As digital infrastructure evolves, seamless end-to-end transmission between fibre-optic and wireless systems has remained a technical challenge due to differences in signal architecture and hardware design. These constraints have limited compatibility and performance within unified network environments. The newly developed platform overcomes these barriers by enabling high-speed transmission across both media within a single infrastructure.

According to China Daily, a partner of TV BRICS, the research team reported single-channel transmission speeds of 512 Gbps over optical fibre and 400 Gbps over wireless links. According to Wang Xingjun, a corresponding author of the study at Peking University, the dual-mode system enhances anti-interference capacity while mitigating bandwidth constraints and noise accumulation.

In large-scale simulation tests replicating 6G user access scenarios, the platform supported real-time 8K video streaming across 86 channels simultaneously. The demonstrated transmission bandwidth exceeded that of current 5G standards by more than tenfold, underscoring its capacity to handle ultra-high data loads in future network environments.

Beyond record speeds, the architecture delivers competitive performance in energy efficiency, cost optimisation and scalability. Its fully optical framework enables compatibility with existing fibre infrastructure, supporting deeper integration between mobile access and optical backbone networks. 

Researchers indicate that the system holds strong potential for deployment in 6G base stations and wireless data centres, contributing to the development of next-generation ultra-broadband communication ecosystems.
