Adtran and Nokia have 2.5g port units available to OR (Nokia G-010G-T and ADTRAN SDX 611Q)

how common are aggregation nodes or is that the secret how long is a piece of string

That's a rather strange question, I would say they are extremely common wherever FTTC cabinets and FTTP PONs are deployed. They are just collection points where fibres from FTTC cabinets and FTTP Splitters come together from a geographical area before heading back to the head end exchange. What are you actually trying to find out?

I think I read there's typically one between every 4-5 FTTC cabinets.

Note that since the copper networks and fibre networks are independent, it's quite possible that your copper cable heads in one direction (towards the local exchange) whilst the fibre heads in another direction (towards a larger head-end exchange that drives FTTP). The FTTC cabinets will also have fibre connections back to the head-end exchange, and that is likely to be the same one.

Almost certainly the same headend and if you're very early FTTP build potentially the same OLT. We were a new build in an FTTC area so among the first to go onto FTTP. We're on a Huawei OLT that was originally installed to backhaul BDUK-funded Huawei cabinets.

Thank you candlerb, that was the answer i was looking for. The reason i as was two fold, one in general, because its never really discussed partly because of security. The other was selfish and trying to work out how many our village had, 13 fttc units over a larger area and I was wondering if some where going one way and others another. They are also finishing off fttp rollout cab by cab which is interesting.

Our exchange got moved from a shed sized thing to a double portacabin sized thing. I'm expecting the head end exchange is christchurch

will they for a village use existing fibre connections (since theres usually quite a few spare) to back to the olt. Just wondering how much is re-used.

Quick update.

I have come to the conclusion BT are utterly hopeless and have already given up on serving customers.

Short story is, I logged into our account a few days after the order, they had cancelled it. No warning, no heads up, anything.

According to them, Full Fibre isn't available and they blamed Openreach.

Openreach was contacted, and they repeated their earlier info that it 100% was/is available.

We told BT to sort their [censored] out and to get it sorted out. 10 days or so later, BT are still saying "No" after re-ordering the cable link and now saying only "300" service is available.

Speaking directly to Zen, Vodafone and others, they all say 900+ is 100% available and just an order away.

I am 3-4 hours of communications in with BT and ready to throw in the towel and bin them off. It's utterly pathetic how they have handled it and and apparently re-looking into if they have the wrong info - or if indeed Openreach are lying to us.

I have no idea now what to do? 35Mbps for now though I guess.

So there is your answer. Get FTTP from a different isp.

100% this. And if for some bizarre reason, even after this experience you *still* want to order FTTP from BT (why?!), then take the 300M service they have offered.

I have FTTP 300/50, although not from BT, and it's plenty. You almost certainly wouldn't notice the difference with 500M or 900M, especially over wireless.

Sounds to me like BT have insufficient cablelink capacity at your exchange.
