A data rate of data transfer by fiber-optical cable has been set

Researchers from the Danish Technical University set a data speed record for a single fiber-optic cable: the throughput of the experimental network reached 43 TBIT/s.

The previous record was set by employees of the Karlsruhe Institute of Technology in Germany in 2011. Then the data was sent at at a speed of 26 tbit/s. Thus, the current achievement exceeds the previous result by about 1.7 times.

The capacity of 43 Tbit/s corresponds to the possibility of transmission of approximately 5.5 TB of data every second. That is, the contents of a rigid disk with a capacity of 1 TB can be sent in approximately the fifth fraction of a second, and only 0.2 milliseconds will go to the file size of 1 GB.

Currently, the fastest commercial data network using the only fiber-optic cable operates at speeds of up to 100 Gb/s. The Institute of Electronics and Electrical Engineers (IEEE) is considering the possibility of introducing a standard for the next generation Ethernet networks at a speed of 400 Gb/s and 1 tbits/s. The second option is likely to be unusual due to the high cost of equipment. One way or another, but the new standard will be ratified no earlier than 2017.
