BT rival Virgin Media has trialled a 40Gbit/s live network connection over a 217 mile span of its existing 10Gbit/s backbone from Manchester to London.

Virgin Media said that the trial would be used to demonstrate whether it would be economically viable to both optimise existing optical network assets and scale the network upwards so that it offers high data transmission rates.

The firm's technical architecture director Daniel Hennessy said that the aim of the trial was to continue to meet the growing capacity needs of the high-speed services needed to service Virgin Media customers, "Our strategic suppliers have demonstrated very clearly how existing network assets can be scaled to meet the growth in demand associated with evolving customer behaviour.”

The trial used Nortel Networks’ 40G Adaptive Optical Engine dense wavelength division multiplex (DWDM) transponder cards, terminating on Juniper Networks T-series routers which had 40Gbit/s interfaces.

Nice :cool:

er yeh if its anything like virgin its 8 meg realworld = 3.6, 20 meg realworld = 7.6. 40 realworld = 9.6

Thier full of stat and no action, branson needs to sell his hot air balloons and deliver on some promises! The Jerkoff!
 
My 20Mb connection is always maxed out, well unless I've gone over the limit between 4pm and 12am, otherwise it's always at around 2000kb/s.

Fantastic service.
 
Branson has little decision making power in virgin media. When ntl:telewest bought virgin mobile, part of the agreement was to change the name to virgin media. Its not owned by branson, he is not chairman, he is not CEO or anything like that. Not that what you said was entirely true anyway as i always get the speed i pay for with VM, its only the over subscribed areas that dont.

As for the upgrades to the cable network itself, its good that virgin media are preparing for the future and testing out upgrades that will improve the network.

You mean Virgin ADSL?

/pft
 
40Gbits over 10Gbits. Smart.

And anyway no home user would ever need this speed. Just sounds like Virgin generating free PR for themselves.
 
The point is that it would be an upgrade to their core, so that they could support large numbers of high bandwidth users. It isnt for end users directly. Take a look at the cost of a Juniper T series with a 40g interface ;)
 
urm think you all missed the point, this isnt a speed for end users, this is an upgrade for their backbone networks. basically upping the capacity that they have for internets

You should be getting more than that on 20MB, I've got just over 22mb, and I regularly get around 2.5MB-2.7MB/s :)

How can you get 22mb? Highest I’ve seen on the VM forum and speed test is just below 20mb, Highest I’ve had is 2.45MB/s
 
I'm guessing this increase results from shoving even more frequencies of laser light down the bit of glass and then being able to reliably seperate them all at the other end. It's a nice boost to existing fiber runs :)
 
I'd get their soon-to-be-10Mb 4Mb service if I could, they're meant to be very good in this area. I'm happy with O2 for now though, I just have to accept that it won't be going much quicker than 6.5Mb anytime soon.

Don't know what they're using, 40Gbit is a ethernet standard in the making (though I think it'll be skipped by most in favour of 100Gbit which is only slightly behind). Could be CWDM or DWDM of course but I'd be slightly surprised.

Hey, sorry about that, I'm on ADSL, and I live on-top of the exchange... well almost :D about 40m or so away. :)
 
You know this is only a backbone speed?

This isn't to homes...

With this new back bone they can think about pushing 150mb to home pcs.

And 20mb is 20mb with VM mines been awsome :)

And i'm really really looking forward to 50mb :D
