Hi,

 

UFB is going into our street at the moment and I'm pretty excited about. I'm trying to get my head around the various components and what goes where. I've read a little about GPON and get the basics.  Today one of these was planted just outside our house.

 

 

I was talking to one of the guys and he said that it was fed from a cabinet and that it then fed 52 houses in the area. Is this where the optical splitter lives? My understanding was that the splinter would only feed 16 houses?

There are multiple splitter boxes in that road side pit. These things have replaced the old school fibre cabinets that were used at the start of the UFB Project.

Inside that pit will be an ABFAT (air blown fibre access terminal). This if where your house will be connected to. In the early days of UFB they had above ground cabinets however these have now been replaced wither either above ground ABFAT, or underground if possible in newer builds.

 

Chorus have some fairly good documentation on their site if you look.

This is a good doc, a couple of years old but still relevent.

My street/area was done at the end of 2012 so has above ground parts like these:

 

 

and:

 

 

If I had a dollar for every one of the green plinths with a missing or damaged cover that I've seen around here, I'd be doing very well.

 

If some drunk idiot took out the type of cabinet in my second pic it'd be a big job to fix it again. These cabinets have up to 300 potential UFB connections.

You know how they're currently replacing Alcatel 7300 rural copper fed cabinets and Conklins? It is part of their evil plan to move them to metro "ufb available" areas.

 

But here is what I am connected to:

I've got one of those pit things on my verge too.

 

The guy working in it said the fibre would be blown down the tubes, but the tubes were currently empty.

 

There could have been 50 odd tubes, didnt really take time to count them.

 

He also mentioned something about green above-ground covers, but ours is still a grey tubey thing.

 

I do notice some in our street have had their grey tubey ones replaced by the light-green boxy one.

 

Why just some and not all I do not know.

@TimA was likely on dialup up until he got VDSL and saw the light. He'll be on it for the next 20 years.

The VDSL2 withdrawal proposal never happened - but IMHO should unless an RSP has a very good reason for needing VDSL2 at a site (and there are plenty).

Are they still extending VDSL? Or is it all fibre build now?

I agree, there are legimeant situations where VDSL is still reasonable to have.

 

 

 

but people with the @TimA approach, Certainly it should happen.

 

TimA: Here i still am not getting fibre even tho i have an ONT in my house.

Rather my VDSL get 998 and i can have bragging rights. But my 65/10 is still cheaper than 100/20 or what ever it is now.

That Tub or Manhole will house ether an ABFAT (Air Blown Fibre Access Terminal)-  Which will handle up to 48 Air Blown fibre connections (3 x 16 leg Spliters) or a similar device for feeding 48 connections on to a or multiple FATs that will feed Fixed Fibre Connections from either off poles, below ground terminals or even terminals housed in buildings.

 

 

 

If they have also been installing the large multi-way ducting around it then it will be the former.

 

 

 

As has been mentioned by others older architecture had cabinets and other network devices above ground but these are no longer used on newer builds

On the original builds all the microduct laterals (the single ends) were installed up into the rectangular Green Boxes (known as Pedestals or PEDs).

 

On later builds only those that would end up in hard surfaces (footpaths etc) were brought up into PEDs and if they were to end in soft surfaces (grassed areas etc) they are buried (mostly right beside the grey terminals used for the copper connections), these are then dug up, when required, joined on and reburied.

 

Then on even later builds the PEDs have been replaces the Hand Holds (the below ground mini-pit with the round green lid) - those in soft are still buired but are now normal marked with a black Peg plastic peg with the Chorus logo on top to help with locating.
