1.6Tbps Quantum-Safe Communications

The shift toward quantum-safe communications is not optional—it is inevitable. Ciena’s WaveLogic 6 Extreme 1.6T quantum-safe encryption solution on the Waveserver platform was designed with this in mind, supporting QKD system interworking and NIST-certified PQC algorithms. It delivers an always-on, wire-speed encryption solution, without impacting performance or adding operational complexity, to ensure confidentiality as data moves between locations, devices, and applications.
