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.
WatchRebecca Smith, Brodie Gage, and Dino DiPerna reflect on OFC 2026 and discuss how optical innovations are taking center stage in the AI Era. They share Ciena’s R&D approach that helps operators and hyperscalers build, scale, and prepare networks for AI – inside the data center and beyond.
ListenThis white paper, developed in collaboration between Ciena and Microsoft, explores how zero-trust optical design can deliver resilient metro connectivity. Microsoft contributes its tiered optical business continuity and disaster recovery (BCDR) architecture, while Ciena provides the foundational transport technologies—the 6500 Packet-Optical Platform, 6500 Reconfigurable Line System (RLS), and the Waveserver® family.
