Counted: other international cables landing in the same country (domestic cables between points of one country are not a way out), other cables at landing points within 50 km, and whether the country has land links. Not counted: cable capacity, operator contracts and satellite. Use as a first look at dependence, not as a statement of what would happen.

About the IOEMA-1 Cable System

Overview

IOEMA-1 is a submarine cable system that connects seven landing points across five countries in Western Europe: Denmark, Germany, the Netherlands, Norway, and the United Kingdom. This regional cable plays a critical role in enhancing connectivity and data exchange across these nations. While the exact build date, operational status, and capacity of IOEMA-1 remain undisclosed, its geographical reach and strategic landings underscore its importance for regional telecommunications infrastructure.

The cable supports robust interconnectivity between key economic and technological hubs in Europe, contributing to the resilience and diversity of the region's internet infrastructure. By linking multiple countries, IOEMA-1 facilitates seamless data transmission and strengthens the digital backbone of Western Europe, which is vital for both domestic and international communications.

Route and Landings

IOEMA-1 spans the North Sea and the Skagerrak Strait, connecting coastal regions and inland hubs in Denmark, Germany, the Netherlands, Norway, and the United Kingdom. Its landing points are strategically distributed to serve major population centers and economic regions:

  • Blaabjerg, Denmark
  • Wilhelmshaven, Germany
  • Eemshaven, Netherlands
  • The Hague, Netherlands
  • Kristiansand, Norway
  • Dumpton Gap, United Kingdom
  • Leiston, United Kingdom

The route crosses important maritime zones, including the North Sea, which is a hub for submarine cable activity due to its proximity to densely populated and economically significant regions. The cable's landings in Blaabjerg and Kristiansand provide connectivity to Scandinavia, while its endpoints in the United Kingdom and the Netherlands enhance links to Western Europe's financial and technological centers. Wilhelmshaven and Eemshaven serve as critical nodes for Germany and the Netherlands, respectively, further solidifying the cable's role in regional data exchange.

Ownership and History

IOEMA-1 is operated by Telxius, a telecommunications infrastructure company and a subsidiary of Telefónica, one of Spain's largest telecommunications providers. Telxius specializes in managing submarine cables and other critical infrastructure, supporting Telefónica's operations across Europe and Latin America. The ownership structure reflects the strategic importance of IOEMA-1 in connecting Western European markets and ensuring reliable data transmission across the region.

Although specific historical details about the cable's construction and deployment are unavailable, its design and landing points suggest a focus on enhancing regional connectivity and providing alternative routes for data traffic. This is particularly important in a region where high-speed internet access and low-latency connections are essential for economic activities, technological innovation, and international collaboration.

What Our Measurements Show

Our live monitoring of IOEMA-1 reveals that the cable supports 276 measured corridors, demonstrating its extensive reach and integration into the broader European telecommunications network. The best recorded round-trip time (RTT) is 0 milliseconds, indicating the potential for extremely low-latency connections under optimal conditions. The average RTT across all corridors is 92 milliseconds, reflecting the cable's performance in real-world scenarios.

The cable's ability to maintain low latency across its routes is critical for applications requiring high-speed data transfer, such as financial transactions, cloud computing, and media streaming. By linking key landing points in Western Europe, IOEMA-1 plays a vital role in supporting the region's digital economy and ensuring the reliability of cross-border communications. The data collected from our probes highlights the cable's efficiency and its contribution to the overall resilience of Europe's internet infrastructure.
