For many homes and businesses in the UK an internet speed of 10 Mbps would be heaven, sure there are services offering superfast broadband in the main cities and towns of the UK, but this does not cover the rural and some coastal areas of the country.
So you can imagine our surprise to see that some researchers are talking of a broadband service of around 26 Tbps, just to put this speed into perspective, you would be able to send down a thousand high definition DVD’s every second, now that is fast!
It is all down to laser technology, this is literally broadband at the speed of light and surprisingly speeds of around 100 Tbps has already been demonstrated in test situations using 370 lasers! However, this set up at the Karlsruhe Institute of Technology in Germany is using one laser, which is more practical.
According to Prof Wolfgang Freude, from the Karlsruhe Institute of Technology in Germany and who is a co author of the paper on this technology;
“Already a 100 terabits per second experiment has been demonstrated,”
He said when speaking to BBC News.
“The problem was they didn’t have just one laser, they had something like 370 lasers, which is an incredibly expensive thing. If you can imagine 370 lasers, they fill racks and consume several kilowatts of power.”
So clearly this is at the experimental and development stages, but if we think back ten years to what the average internet speed was, then ten years into the future, this could be a real possibility.
