U.S. and Dutch scientists successfully achieved a data transfer rate of 255TB per second in a new type of fiber, a result that is 21 times more efficient than current commercial fiber.
Beijing time October 28 news, according to a physicist organization website reports, researchers from Eindhoven University of Technology in the Netherlands (TU/e) and the United States University of Central Florida (CREOL) recently published in the "Nature - Optics" magazine The article reports on an important technological development in the field of optical fiber communications. They successfully achieved a data transfer rate of 255TB per second in a new type of optical fiber. This result is 21 times more efficient than that of current commercial optical fibers. . The emergence of this technology may greatly increase the efficiency of optical transmission, thereby alleviating the crisis caused by tight bandwidth resources.
With the popularity of the Internet and the ever-increasing number of data centers, the demand for communication bandwidth in society is increasing day by day and will continue to grow exponentially. To transmit more data under the existing fiber optic system, one solution is to increase the strength of the transmitted signal, thereby helping to overcome the signal loss caused by the glass material used to manufacture the optical fiber itself. However, doing so will bring about unnecessary photon nonlinear effects, thus limiting the amount of information that the receiving end can interpret.
The research team from the Eindhoven University of Technology in the Netherlands and the University of Central Florida in the United States was led by Dr. Chigo Okonkwo and led by Dr. Rodrigo Amezcua Correa. . The former is an assistant professor in the Optoelectronics Communication Group at Eindhoven University of Technology, and the latter is an assistant professor of research in microstructured optics at the University of Central Florida. In their published paper, the research team elaborated on the potential of this latest technology to increase the data transmission rate, thereby reducing the crisis caused by insufficient bandwidth.
This new type of fiber has seven different cores for signal transmission, not just one in the most advanced fiber optics. It is like turning a one-lane road into a seven-lane road. At the same time, they also introduced two additional vertical channels for data transmission - it's like having three cars running in the same lane. Through the combination of these two methods, the research team successfully achieved a transmission rate of about 255TB per second, which is almost 20 times faster than the current optical transmission efficiency (4~8TB/s).
Dr. Chigo Okonwa said: "This fiber does not exceed 200 microns in diameter, and it will occupy no more space than existing fiber products. The advent of this technology will enable the achievement of PT-level transmission efficiency, and this It is one of the projects in the European Commission’s 'Vision 2020' research project. The results of this study also prove the importance of the research work carried out in Europe, especially in the field of optical fiber transmission at the University of Eindhoven and other high-level universities. Important work."
