UWB-SDM Data-Plane Network Architecture for Scalable and Adaptive 6G Transport

This paper presents a flexible data plane architecture designed to optimize switching and resource allocation in optical networks. By enabling multi-level switching—spanning full fiber, spectral band, and wavelength levels— the architecture demonstrates adaptability to varying traffic demands across different network segments or in end-to-end configurations. Its modular structure supports the integration of Ultra-Wide Band (UWB) and Spatial Division Multiplexing (SDM) technologies, enabling efficient use of spectral and spatial resources. This study explores how the proposed architecture increases network flexibility and scalability, particularly in high-capacity scenarios, and provides a scalable foundation for next-generation optical transport systems.
