Researchers have reached a data transfer rate of 100 terabits / sec

I remember that the oldest Swedish woman has the fastest connection to the Network in the world. A 75-year-old grandmother can use all the advantages of broadband access, since her Internet connection is fast enough to take full advantage of the Global Network - 40 Gb / s is enough for any task. True, the average user can only dream of such a channel width. This woman is lucky - her son is Peter Lotberg, a Cisco employee. However, even such a high-speed connection is nothing compared to the achievements of two independent groups of researchers from the USA and Japan, who were able to set a new world record for data transfer speed - 100 terabits per second.

So far, such a record has been set in laboratory conditions, but it is clear that they will try to transfer such an achievement to commercial rails as quickly as possible. The first group of researchers representing NEC used well-known methods of "packing" data using laser beams of different spectra, with different amplitudes and phases of radiation. All this allows you to "pack" a huge amount of information, transmitting through a single fiber at high speed.

One of the developers, Dayou Qian, announced at a Los Angeles conference Optical Fiber Communications about data transmission at a speed of 101.7 terabits per second over a distance of 165 kilometers. His team achieved this result using 370 individual laser beams using the data “packaging” methods mentioned above. Each beam was strictly limited in spectrum, in addition, different polarities, phases and amplitudes of light waves were used to encode data packets.

At the same conference, Japanese Jun Sakaguchi, representing the Tokyo National Institute of Information and Communication Technologies, also spoke. The Japanese also reported on reaching the 100-terabit threshold, only a team of researchers from Japan used a different method of data transfer. The Japanese used a fiber optic core consisting of 7 separate fibers, each of which provided data transmission at a speed of 15.6 terabits per second. Thus, the total throughput of such a core is 109.2 terabits per second.

Researchers report that both methods are quite difficult to implement under normal conditions, and most likely, representatives of NEC believe that at first this method of data transfer will be used by large companies in data centers.
