Summary
As AI-driven workloads and data center interconnect traffic accelerate, optical networks are facing unprecedented pressure to scale. While 800G represents the next step in optical evolution, deploying it effectively requires the right approach. Moving to 800G is not simply a matter of faster optics, it requires careful consideration of spectrum constraints, existing infrastructure, and long-term architectural flexibility.
This seminar explores the real-world considerations of migrating to 800G in DWDM and OTN environments. Attendees will learn why 800G does not inherently increase fibre capacity, how to navigate upgrades within existing brownfield networks, and what practical migration strategies are available, including flex-grid architectures, L-band expansion, and phased deployment models. The session also examines the growing impact of optical component constraints and how modern, modular DWDM platforms can help operators scale efficiently while avoiding costly network redesigns.
