Yup. I’m not sure whether this called is increasing the ratio or decreasing it. But yes, I take this to mean they’ll be experimenting with say 1:64.

That’s an increased ratio (N:1 when N gets larger)

What I’m curious about is how easily they can reassign users in case of oversubscription. If they built to 1:32, are those 32 customers always going to be on the same OLT?

They will avoid trying to move customers between PONs wherever possible.

I believe they can do it, because unlike Openreach’s network which is spliced, they have passive cabinets with splitters and patch panels.

However, every time they decided to re-patch a customer from one PON to another (a) costs to send an engineer out to the cabinet, and (b) risks that engineer unplugs the wrong fibre and breaks service for some other customer.

True, they say that, but see my other post. They won’t be able to advertise a service as 10Gbps, if it’s over XGS-PON.

Cityfibre don’t advertise or sell services to end-users, so they are not bound by any Ofcom advertising codes.

Their resellers, of course, would be. I think they could advertise the service as « 9Gbps » if 50% of customers who bought that service were able to get that speed at peak times.

But TBH I don’t think either Cityfibre or the resellers *want* such customers. The sort of person who is able to build a network capable of pushing 10Gbps *and* who wants such a connection will probably fill it with hourly full backups of their entire pr0n and warez collection, and then will complain loudly on forums if they only get 7Gbps and not 9Gbps.

The point of high-speed connections, beyond a certain point, is not to consume more data: it’s to get the job done more quickly. There are only so many 4K videos you can watch in a day, or games you can download. This is why the extra you pay for high download speeds is pretty low.

But uploading is a different matter.
