The new Internet speed record twice as fast as the old one


Everyone wants faster internet speeds. Even people who already have broadband connections want faster Internet access, including corporate employees and IT professionals. More speed is what they need, or at least what they would strongly prefer, because the faster data is transmitted between two devices, the faster decisions can be made and actions taken. In the Darwinian digital economy, slow internet speeds are only for latecomers and hikers!

So how fast is it? Some might say that the average US internet speed of 99.3 Mbps, measured earlier this year by, is more than enough, while a company with a large workforce and growing numbers connected devices and peripheral networks would need significantly more bandwidth.

For those who think their internet will never be fast enough, there is good news. Japanese engineers broke the previous world record for the fastest Internet speed, achieving data transmission rates of 319 terabits per second, nearly double the 178 Tbps mark set a year earlier.

Here’s how they did it, as described by Kristin Houser of Freethink:

To break the record for the fastest Internet speed, researchers at the Japan National Institute of Information and Communications Technology developed an experimental optical fiber with four cores, instead of just one.

They then combined their fiber with a laser that triggered pulses at different wavelengths and multiple signal amplification techniques. This allowed them to transmit data over a distance of over 1,800 miles at 319 Tb / s.

If you are ready to hook up this flamethrower to your corporate network, you are advised to curb your enthusiasm as the “laser and amplifiers used to beat the fastest internet speed record don’t come cheap”, Houser writing.

However, all is not lost for you dreamers. The experimental quad-core optical fiber used to set the latest speed record matches the standard 0.125mm outer diameter currently used for single-core fibers used today for fiber-optic internet service. This could speed up the implementation as there would be no need to replace an existing physical infrastructure.

“The standard cladding diameter, quad-core optical fiber can be cabled with existing equipment, and it is hoped that these fibers can enable convenient high-speed data transmission in the short term,” the researchers said in their report. published paper.

Anyone can guess how the researchers define “short term,” but in the long term, these quad-core optical fibers could be part of the network backbone needed to power the digital economy after 5G. And driving that economy will be automation, connected vehicles, connected offices and homes, connected public infrastructure, media streaming, augmented reality and virtual reality technologies, and devices such as personal drones and industrial. These technologies require backbone networks for real-time data transmission to ensure security and optimal performance.

For enterprise IT professionals, exponential increases in data transmission speeds are always welcome. While the speed achieved by the Japanese team today may be out of reach for the average corporate network, the trend is in the right direction. This means that there will always be sufficient backbone bandwidth to meet the growing needs brought about by new technologies.
