Speed of connection to the Network is often a painful issue for both regular users and some professional areas. Therefore, various researchers do not stop looking for ways to increase it. The Network Research Institute of the National Institute of Information and Communications Technology reported a new speed record.
Thanks to the multi-core fiber connection with a standard diameter of 0.125 mm, the researchers were able to achieve a data rate of 1.02 petabits per second. The team’s last attempt in March 2020 showed only 0.61 petabits.

That is, thanks to this technology, you can transmit 125 TB of data per second. For example, this speed can be used to broadcast 10 million channels with a resolution of 8K. And thanks to the use of existing technologies and maintaining standard cable sizes, it will potentially be less difficult to implement such.
Among the highlights of this experiment are the following:

1 petabit per second bandwidth is demonstrated in a standard sheath fiber using only 4 spatial channels;
broadband multiplexing technology with wavelength division allowed to create 801 parallel wavelength channels with a record optical bandwidth of 20 THz;
the demonstration is an important step toward the implementation of ultra-high-throughput optical channels with standard-diameter sheath fibers compatible with existing cable technologies shortly.

It is noted that this speed is one hundred thousand times greater than the best proposals available. However, in the real world, everything is much slower. According to the data of Speedtest, the median for the world’s “landline” in April this year is 63.5 Mbps download speed, and 27 Mbps upload. Among the leading countries are Singapore (207.6), Chile (200), Thailand (189.6), and Ukraine is ranked only 71st in the ranking with a speed of 49.8 Mbps. The slowest connections are in Turkmenistan (2.1), Cuba (1.9), and Afghanistan (1.8).
