Danish research lab at DTU is first to break the "terabit barrier"  

2009.03.06
A team at the Technical University of Denmark has become the first to achieve a data transfer speed of 1 terabit per second
Imagine being able to download 80 full-length feature films, or all the text in a 4½ kilometre high stack of library books, in just one second. To transfer data at this speed would necessitate breaking through the "terabit barrier", and that is exactly what a research team at the Technical University of Denmark (DTU) has achieved, reports DR Business.
 
One terabit per second – or 1 million million bits per second – is an awesome rate of data transfer. Previous attempts have been made by research labs around the world to break the terabit barrier, but none have succeeded. The best attempt hitherto was 640 gigabits per second, which only five laboratories on the planet were capable of reaching.
 
Against this background, the official breaking of the terabit barrier can be seen as quite a feather in DTU's cap. It can also be expected that DTU's breakthrough, achieved using fibre optics and photon pulses, will have no small implications for the future development of data transfer on the internet, where data volumes are increasing at the rate of 60% annually.
 
Faster data transmission speeds also have environmental benefits, since less electricity consumption equates to less production of CO2. At present, the internet is responsible for 1% of the world's entire CO2 emissions.
