We're in for an information revolution.

 

Engineers in Japan just shattered the world record for the fastest internet speed, achieving a data transmission rate of 319 Terabits per second (Tb/s), according to a paper presented at the International Conference on Optical Fiber Communications in June. The new record was made on a line of fibers more than 1,864 miles (3,000 km) long. And, crucially, it is compatible with modern-day cable infrastructure.

 

This could literally change everything.

The new data transfer method breaks signals up into various wavelengths

Note well: we can't stress enough how fast this transmission speed is. It's nearly double the previous record of 178 Tb/s, which was set in 2020. And it's seven times the speed of the earlier record of 44.2 Tb/s, set with an experimental photonic chip. NASA itself uses a comparatively primitive speed of 400 Gb/s, and the new record soars impossibly high above what ordinary consumers can use (the fastest of which maxes out at 10 Gb/s for home internet connections).

 

As if there's no limit to this monumental achievement, the record was accomplished with fiber optic infrastructure that already exists (but with a few advanced add-ons). 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....
