AI is not just driving demand for more network capacity. It is fundamentally changing what networks need to do. AI workloads introduce a traffic profile unlike anything cloud computing has required before, with massive east-west data flows, tightly synchronized compute clusters, and stringent requirements for low latency and deterministic performance.
For optical and fiber networks, the implications are significant. Metro, long-haul, and subsea infrastructure are all facing pressure as traffic growth is measured in multiples, not incremental percentages. Meanwhile, the industry is approaching physical limits in spectral efficiency, accelerating the shift toward multi-fiber architectures, new optical line systems, and automated operations.
This report examines how AI-driven demand is reshaping traffic patterns and network requirements, the role of coherent optics and pluggable technologies, the growing importance of data center interconnect, and the challenges of deploying optical infrastructure for the AI era.
