Laser puts record data rate through fibre

Post by Loner » Mon May 23, 2011 12:52 pm

Researchers have set a new record for the rate of data transfer using a single laser: 26 terabits per second.

At those speeds, the entire Library of Congress collections could be sent down an optical fibre in 10 seconds.

The trick is to use what is known as a "fast Fourier transform" to unpick more than 300 separate colours of light in a laser beam, each encoded with its own string of information.
