Ericsson shows off 550 Mbps broadband over copper
BOFFINS WORKING FOR ERICSSON have showed off a broadband line that reaches speeds of 500Mbps using ordinary copper cables.
Based around Vectorized VDSL2 technology, the system is a Nintendo bit faster than the 2Mbps that most British punters have to put up with. To be fair, Ericsson joined six copper lines over 500m to manage this speed, but it still means that each wire was sending around 83 Mbps.
ADSL2+ can just manage 24Mbps and Virgin Media's own cable connection tops out at 50Mbps and both of these need crosstalk software to reduce the noise on the copper cables.
However if BT ever adopted it, it could save a fortune because it would not have to replace existing copper cables with expensive fibre optics. Even with a 83 Mbps speed, HDTV and video on demand is possible.
Ericsson, however, seems to think that VDSL2 will be better for fibre extensions and could be used to combine fibre-optical with last-mile copper depending on the environment. µ

If the telcos had six pair to most dwelling units, this would be exciting. Alas, that's hardly the case. Most dwelling units are served with two pair, rarely three or four.
The operators and/or building owners, e.g., BT, would have to place additional or replacement cables to the units. If they have to place new cable in any case, they would certainly choose to deploy fiber.
I'm far more interested in which speeds are available on two real-world pair with a bit of water and corrosion present.
We'll be watching Ericsson, but I'm not selling my fiber stocks.
Its neat idea for array, yet ericsson isn't any fav.EEE. for example, peoples teeth tell lot about quality of their society. Cann't say swedes have much going for them except extreme dental problems( & lots of Ore). Sure Radio is big facet there & ericsson fills mountains with hope, yet its still Not That great of company & light weight electronics. Both Telco & Cable can offer up to 50 Mb/s for about $50/Mo. So advantage is limited & distance is short. Yet its good imitation of others & just as fast or faster. STeWie drashek
the system is a Nintendo bit faster than the 2Mbps.
whats with the use on Nintendo, is it a new term for the word large or somthing
It's a copper pair bonding technique.
6 copper wires = 3 pairs.
It costs considerably more to rewire an existing premise with fiber. Why not re-utilize the existing copper phone lines. It's still possible to reach near 100mbps with VDSL2 Profile 30a.
If you can get such speeds under distances of 200m, who needs FTTH?
GEPON/GPON works on shared bandwidth anyway. It brings fiber to the basement and the streets.
In the future when isps are ready for faster speeds, they could always provide fiber drops further into customer premises.
VDSL2 deployments makes more sense considering the savings telcos can make.
"Virgin Media's own cable connection tops out at 50Mbps"
Actually it doesn't top out at 50Mbps (docsis 3) however that is the top package at this time. VM are trailing 100Mbps however at this time it's it's said docsis 3 can reach 320Mbps
It goes like this: Little bit faster -
We bit faster - Wii bit faster - Nintendo bit faster
It's simple really
That's right Defiant.
With DSL copper lines we bond lines but with cable we could bond channels on a single line.
Bonding upto 8 channels on DOCSIS 3.0 will give isps the option to offer speeds of over 400mbps based on EuroDOCSIS standard.
