"The only power requirement at the customer end will be for the router, not to convert a Fibre path to a coax path then a router.
Now honestly, which will end up being the more reliable, greener, and end user friendly"
I agree NDNIC, VM's network does appear to be a complicated mix of Equipment's, highlighting a evolutionary process rather than a complete redesign. From what I've read BT are going for a completely new network, with the legacy network scrapped. BT's local access network will mainly consist of three elements, the OLT at the Head End, Fibre and splitters, and the ONT's at the customer premises. Once the customer data arrives at the OLT, it will be aggregated with data from other OLT's and then carried to the cloud routers, via DWDM, using equipment like the Ciena 6500 featured in the VM Head End video. The Backbone Switch/Routers might be Juniper, like the one in the VM video, or big Cisco Network Switch/Routers. BT will likely have specialist servers and routers dealing with some of the more complex specialised functions, but it'll all be embedded in the cloud. From an Engineering and maintenance perspective, BT's network should be easy to maintain at the local level, with all the complex functions built into the cloud. Maybe VM intend to use the £10 Billion, they are looking to borrow, to replace their current legacy network, but I haven't read anything to suggest that.
All the DDF's will go, and all the connectivity will be over Fibre's feeding into High Density ODF's.
Big business customers requiring much higher levels of secure access, like banks, have dedicated Fibre connections, with secure VPN pipes across the cloud, which aren't cheap. Big business customers will always require more specialised managed services, so things wont change much there.
