“A team of U.S. researchers say they have discovered a process by which to transmit upwards of 2.56 terabits of data per second using twisted beams of light.
Twisting light to send data at dramatically increased speeds may be used to build high-speed satellite communication links or be adapted for use in the fiber optic cables that are used by some Internet service providers. It may one day be commonplace to download data packages the equivalent of 70 DVDs in one second, say scientists, citing research that shows a new high-speed data transfer breaking records.
The technology has potential applications for high-speed satellite communication links, short free-space terrestrial links or could be adapted for use in the fiber optic cables used by some Internet service providers. Researchers noted that the test conducted resulted in data transfer speeds 85,000 times faster than broadband internet speeds, some of the fastest ever recorded.
The test was conducted by harnessing the power of light, which scientists manipulated in order to better facilitate the transfer of data. The present study saw a single beam of light carry 2.5 terabits per second carried over a distance of 1 meter, but the method could be adapted for long distance, say scientists.”
