The Fraunhofer Heinrich-Hertz-Institut (HHI) has launched the HYPERCORE project, aimed at developing energy-efficient, secure, and high-performance communication infrastructure for the hyper-connected society. The project, funded by the German Federal Ministry of Education and Research (BMBF), focuses on optimizing metro and core networks, exploring a combination of all three physical dimensions (time, frequency, and space) for increasing transmission capacity. The project involves developing multiband transmission systems, coherent OTDR systems for network control, and expanding digital twin technology for optical communication networks. Field tests are planned for 2026 in Kiel and Berlin.
