At a Glance
Our compact 50 cm model simulates a 1,000 km satellite link with bidirectional, real-time data transmission at 10 Gbit/s. This demonstration reveals the system’s potential for stable, high-performance communication in aerospace applications through in-parallel data transmission of four spatially distributed channels in different wavelengths for the uplink.
Applications
Fraunhofer HHI‘s optical antenna systems serve as over-the-air bridges for classical and quantum-based optical communication, ideal for:
