Multi-Band Transmission is a communication technique that uses multiple frequency bands simultaneously to increase capacity and reliability. It is applied in wireless, satellite, and optical systems to enhance spectral efficiency. Adaptive allocation of frequency resources allows for improved performance in varying conditions. NEC Laboratories America investigates multi-band methods in the context of optical and 5G networks. The approach supports higher throughput and resilience in modern communication infrastructures.
GNPy advancements enable accurate and efficient modeling of multiband optical networks for digital twin applications. The developed solvers for Kerr nonlinearity and SRS have been validated through simulation and experimentally in C+L transmission, supporting real-world network planning, design, and performance optimization across disaggregated optical infrastructures.
