All Internet traffic is transferred on a chip in 1 second | Digital Trends Spanish


A team of researchers has made a breakthrough in the transmission of data via fiber optics by using a single computer chip to transfer 1.84 petabits of data per second, which is about twice the traffic of the entire Internet (or about 230 million photo downloads per second).

Asbjørn Arvad Jørgensen of the Technical University of Denmark in Copenhagen and colleagues from Denmark, Sweden and Japan used a photonic chip, a technology that allows optical components to be built on computer chipsto split a data stream into thousands of separate channels.

The team divided the transmission into 37 sections for each fiber-optic cable core, then divided those sections into 223 pieces of data in the electromagnetic spectrum, transmitting them all at once over 7.9 kilometers without interfering with each other.

“You could say that the average Internet traffic in the world is about one petabit per second. What we broadcast is twice that,” says Jørgensen in New Scientistst. “It’s an incredibly large amount of data that we’re sending across, essentially, less than a square millimeter. [de cable]. It just shows that we can go much further than we are today with Internet connections.”

While not as fast as the 10.66 petabit-per-second data transfer rates currently possible, the beauty of this record-breaking achievement by Jørgensen and his team is miniaturizing. Compared to the bulkier computers currently used to reach speeds of 10.66 petabits per second, single-chip scaling to match or even exceed that transfer rate will remain extremely compact.

As it is, Jørgensen further believes they can improve on the current setup and create an even smaller matchbox-sized on-chip design. Instead of multiple lasers in parallel, they want to shrink the equipment down to the silicon level.

The team also theorizes that if their system is built to the size of a small server, it could transmit as much data transfer as 8,251 matchbox-sized devices currently do when configured in a single parallel system.
