Purpose and goal
The objective is to realize and validate a scalable 6G network architecture and/or topology by adapting both dense wavelength division multiplexing (DWDM) enabled multi-channel analog transceivers (e.g. 32CH) and dense space division multiplexing (DSDM) enabled fiber infrastructure (e.g. 12-core multi-core fiber (MCF)) for the field deployment of both centralized and distributed radio access networks (RAN).
Expected effects and result
The project will deliver validated 32‑channel analog transceivers by adapting conventional and photonic platforms and ecosystems. These will be integrated into a 6G testbed radio system as a proof‑of‑concept demonstrator of high performance and energy efficiency. Results include new signal processing, optical components, and system integration, reducing energy use and costs while improving 6G network robustness and competitiveness in optical communications.
Planned approach and implementation
The project is carried out in collaboration between industry and research, covering design, development, and integration of analog transceivers, signal processing, and photonic components. Activities include modelling, prototype development, and two proof‑of‑concept demonstrations, with testing over different fiber types. Results are validated in laboratory environments against relevant standards and iteratively optimized toward practical use in 6G networks.
