UK scientists turn existing fibre up to 20Gbits/sec

Researchers at Bangor University have developed a way to super-charge fibre in a move that could boost broadband speeds on the UK's networks within years.
Using a technique called Optical Orthogonal Frequency Division Multiplexing (OOFDM), the scientists say they can push far more data down existing fibre without dramatically inflating costs, making it ideal for ramping up end-user access networks that deliver home broadband.
The technique effectively enables carriers to push more data down the same pipe, with the researchers claiming the technique has “the fastest transmission speed and highest cost-effectiveness compared to all existing technologies”.
“You could use this to increase the capacity on fibre to the home broadband networks – the access networks - that are already connecting homes and businesses to the network and it's basically using fibre optic technology,” said Roger Giddings, lead researcher on the project.
In our latest demonstration we've demonstrated 20Gbits/sec, which is well ahead of current capabilities
The system would require new transceivers at each end of a fibre line which would then be able to speed data into homes.
“We're working on a small module that would sit with the operator in the exchange and they could swap the module in. Then in the home you'd have another transceiver there,” said Giddings.
“In our latest demonstration we've demonstrated 20Gbits/sec, which is well ahead of current capabilities and we think if we use slightly different components we can push that to 40Gbits/sec.”
One year into a three-year project, the concept is still in search of a technical standard before it could be offered to commercial partners, although the scientists are already working with industry to see how the developments could be incorporated into hardware, and within budgets and power-consumption constraints.
“We're building the transceiver and then system builders would build that into their systems, and people are looking at how we can do that," Giddings said.
Now we can get through a 500MB data cap in less than half a second!

Well done Bangor!
Now can we please find a way to make this discovery benefit the UK and not just get sold off for a pittance for some Korean company to manufacture the parts?!

Is and might be
1year into a 3year research project.
Well ahead of current capabilities.
If it takes 2 or 3 years to complete the research, settle on a standard, patent it, for ISP's to bespoke it and manufacturers to tweak it, will it still be so far ahead? By the time it's actually rolled out it could be 2018. So ASAP if you want it to be a success. Tick-tock, there is other research going on (most of it private).
Where is your market? Where could the backbone cope and where would the ISP's be interested; the UK, Europe or Asia?
