The result, achieved by scientists at University College London, uses a series of signal processing techniques to achieve the speed.
The fastest data transmission rate ever for digital information between a single transmitter and receiver has been achieved by a team of researchers. The data rate is the speed at which data is transferred within a computer or between another device and the computer. Researchers will now analyse achievable data rates in long fibres - up to transcontinental length. "To give an example, the data rate we have achieved would allow the entire HD Games of Thrones series to be downloaded within one second", he added.
"For comparison this is nearly 50,000 times greater than the average speed of a United Kingdom broadband connection of 24 megabits per second (Mb/s), which is the current speed defining "superfast" broadband".
The 1.125 terabits per second speed, achieved in lab conditions, is almost 90,000 times faster than internet speeds typically found in USA homes.
There's a small but, though: In these experiments, the team directly connected the transmitter to the receiver. "A high-capacity digital communications infrastructure underpins the internet and is essential to all aspects of the digital economy and everyday lives".
"The focus of our work is to develop new techniques and subsystems that will push the limits of ouroptical communications systems", said Robert Maher, study lead author and a senior research associate at UCL's Electronic & Electrical Engineering department, over the phone.
"This result is a milestone as it shows that terabit per second optical communications systems are possible in the quest to reach ever higher transmission capacities in optical fibers", said professor Polina Bayvel, principal investigator of the Unloc program at UCL, in a statement Thursday.
The way Maher and his colleagues set up their new system was to combine 15 different channels through which to send the data, and each one carries an optical signal of a different wavelength.
Grouping channels together in this way created what the team refer to as a "super-channel", generally believed to be the future in next-gen communication systems. All channels are separately modulated and then combined into a single signal and that's what the researchers call the "super channel".
Researchers f have broken the world speed record for transmitting information digitally. And that's not going to be easy, because optical signals are at risk of becoming distorted as they journey through thousands of kilometres of optical fibres, and that's no good for anyone.
