Well it's certainly a boost but while my net is 1gb speed I know from the engineer fitting it stated it can send 10tbs if allowed but its still a huge increase so we'll see this speed never lol.
Yep in the UK if you are on Fibre and I mean actual Fibre the glass cable, then you can basically get whatever speed the ISP is able to provide via the NTE they install and what you device can handle.
If you are on ADSL then it's about 100Mb max if you are really lucky and right next to the exchange.
If you are on Virgin then realistically that can go to 2.5Gb synchronous (if they ever bother to allow it) over the "Co-Ax" cable but anything above that then it's recommended to go Fibre. Virgin though now are moving to full fibre including eventually swapping out the Co-Ax for fibre.
The issue then is the PC's because the "Normie PC" is barely able to cope with 1G down, never mind 10G or even 100G, then there is the drives, Sata and SAS are not going to cope with 10G or more really, without some fancy caching drives but then they will eventually fill and you are dropping speed because the drives cannot keep up.
My server with 2x Xeon 10 Core 20 Thread CPU's and a SAS-3 HBA with 24 SAS-3 HDD's connected maxes out at about 180Mbp/s read speed from the drives currently, I suspect they would go to maybe 250Mbp/s if I was on a 10G network, but that is still only 2.5G.
The technology this article is based on, will mainly be used for peering links from the UK to France etc as it will allow those existing cables to have a new life, and will increase revenue for the peering companies, it won't really affect us "Normies" because we will still be getting the same speeds we are now, at around the same prices but the likes of Virgin, BT and Vodafone will all benefit as they can also use it on their backhaul cables, to dramatically increase bandwidth.
