Eurofiber has launched data centre connectivity services in Germany, linking facilities in six cities on a single Wavelength Division Multiplexing platform. Berlin, Düsseldorf, Frankfurt, Hamburg, Munich and Stuttgart form the initial footprint.

The Dutch infrastructure operator will build the offer mainly on fibre from NGN Fiber Network, a company in which it holds a stake. That detail matters for practitioners. Eurofiber is monetising an equity position rather than leasing third-party capacity at market rates, which shortens delivery times and protects margin on WDM circuits.

What does the service actually deliver?

WDM lets operators push multiple light wavelengths down one fibre pair, so each strand carries many separate high-capacity channels. For enterprise buyers, the practical outcome is simple: large volumes of data move between data centres quickly and reliably, on capacity they can scale.

Eurofiber positions the service against four workloads:

• Cloud service access and inter-cloud data transfer
• AI training and inference traffic between compute sites
• Routine data backups
• Disaster recovery and resilience architectures

The company frames the launch as a response to demand. Businesses in Germany want more options for connecting data centres as cloud and AI workloads grow, and the six-city footprint gives them an alternative carrier in a market long dominated by incumbent wholesale providers.

Why Germany, and why now?

Eurofiber International Program Director Arian de Korte said demand for connectivity between data centres is growing steadily. He said: "In Germany, enterprises, cloud service providers and international network providers are increasingly using regional data centres to bring data and applications closer to their operations and users, maintain greater control over their data and strengthen their digital resilience."

De Korte added: "This supports their digital sovereignty and increases the need for reliable interconnection between these facilities."

The sovereignty argument carries real commercial weight in Germany. Enterprise and public sector buyers there face sustained regulatory and political pressure to keep data on domestic soil, which pushes workloads away from hyperscale hubs and toward regional facilities. Those regional sites are only useful if the fibre between them is dense, fast and redundant. Eurofiber is selling exactly that layer.

CCO Andrea Kraus made the value case explicit: "For customers, the value of regional data centres depends increasingly on how well those locations are connected." She continued: "They need the flexibility to scale capacity, move data quickly and build resilience across their digital infrastructure. By expanding our data centre connectivity services in Germany, we give organisations a stronger foundation for cloud, AI and other data-intensive applications."

Note the boundary between fact and marketing. The six cities, the NGN Fiber Network dependency and the WDM technology are confirmed deployment facts. Claims that the service "strengthens digital resilience" or "supports sovereignty" are vendor positioning, though here they align with a genuine, measurable shift of German workloads into regional facilities.

A pattern, not a one-off

The launch fits Eurofiber's broader German push. The operator recently signed a fibre deal with Pÿur in Berlin to extend network reach, and it has partnered with Quantum Bridge and Juniper on quantum-based security for its infrastructure. Each move adds a layer: access fibre, security, and now data centre interconnect.

For carriers and enterprises, the immediate effect is a stronger competitive field in German metropolitan connectivity. The longer test is whether Eurofiber converts its six-city WDM footprint into sustained enterprise contracts as AI-driven traffic between regional data centres keeps climbing.
