PON is relating to the final splitter and the number will vary based on local geography and topology of ducting/poles.

The TCO is not really changing, some who get lucky with the premises passed on PON will be better off, but many are not going to be, and FoD is not intended to a be a massed market product.

The new setup is more more favourable for things like voucher schemes, which are increasingly common as councils shy away from further large BDUK type deployments.

Alternatives exists but not here.

French multinational company Orange since 2017 offers LiveBox4 with built-in SFP ONT which can be easily moved to the L2 router.

Canada Bell since 2016/2017 offers HomeHub 3000 with SFP's from severals vendors like Huawei or Nokia

Fibre is not something magical. It is based on open ITU standards. Many consumer oriented products can be used without major inconvenience.

With the new XGPON options allowing 1000mbps, how does this work with only 1 gigabit Ethernet port? Gigabit Ethernet is only about 6-700mbps, not 1000, ...

I have no idea what sort of kit you use to get such poor throughput on gig ethernet - but I suggest you get better kit or config.

Gigabit ethernet gives a TCP throughput of 942Mbps(*) once all the various headers have been taken into account.

It's easy to saturate gigabit on pretty low-end hardware, given a decent operating system. I expect you have been running Windows.

(*) That's with IPv4 and MTU 1500. It's about 928Mbps with IPv6, because of the larger headers.

In both cases �

I'm not sure if you're suggesting Windows isn't any good or not, but Windows EASILY handles it - and way beyond on pretty basic hardware. Has done for a long time.

I'm saying that I've seen many Windows boxes (particularly laptops) which only achieve 150-300Mbps, but if you reboot them into Linux, you get the full 940Mbps.

I presume that many of the Windows drivers for cheaper NICs are pants.

Cheap laptops can be awful in Linux too for various reasons.

The laptop might of had loads of stuff running in the background (i.e. bloatware).

I know when we are sending loads of data, media content (from a Windows 10 PC) over our LAN to one of our internal servers running Linux we get about 880Mbps to 910Mbps, so its not a Windows issue.

But you will never get the full 1Gbps over a Gigabit LAN due to all the overheads / headers in the packets.

Like most TCP headers will take up 54 bytes so with a TCP packet over TLS it will send a packet of size 1,494 bytes, now 54 bytes of that will be the TCP Header leaving 1,440 bytes that means that 96.38% of a 1Gigabit Lan will be data, so about 960Mbps, sure we could use Jumbo Packets, but not everything likes those.

But you also need to think about is not all packets are 1,494 bytes in size, they could be a lot smaller, but the TCP header will still be 54 bytes in size, so that would also reduce your data transfer over the Lan.

Agreed,
I have a (temporary) Mini-ITX Server here running Linux which we are using for our DHCP, DNS Services plus other internal stuff, now everything works apart from the LAN just dies on it for some reason, nothing in the logs nothing, only fix is to re-install the drivers and or re-connect the LAN cable, seems loads are having this same issue, and this was down to the Realtek 1Gbit Controllers it uses being a pile of poop, yet it works great on Windows.

Yet I can buy a very cheap PCIe Gbit Lan card and it will be fine.

What I am trying to say is, its all down to the quality of the drivers, you could have hardware costing thousands and it will be useless if it had rubbish driver support for it, at the same time you could have some cheap Chinese knockoff device that cost a couple of quid (if that) but have very good driver support and it would work great.
