Вчені побили рекорд швидкості передачі даних через оптичний чіп

Scientists continue to blow through data transmission records, with the fastest transmission of information between a laser and a single optical chip system now set at 1.8 petabits per second. That's well in excess of the amount of traffic passing across the entire internet each second.
Here's another comparison: the average broadband download speed in the US is 167 megabits per second. You need 1,000 megabits to get to a gigabit, and then 1 million gigabits to get up to 1 petabit.

No matter how you present it, 1.8 petabits is a serious amount of data to transmit in a second.

The supercharged data transfer system is built around a custom-design optical chip, which uses the light from a single infrared laser and splits it into hundreds of frequencies. The frequencies are isolated at fixed distances from each other, like teeth in a comb – hence the name for this setup, which is a frequency comb.

Each 'tooth' on a frequency comb can send its own burst of data, which is how the huge transmission rates are achieved. Using more conventional means, around a thousand lasers would be needed to carry the same number of 1s and 0s.
