China Achieves Breakthrough in Optical Communication and 6G Technology
Beijing (ANTARA) - A Chinese research team has developed a unified communication system linking fibre optic and wireless networks, setting a new world record in data transmission speed, according to a study published this week in the journal Nature.
The growing demand for computing power in AI data centres and the development of next-generation 6G wireless networks require high-speed, low-latency signal transmission across various scenarios.
However, differences in signal architecture and hardware between fibre optic communication systems and wireless communication systems have made it difficult to achieve high-speed, compatible end-to-end transmission between the two systems on the same infrastructure, posing a major challenge for high-speed telecommunications networks.
The research team, comprising Peking University, Peng Cheng Laboratory, ShanghaiTech University, and the National Optoelectronics Innovation Centre, developed a unified communication system that achieved single-channel signal transmission of 512 Gbps over fibre optic and 400 Gbps over wireless networks.
According to Wang Xingjun, one of the lead authors of the paper at Peking University, the new system supports dual-mode transmission over fibre optic and wireless networks, not only overcoming bandwidth limitations and noise accumulation but also enhancing anti-interference capabilities.
The team also simulated large-scale 6G user access scenarios, demonstrating real-time multi-channel 8K video access across 86 channels, with transmission bandwidth more than ten times that of current 5G standards.
In addition to enabling ultra-high-capacity communication, the system demonstrated excellent performance in terms of energy consumption, cost, and scalability for large-scale deployment.
The system's fully optical architecture enables seamless integration with existing optical networks, driving deep convergence between mobile access networks and fibre optic networks.
Wang noted that the new system holds significant deployment potential in scenarios such as 6G base stations and wireless data centres, and could reshape telecommunications system architecture, laying the foundation for next-generation high-speed, ultra-broadband integrated fibre optic-wireless communication.
