The rapid growth of AI, cloud and edge computing is placing unprecedented pressure on both data center and fiber infrastructure. As digital ecosystems scale, traditional network designs struggle to meet rising demands for resilience, efficiency and low‑latency performance. The increasing interdependence between telecom networks and data centers is exposing architectural and operational constraints that limit scalability. Without rethinking how facilities and fiber infrastructure are integrated, operators risk creating bottlenecks that slow deployment and increase cost. Addressing these challenges is critical to supporting Europe’s next generation of digital services.

In this discussion, Stephan Rettenberger will join a panel of industry experts to examine how telecom and data center architectures are converging to meet hyperscale demands. They will explore approaches such as PON‑enabled resilience and the operational and governance models required to scale fiber deployment across complex, multi‑site programs. The panel will also consider how operators balance speed, efficiency and reliability as infrastructure footprints expand. Attendees will gain practical insight into the technologies and strategies needed to build resilient, scalable and future‑ready digital infrastructure.
