The IOEMA project is establishing a state-of-the-art, AI-ready, high-capacity fiber optic connection between the five key Northern European markets. The Netherlands, Germany, the United Kingdom, Denmark, and Norway will be directly connected via a 1,600-kilometer repeatered subsea cable (further connectivity to France is under consideration). IOEMA is taking international tensions and security into account by fully armoring and protecting the subsea cable system over its entire length. IOEMA is also considering adding sensors to the system to make it the first SMART cable in Northern Europe. IOEMA is collaborating on this initiative with partners including Eurofiber, Arelion, Colt, EXA Infrastructure, Relined, Bulk, and EWE TEL.
The latest collaboration with Greenhouse Datacenters is driven in part by its strategic South Holland location, just 12 kilometers from where the subsea cable from the North Sea comes ashore in Scheveningen (Rotterdam/The Hague). The extensive presence of connectivity partners in Greenhouse’s data centers also plays a role, including AMS-IX, Lumen, Delta Fiber, Odido, and DCspine, in addition to IOEMA partners such as Eurofiber and Relined.

Greenhouse Datacenters CEO Ruben van der Zwan says the selection of Greenhouse as landing partner for the IOEMA subsea cable highlights the strategic importance of its data centers for the Dutch South Holland region and the Netherlands as a whole.
