Editor’s take: A team of researchers from the National Institute of Information and Communication Technology (NICT) in Japan have blown the old Internet speed record of 178 terabits a second out of the water. The new record? An eye-watering 319 terabits per second. It took some ingenuity and tweaking to get it working, but the good news is that the new fiber optics are compatible with existing equipment, meaning it might not be too difficult to retrofit existing lines.
To achieve this feat, the researchers (led by led by Benjamin J. Puttnam) built a transmission system that fully utilizes wavelength division multiplexing technology by combining different amplifier tech.
