Scientists have created a fiber with a record bandwidth


    Учёные создали оптоволокно с рекордной пропускной способностью

    Researchers from the Eindhoven University of Technology (TU / e) in the Netherlands, in collaboration with colleagues from the University of Central Florida (CREOL), published in the journal Nature Photonics reports about reaching a record high data rate – 255 terabits / second.

    Such a high rate was achieved by using a new type of optical fiber capable of transmitting information at a rate 21 times higher than those used in modern fiber communication networks. This type of fiber may help to overcome the looming shortage of bandwidth used today lines.

    In connection with the huge rise in popularity of various internet services and data centers requiring high-speed data links, traffic growth will continue exponentially.

    To transmit more information on existing optical fibers typically increase the transmitted power to compensate the attenuation over long distances. However, this leads to unwanted nonlinear distortions that plague accept the transmitted information.

    The great potential and possibilities of a new type of optical fiber in an article that appeared in the online version of the journal Nature Photonics, said Dr. Chigo Okonkwo, associate professor of TU / e, specializing in opto-electronic communications, as well as Rodrigo Amezcua Correa, governing in CREOL research in microstructured fibers.

    In their view, the development will contribute to mitigate the impending shortage of capacity backbone networks.

    The new seven-core fiber is used, conducting the light, whereas in the conventional optical fiber core is only one. The transition to the new technology can be represented as a single-lane road with the Congress on the seven-band high-speed highway.

    Furthermore, the scientists were able to add two more paths for transmission of light in one fiber, significantly increase the capacity of a single channel. It is the combination of these two methods to achieve target of 255 terabits / second.

    This is 20 times higher than the standard speed for today – from 4 to 8 terabit / s.

    Dr. Chigoev Okonvo: “Less than 200 microns in diameter – the new fiber does not require significantly increase the size of the cable. The results of our work will certainly make it possible to achieve bandwidth petabit per second – is the main goal of the seven-year research program of the European Commission “Horizon 2020″.

    The result also proves the key importance of cooperation of European researchers, in particular, and of the TU / e, with other famous teams around the world to work to increase the capacity of optical electronic data transmission systems.”
