Altibox joins Verena subsea cable delivering 512Tbps capacity between UK and Denmark, targeting North Sea congestion by 2028.

Context

Norwegian operator Altibox has joined the Verena subsea cable project. The system will span 630km across the North Sea, connecting Scarborough in the UK with Esbjerg in Denmark. Altibox confirmed its participation in the project. The system forms part of its long-term infrastructure strategy to expand international reach. Verena will deploy 16 fibre pairs with a total design capacity of 512Tbps. This will significantly increase available bandwidth between the UK and the Nordics. The system is scheduled to enter service in the fourth quarter of 2028.

Evidence

Pending intelligence enrichment.

Analysis

The cable will land at a new site in Scarborough . No major subsea systems currently terminate there. Existing UK-Nordic routes rely on more northern landing points. Altibox is working with delivery and technology partners across the supply chain. The project also builds on earlier development linked to Woodstock Cable. Verena reflects a structural shift in North Sea connectivity. Capacity is no longer growing fast enough to keep pace with demand. Existing routes face concentration risk and limited expansion space. A 512Tbps system with a new landing point directly addresses this constraint. It introduces route diversity and reduces dependence on established hubs. This strengthens resilience against outages and traffic bottlenecks.
