Jakarta, INTI - A research team from China has developed an integrated communication system that connects optical fiber and wireless networks, setting a new world record in data transmission speed, according to a study published in the journal Nature.
The system achieved single-channel signal transmission speeds of 512 Gbps through optical fiber and 400 Gbps via wireless networks.
The breakthrough was led by a joint team from Peking University, Peng Cheng Laboratory, ShanghaiTech University, and the National Optoelectronics Innovation Center.
Rising demand for high computing power in AI data centers and the advancement of 6G networks have intensified the need for ultra-high-speed, low-latency signal transmission across various scenarios.
Until now, differences in signal architecture and hardware between optical fiber and wireless systems have made it difficult to achieve seamless end-to-end high-speed transmission within a unified infrastructure.
Wang Xingjun, one of the lead authors from Peking University, explained that the new system supports dual-mode transmission across optical fiber and wireless networks. This approach overcomes bandwidth limitations, reduces noise accumulation, and enhances interference resistance.
Toward Scalable 6G and Next-Generation Telecom Architecture
The team also simulated large-scale 6G user access scenarios, demonstrating real-time multi-channel 8K video streaming across 86 channels with bandwidth exceeding ten times that of current 5G standards.
Beyond its massive capacity, the system also demonstrated strong performance in energy efficiency, cost effectiveness, and scalability for large-scale deployment.
Its fully optical architecture enables seamless integration with existing optical networks while promoting convergence between mobile access networks and fiber infrastructure.
Wang added that the system could potentially be deployed in 6G base stations and wireless data centers, reshaping next-generation telecommunications architecture toward ultra-high-speed, ultra-broadband integrated fiber-wireless communication.
Conclusion
China’s latest breakthrough marks a significant step toward next-generation telecommunications infrastructure. By merging fiber-optic and wireless systems into a unified architecture, the research not only sets a new data transmission record but also lays the groundwork for scalable 6G deployment, AI-driven data centers, and future ultra-high-speed digital ecosystems.
