glenfield isn't getting fibre in Year 1, and only some of Glenfield gets it in Year 2. I'm in James Street, which street are you in?

The physical path of a GPON install is a fibre pair blown through a re-usable "microduct" conduit.  That bit of pipe shown outside the house is connected to another bit of pipe going across the property.  Fibre is then blown from the cabinet to the home and spliced at an external box on to the internal fibre going to the ONT.  The passive splitters will typically be at the cabinet, but could be at the Exchange for homes very close to an Exchange.  The cabinet runs back to a ISAM port which can serve 32 homes (based on the splitter--there are also 2, 4, 8, and 16 way splitters).  Each PON card in the ISAM has 8 ports.  Each ISAM can house 16 PON cards.  ISAM will be fed via fibre transport back to a Ethernet switch where a service provider has the option to accept the traffic there or pay for backhaul to their handover point(s).

Thanks for that very interesting post.  So a quick calculation gives the result that one ISAM can serve 4096 different premises.  Any idea what an ISAM costs when equipped with 16 PON cards?

Thanks for answering my question about where the splitters are located.

Maverick's description of his install says/shows that the cable from the house is spliced to a multicore cable at the roadside pit. It isn't blown all the way from the cabinet to the home is it?

(Goes back to look more closely at the pictures)

Yes, Mav's install shows a pit with ribbon pulls and not microducting. Chorus is installing microducting now. I can't explain why this install does not. I would guess these access conduits were installed before the microducting method was used or perhaps it was physically built by some other LFC. The blown fibre will be faster to install/replace. But it is is probably going to be more cost effective to use existing facilities where possible.

What do you mean exactly by "ribbon pulls"?

When you say "microducting" I guess that you are referring to the green plastic pipes that I've seen being installed alongside roads, and in the very narrow trenches that are cut into footpaths and streets?

From what I've read, orange pipes always signify buried power cables, whereas green signify telecommunications.  Is that correct?

Microducting is the name of the conduit system being used by Chorus currently. It is functionally just a plastic pipe like other conduit, but it is designed to seal tightly so you can actually use air pressure to blow fiber through. Without blown fibre you need some other way to thread the cable through a pipe. This install shows a number of blue ribbons which run through the conduit so the installer can literally pull through the fibre with the ribbons.

I don't know what colour these microducts will always be, just that their utility is different from ordinary piping. Properly installed a microduct could allow fibre to be blown in for a couple of kilometers. The range on a ISAM is between 20-30km. Most of that distance will be on a single fibre pair to the cabinet where the split occurs to reach homes.

Strange that in the modern age of high-tech data networking it all comes down to digging better ditches and finding better ways to pull cable.

Thanks for that Masada.  I can see the ribbons you mentioned now, but hadn't realised what their purpose was.  Cheers.

 fyi all, just upgraded the plan to test the 100 / 50


So my folks live in ChCh, in a new subdivision with fibre.. and been with xnet on fibre for 2 years..
can they upgrade to 100/50?
