Adtran and Orange are collaborating on a lab trial of quantum key distribution (QKD) technology over an optical network. The trial featured Adtran’s FSP 3000 with OpenFabric technology for efficient encryption key distribution and optimized link performance. Leveraging a coherent 400Gbit/s DP-16QAM channel, the platform transported a QKD-secured data stream across two trusted nodes and three links, spanning 184km of standard, single-mode dark...
