The researchers at Japan's National Institute for Information and Communication Technology have set a new world record for internet speed after they were able to transfer data at a rate of 319 Terabits per second.

The previous fastest data transfer-rate record was 179Tbps by a  group of Japanese and British researchers in August of 2020.

Scientists were able to successfully transfer the data for more than 1,864 miles, i.e. more than 3,000 km without any speed drop through an advanced optical fiber pipeline.

The groundbreaking test can be looked at as a revolutionary milestone in the field of Information Technology.

The crucial part of the research is that this is compatible with modern-day cable infrastructure.

NASA's staggering speed of 400Gb/s looks primitive in from of this mind-boggling speed. 

 The research team used four "cores", which are glass tubes housed within the fibers that transmit the data, instead of the conventional standard core. The signals are then broken down into several wavelengths sent at the same time, employing a technique known as wavelength-division multiplexing (WDM). To carry more data, the researchers used a rarely-employed third "band", extending the distance via several optical amplification technologies.
