Need for Speed: Internet speed is typically measured by how much data can be transmitted between two devices in one second.
The new record is 319 terabits per second (Tb/s). That’s double the previous world record for fastest internet speed and about 7.6 million times faster than the average home internet speed in the U.S. (42 megabits per second).
Fibre-Optic Cables: Different types of internet connections transmit data over different types of hardware. The old dial-up connections, for example, relied on telephone wires, while the fastest kind of internet available today — fibre — uses fibre-optic cables.
These cables transmit data using pulses of light, which travel along thin optical fibres with glass or plastic cores.
It might not be too difficult to integrate the tech into existing infrastructure.
To break the record for fastest internet speed, researchers at Japan’s National Institute of Information and Communications Technology developed an experimental optical fibre with four cores, instead of just one.
They then combined their fibre with a laser that fired pulses at different wavelengths and multiple signal amplification techniques. This enabled them to transmit data over a distance of more than 1,800 miles at 319 Tb/s.
However, there is one part of the experiment that could have an impact on your life in the not-so-distant future: the optical fibre.
The researchers managed to pack all four cores into a fibre the same diameter as the single-core fibres used to deliver today’s fibre-optic internet. That means it might not be too difficult to integrate the tech into existing infrastructure.
“[I]t is hoped that such fibres can enable practical high data-rate transmission in the near-term, contributing to the realization of the backbone communications system necessary for the spread of new communication services beyond 5G,” they write in their paper.
