Altibox Carrier confirmed that the Verena subsea cable project between the United Kingdom and Denmark has entered the delivery phase, with the contract now formally in force. The system will deliver a design capacity of 512 Tbps, positioning it as a major new high-capacity route across the North Sea and reinforcing connectivity between the UK and Nordic region.
The Verena cable will extend approximately 630 km (about 391 miles), linking Scarborough on England’s east coast to Esbjerg in Denmark. The system features 16 fiber pairs and is scheduled to be Ready-for-Service in Q4 2028. Altibox Carrier stated that the project aims to improve network resilience and route diversity for international traffic flows into Scandinavia, where demand for cloud, AI infrastructure, and data center interconnect capacity continues to rise.
A consortium of partners is supporting the deployment, including JTD Associates overseeing program management, Xtera contributing subsea engineering, Cecon Contracting leading marine installation using the Cecon Vigor vessel, and Pelagian handling route engineering and survey operations. Early engineering work and route studies have been completed, with marine survey activity expected to follow in the coming months.
- 512 Tbps total design capacity across 16 fiber pairs
- ~630 km subsea route between Scarborough (UK) and Esbjerg (Denmark)
- Ready-for-Service target: Q4 2028
- Focus on resilience and route diversity for UK–Nordic connectivity
- Partners include JTD Associates, Xtera, Cecon Contracting, and Pelagian
- Marine installation to be executed using the Cecon Vigor vessel
“International connectivity into the Nordics is entering a new phase of growth,” said Svein Arild Ims, CEO of Altibox Carrier. “Verena will play a critical role in supporting that demand by delivering a high-capacity, resilient route between Denmark and the UK.”
🌐 Analysis: The 16 fiber-pair, 512 Tbps design aligns with current subsea system architectures optimized for spatial division multiplexing (SDM). Compared to earlier generation North Sea systems, Verena significantly increases per-cable capacity while supporting evolving traffic patterns tied to AI workloads and east-west European data flows.
