FTTP for a minority off a cabinet

I have found that OR have installed 'overhead' fibre to about 30 premises from my cab (6 port distribution points have appeared on the relevant DP's and the Broadband Availability Checker confirms FTTP available).

My question is why just a 'random' choice of a small number of premises and is it a precursor to the whole cabinet going FTTP ?.

Also intrigued as to why overhead fibre (there are yellow markers on the relevant DP's saying 'Warning Overhead Fibre')

Warning to make sure that people don't do things that break it

Some areas start out as a small bit done and then expand, others are because of a small community project, other are funded to get people from below 30 Mbps to above it. So which it is will depend on the location.

Overhead, because it’s cheaper to deploy.

Unless things have changed dramatically recently, no FTTP is supplied from cabinets.

I didn't realise that (on the checker for a property that I know has FTTP it still states the Cab number). If they are not fed from the cabinet, how are they fed ?

The copper line remains in place for most people and thus the cabinet number remains, in the same was ADSL2+/VDSL2 estimates remain.

If they have none of those estimates exist then suggests it is a fibre only supply which is usually for new build properties (some very long line ADSL2+ where FTTP gets rolled out see the ADSL/ADSL2+ figure vanish since no connection was possible too)

There may be a few cabinets in villages where a spare fibre gets reused to suppy the GPON FTTP for that area, but this will be fairly small cabinets. The 99.9% rule is the fibre comes from an aggregation node, this may be next to a cabinet in the ground or it might be some distance away depending on network topology in the area.

Only from X2 subtended headends being installed in many cabinets, but that probably wasn't what the OP meant anyway.

Now there is something that will have a fair few readers (including myself) googling .

Thanks for that info though. I don't like posting incorrect info.

Is this something relatively new please? Or was it always the case?

Thanks Carl .

Mark Jackson's article is fairly easy. The Huawei one requires knowledge I don't have, but I can get the gist of it.

What your and witchunt's posts amount to is, in short, that things have indeed moved on since FTTP was first introduced by Openreach.

So it is possible the OP's FTTC cabinet is providing the FTTP service to the village, if it already has FTTC?

Our cabinet was BDUK funded to get FTTC, but only the closest houses got 'superfast' and at my end of village we where around 5MB, further BDUK funds where found to extend FTTP to our end of village, this fibre came past the houses with 'superfast' but checking Openreach website it seems it wasn't put up their poles as they show only FTTC as being available. So it might be a similar reason.

Perfectly normal and business as usual for what you describe.

interesting comment but FTTP Still has to find a path back to the exchange and primarily will not be using the FTTC Blown Fibre path - or the cabinet as it has to get the to an aggregation node (normally deeper in the network) to enable it to get back the main headend (this could be a number of kilometres in smaller exchanges

hav had to reregister as former email account defunct (I am former Fastman)

Rather annoyingly I've just cycled down the road to cabinet and forgot to look at poles.
What I can tell you is that the fibre in our road was laid from the area of cabinet, but if it was taken beyond that I don't know, I suspect it is as t'other week all the FTTP went down and the engineers where working in chamber near cabinet when I cycled past them, a while later on my way back they had moved further down road towards the exchange.

Given fibre will be using existing ducting or poles where possible going close to a cabinet is the norm

I'd say it's the opposite of that. FTTP will primarily be using the same path as the FTTC fibre path.

There is already ducting in place between the cabinet and the home.
There is already ducting in place between the cabinet and the Aggregation Node. That's where the fibre feed for the FTTC cabinet comes from.

It's very common for FTTP rollouts to follow this route. They avoid installing new deducting where possible.

My own line is about 1km in length to the cabinet.
I just had FTTP installed.
The new fibre travels around 900m down the exact same ducting.
Around 100m before my cabinet the fibre branches off left towards the Aggregation Node, down the exact same route my FTTC cabinets fibre comes from.
So my FTTP cuts out the last 100m to my cabinet as it cuts across to the fibre spine.

Edit: obviously this isn't the case for every area.
Just more often than not the fibre will use all or most of the route the copper currently takes.

Rural areas can be an exception to this.
As can areas where the copper goes to a different exchange to the 1 the fibre goes to.

I can tell you that's not the case for my FTTP(oD) installation. It *does* use existing ducting, but does *not* follow the path of the copper.

Speaking roughly: the exchange is due South from where I live (and my FTTC cabinet is right outside the exchange); the fibre aggregation node is due South West.

I've seen the engineers drawings, and my FTTP path follows ducts which make sense to head towards the fibre aggregation node, rather than first heading to the exchange and then across to the aggregation node. It even goes past a different FTTC cabinet en route.

It makes sense when you think about it: FTTP forms a tree out from the aggregation node, while the copper is a tree out from the exchange. The two aren't necessarily co-located.

Agreed, I know our fibre cable goes the same route as our copper at least to the main road where our cabinets are located, where it goes from there I wouldn't know.

Yesterday I was out on my bike again and took more note of the properties supplied from our cabinet, this is probably only of interest to myself, but the OP might like to know he's not in the minority.
Our BDUK funded FTTC cabinet was installed between two small villages, it is close to the edge of one 'compact' village and I believe all (or most) of the properties there are 'suprfast', there is no sign of FTTP.
The first pole for my village is around 400m from the cabinet, and the village is linear(?) stretching away from the cabinet along a zigzag of roads for 1.4km, so a total of 1.8km from cabinet to last property as the lines run, understanderbly only around half these get 'superfast' FTTC. Last year BDUK funded FTTP was installed for the last half of my village to enable 'superfast' for all. As I cycled along I noticed that the first 6 poles had no fibre, then one had fibre, then two more with no fibre, then the remaining poles to, and beyond my house had fibre.
