In October last year a team at the Photonics Engineering Department of the Technical University of Denmark (DTU), succeeded in breaking the so-called 'terabit barrier' in data transmission, by using laser pulses to send data down a fiber optic cable at a breathtaking 5.1 terabits per second. News of that success has travelled around the world at a commensurately high velocity, with the US in particular taking a great deal of interest, states a press release from the Danish Ministry of Science, Technology and Innovation.
Now a collaboration has been announced between DTU and Stanford University following a workshop held at Stanford by the two institutions, which will now join forces on researching into the ultra high speed internet of the future. Commenting on the separate competences of the two teams, Professor Leonid Kazovsky of Stanford University's Photonics and Networking Research Laboratory says in the press release:
"At Stanford we are working on optimising the data network, while our Danish colleagues can give us the high speed and specialist knowledge on how we accomplish data transmission between for example fiber and wireless technologies."
Meanwhile the IT industry in the US has also picked up on DTU's terabit-breaking achievement. Ashok Krishnamoorthy, an engineer at Sun Microsystems who tracks new technologies, comments in the press release: "The world record is an important milestone, and the surprising thing is that it was set by a university and not by a major IT company."
Professor Shawn Searles at microchip producer AMD is similarly impressed with DTU's high speed breakthrough. "It is the first time I have seen such a method demonstrated successfully. The technology will be able to solve the asymmetrical problems in data transmission, where today we have a big difference between download and upload times," says Searles.
And the USA's largest provider of internet and telephony services, AT&T, has noted the energy-saving aspect of DTU's technology which high speed communication in fiber optic cables promises.
