Beyond the pilot, BT needs a vendor that can give them 48-port and 96-port nodes, which don't exist yet. I'm surprised they'd want to lock down on vendor choice just yet.

BT had a 'Investor Day' (webcast on their site) recently where they briefly mentioned they had chosen a chipset for their 25,000 pilot but as you say they will want to keep their options open.

I believe 96 port nodes should be available by the end of the year.

As I posted above, I understand that Alcatel and Huawei units are using Broadcom chips and Adtran Sckipio chips. Broadcom's chip supports VDSL as well as G.fast.  Sckipio's chip seem to perform better better but some telco's may want the flexibility of continuing to support VDSL.

Why are you looking into G.fast chipsets when G.fast may never arrive at are doorstep it's a 10 year project and anything can happen from now to 2027

Well as I'm closing to the Cab I'm expecting it by 2020 rollout should start summer 2017, but I'm waiting on what the revision to the spec brings Hopefully it
ups the range to 400m.

It just seems to early to predict or theorize on the hardware they will use but that's 3 years away for you and 5 - 10 years for me.

I just find it weird/strange to speculate on something that is in the future not just a year from now but 10 years into the future, me I would just stick to the current OR technology gezz we are still trying to work out how the DLM works  ;)

Well looks like neither BT or anyone else will be using Ikanos chipsets...!

BT should be thankful for vectoring eh?

Quote
Tests on the older, unshielded cables found in many buildings in Austria achieved speeds of 500 Mb/s over 100 m when a single line was active. However, when a second G.fast line was added, crosstalk dropped G.fast speeds from 500 Mb/s to just 60 Mb/s. G.fast with prototype Vectoring 2.0 technology removed the crosstalk and brought the speed back up to 500 Mb/s over 100 m.

Both G.Inp (G.998.4) and G.Vector (G.993.5) are integral components required for a successful G.Fast (G.9700/G.9701) implementation.  :)
