Scientists Managed to Transmit as Much Data as the Entire Internet’s Bandwidth

Posted by in categories: computing, internet

The world wide web is not enough, because scientists have managed to transmit data at a staggering 1.84 petabits per second — nearly twice the amount of global internet traffic in the same interval.

That blows the previous record for data transmission using a single light source and optical chip of one petabit per second out the water. And to put that ridiculous amount into perspective, a petabit is equal to one million gigabits. A single gigabit, or 1,000 megabits, is about the fastest download speed money can buy for most households.

To achieve the astonishing feat, researchers from the Technical University of Denmark (DTU) and Chalmers University of Technology used a custom optical chip that can make use of a single infrared light by splitting it into hundreds of different frequencies that are evenly spaced apart. Collectively, they’re known as a frequency comb. Each frequency on the comb can discretely hold data by modulating the wave properties of light, allowing scientists to transmit far more bits than conventional methods.
