A Chinese research group has developed a transmission system integrating fiber optic and super-fast wireless network connections. According to reports, the system achieves a transmission bandwidth 10 times higher than the speed of the 5G network.
This speed has set a new world record for data transmission speed. The research results were published on February 19 in the journal Nature.
The research team including Peking University, Pengcheng Laboratory, Shanghai University of Science and Technology and China National Center for Optoelectronic Innovation has developed a converging transmission system, reaching a channel speed of 512 Gbps (512 gigabits/second) via fiber optic cable and 400 Gbps via wireless network.
For easy visualization, the actual speed with home fiber optic networks today is about 100-300 Mbps; 512 Gbps is 5,120 times faster than 100 Mbps transmission. More simply, if you watch 2K quality movies equivalent to the speed of a motorbike running on the street, then 512 Gbps is like a 55,000-lane highway.
Mr. Wang Jingjun, at Peking University, said that the new system supports two modes of transmission via both fiber optic and wireless networks, according to Xinhua News Agency on February 20.
The results of large-scale user access testing show that the system supports 8K real-time video multi-channel access on 86 channels. Achieving 10 times higher transmission bandwidth than the highest 5G speed today.
Mr. Wang said that the new system has great application potential, laying the foundation for a generation of ultra-wide, high-speed data transmission integrated between fiber optic and wireless, opening up the foundation for 6G infrastructure and ultra-large data applications in the future.
