Japanese Researchers set a new world record for the fastest internet speed at 319 Terabits per second.
Researchers from Japan’s National Institute for Information and Communications Technology led by Benjamin J. Puttnam successfully achieved a new world record for the fastest internet speed. According to a paper presented last June at the International Conference on Optical Fiber Communications, the researchers achieved a data transmission rate of 319Tb/s.

The new data transmission method breaks signals into multiple wavelengths to achieve a high transmission rate
Puttnam’s team constructed a transmission system that entirely utilizes wavelength division multiplexing technology. This system involves four cores — glass tubes placed inside the fibers responsible for transmitting data. It combines various amplifier technologies to achieve the said data transmission rate over a distance of 3,001km.
The research team’s system starts its transmission process using a 552-channel comb laser that is fired at different wavelengths. Then, dual-polarization modulation takes place to generate a number of signal sequences. Each of the signal sequences is then directed into the four cores inside the optical fibers.
Through this system, the data transmitted moves through an optical fiber with a length of 70km. Along the transmission, the data will hit optical amplifiers, thus boosting the signal as it travels.
Japan’s new data transmission technology is a data infrastructure revolution
After the transmission process mentioned above, signal sequences will travel into another optical fiber segment before the entire process repeats. This method allows the researchers to send data over a distance of 3,001km.
Notably, the four-core optical fiber has a diameter that is the same as the conventional single-core fiber. This means that the researchers integrated the new data transmission method into the existing infrastructure. Such is much simpler than doing technological overhauls to the societal information systems.
The integration of the new and existing data transmission infrastructure is what makes the new world record for internet speed shine. The reason is that the researchers were able to create a novel engineering method that can integrate into the fiber-optic infrastructure of today with only minimal effort.
