its GPON with 2.4Gbps shared via 32 way splits
So is that contended locally? Theoretically if all 32 splits download at once, the bandwidth could be as low as 75mbps per user?
Not too sure, I know we have 4 fibres going into our Splitter Node and each of those 4 fibres have a downstream speed of 2.5Gbps and an upstream of 1.2Gbps and each of those 4 fibres are split 32 times.
So 2.5Gbps (2,500,000,000) / 32 = 78.125Mbps downstream and 1.2Gbps (1,200,000,000) / 32 = 37.5Mbps upstream and that's the speeds everyone would get if everyone with 300 / 20 hammered their connection.

If I recall correctly, the minimum download speed for 330 is 80Mb, for 220 & 80 it is 40Mb. (The minimum speed is that which below you can log a line speed fault)
Even FTTP is sold as "UP TO" a speed.

That fits my recall (without finding source docs).
But yes FTTH/FTTP is up to still, unless it is sold and provisioned with 1:1 contention i.e. a leased line.
All FTTH does is remove the uncertainty over connection speeds, it does remove the reality that providers never have enough capacity for all users to use full capacity at the same time (maybe the odd exception with new start-ups when the first 2,000 are connected out of 100,000 they hope to reach).
In many of the FTTB deployments across the globe, lots are such that people have 1 Gbps to their apartment, but the fibre leaving the building is still just a 1 Gbps link or maybe 2 x 1 Gbps. Hence why average speeds in countries with lots of gigabit connectivity are not in the 500 to 600 Mbps region.

That's very interesting, I never thought about that.
On our development there will eventually be 199 homes but I don't know the amount of cable coming into the node. Is there anyway to find this out?

Which provider/technology are you talking about?

FTTP.

More than enough to provide the capacity for Openreach FTTP (assuming its Openreach involved) GPON on current standards, and ready for hardware swaps to support faster 10 Gbps PON standards in the future.
The capacity in the local access segment is likely to be a LOT better than what individual providers budget for.

Yes it is Openreach, I had a brief chat with one of the engineers yesterday as they were installing ONTs into the first few houses.
Good to know though. Thanks.

I think the 10 Gbps PON will be when they increase the overall speeds of FTTP, this will probably happen when G.FAST goes live for the FTTC people.
Well I am assuming here.
That "would" give FTTP a minimal speed of 312.5Mbps if everyone hammered their connection, this is also assuming that a single fibre stand going into the splitter node is still split into 32 strands.

I'm happy enough with my 75Mbps average download speed on FTTP, and it is sufficient for my household currently. Though if I did move provider I would go for the 330/30 option for future proofing.
Issues with congestion at the exchange/provider gateways are more pressing to me, tonight TBB speed test is like a picture of the Alps and the average has dropped to 55Mbps. Start of the long nights and football on IPTV saturating the providers bandwidth.
