    China's ultra-high-speed, ultra-large-capacity ultra-long-distance optical fiber transmission basic research has set a new record, for the first time to achieve an ordinary single-mode fiber transmission distance of more than 80 kilometers
    when the total transmission capacity reaches 100.
    23Tb/s (equivalent to 1.
    201 billion pairs of people talking simultaneously on one fiber).

    According to industry authoritative predictions, by 2030, global network data traffic and per capita network data traffic will increase by 1,000 times compared with 2010, and the optical transmission network as the foundation of the Internet and communication network will continue to face the pressure of carrying massive data, and network expansion has become imperative
    。 This time, for the first time in China, an ordinary single-mode fiber has been realized in the C+L band with 375 channels and 267.
    27Gb/s ultra-large capacity ultra-dense wavelength division multiplexing transmission transmission of 80 kilometers, realizing the breakthrough of China's optical fiber transmission experiment in the important technical index of capacity, and promoting China to enter the global forefront
    of transmission capacity experiment breakthrough of 100T.

    While successfully creating a new record of optical transmission in China and promoting the breakthrough of optical transmission technology in China, this three-super experiment effectively solves the key technical problems of ultra-high-speed and high-spectral efficiency ultra-long-distance transmission system such as "high-order modulation, high-spectral efficiency realization, and nonlinear effect suppression", lays a technical foundation for the practical application of ultra-high-speed ultra-dense wavelength division multiplexing and ultra-long-distance transmission, which will provide necessary core technology reserves for the construction of the national next-generation network, and will also provide strong support for the national broadband strategy and the promotion of information consumption

    This project is led by Wuhan Research Institute of Posts and Telecommunications, and the national 973 project "Basic Research on Ultra-high-speed, ultra-large-capacity ultra-long-distance optical fiber transmission"
    jointly participated by Huazhong University of Science and Technology, Fudan University, Beijing University of Posts and Telecommunications, and Xidian University.
