Polar Connect, a proposed subsea fiber-optic cable linking Europe, North America and East Asia through the central Arctic near the North Pole, aims to provide an alternative to existing Europe–Asia data routes. Its backers target service in 2030, with seabed surveys, specialized vessels and access for repairs central to the project’s timetable and operation.
The initiative is driven by Nordic national research and education networks and NORDUnet, with partners including the Swedish Polar Research Secretariat and GlobalConnect. GlobalConnect says the Arctic crossing would shorten data routes, reduce latency and improve resilience by adding a geographically separate connection.
Polar Connect’s white paper identifies existing Europe–Asia routes through the Red Sea, Russia and the United States. The northern proposal is intended to reduce reliance on those corridors.
Subsea cables carry the overwhelming majority of international data exchanges. Red Sea disruptions have illustrated how conflict can complicate repairs. In March 2024, cable operator Seacom said obtaining repair permits could take up to eight weeks and warned that regional unrest could affect its repair schedule.
Surveying and vessels shape the timetable
An earlier Swedish Polar Research Secretariat study favored a route through the western part of the central Arctic Ocean, close to the North Pole. The preliminary recommendation said seabed data were unavailable for large parts of the route and that profiling campaigns were needed before a final route could be selected and a cable ordered.
In a December 29, 2025 announcement, GlobalConnect said the Swedish icebreaker Oden had begun mapping the seabed during the summer of 2025. Approximately 45% of the route had been mapped by November 2025, the company said, with a second expedition scheduled for 2026.
GlobalConnect also announced a €5 million grant from the European Union’s Connecting Europe Facility. It said the next preparatory phase, Polar Connect Step 2, would include further route studies, environmental assessment, identification of landing points and development of repair and maintenance scenarios.
The earlier Swedish Polar Research Secretariat study called for at least two powerful icebreakers and a vessel adapted to lay cable in Arctic conditions. GlobalConnect’s December 2025 announcement said deployment would require a new heavy icebreaker and that Sweden had not yet committed to funding it.
The earlier study described 2030 as a possible cable-laying year, conditional on seabed profiling and vessel availability. GlobalConnect’s later announcement used 2030 as its service target.
Ice can delay repairs
Alan Mauldin, a research director at cable-industry research firm TeleGeography, said ice damage could leave an Arctic cable inaccessible for repair until summer. Mauldin and telecom-capacity broker Roderick Beck identified expensive repairs and potentially lengthy outages as obstacles to an Arctic cable’s commercial viability.
Quintillion’s Alaska network provides an example of those access constraints. The company said its cable broke on June 11, 2023, in an ice-scouring event about 55 kilometers north of Oliktok Point in the Beaufort Sea. It said sea ice prevented repair vessels from reaching the site. In September 2023, GCI announced that repairs were complete, 14 weeks after the break.
After another incident near Oliktok Point in January 2025, Quintillion announced a successful repair on September 2, 2025, while noting that partner internet providers still had reconfiguration and activation work to complete before full restoration to end users. The company subsequently said repairs and deeper burial were complete and all connected providers had restored service to affected communities.
