Arctic Way: Planned Submarine Cable Connecting Norway's Arctic Regions
The Arctic Way is a planned submarine cable system designed to enhance connectivity across Norway's Arctic regions. Owned by Space Norway, the cable is expected to be ready for service in 2028, though it is not yet operational. With landing points in
Bodø,
Fauske,
Longyearbyen, and
Olonkinbyen, the cable will serve as a critical infrastructure for improving telecommunications in remote areas of Norway, including the Svalbard archipelago.
What makes the Arctic Way particularly interesting is its focus on connecting some of the northernmost inhabited locations on Earth, including Longyearbyen and Olonkinbyen. These areas face unique challenges in maintaining reliable connectivity due to their extreme geographic and climatic conditions. However, many technical details about the cable, such as its design capacity, fiber pair count, and supplier, have not yet been disclosed, leaving some aspects of its future capabilities uncertain.

Route
The Arctic Way will span 2568 km, connecting four landing points in Norway: Bodø and Fauske on the mainland, and Longyearbyen and Olonkinbyen in the Svalbard archipelago. Bodø and Fauske are located in Nordland County, which is known for its rugged coastline and proximity to the Arctic Circle. Longyearbyen, the administrative center of Svalbard, and Olonkinbyen, a settlement on Jan Mayen Island, are among the most remote locations globally. The cable's route reflects a strategic effort to improve connectivity in these isolated regions.
Why it was built and what it carries
The Arctic Way is being developed to address the growing need for reliable and high-speed telecommunications in Norway's Arctic regions. These areas are critical for scientific research, environmental monitoring, and defense operations, but their remote location poses significant challenges for connectivity. The cable will likely support internet, data transmission, and potentially specialized services for research and government operations. However, without public disclosure of its design capacity and fiber pair count, the full extent of its capabilities remains unclear.
History: what can be established
The Arctic Way is slated to be ready for service in 2028, according to GeoCables data. No conflicting dates have been identified in publicly available industry sources, suggesting that this timeline is consistent with current planning. The cable is part of Space Norway's broader efforts to enhance Arctic communications, but detailed milestones in its development, such as supplier selection or construction progress, have not been disclosed.
Capacity and technology
Publicly available information does not include specifics about the Arctic Way's design capacity, fiber pair count, or the technology it will employ. Without operator documentation, these details cannot be reliably stated. It is likely that the cable will use modern submarine cable technologies, such as wavelength-division multiplexing (WDM), to maximize capacity, but attributing this without confirmation would be speculative.
Latency: the physics
The computed one-way light propagation latency for the Arctic Way's 2568 km wet segment is approximately 12.6 milliseconds, with a theoretical round-trip time (RTT) floor of 25.2 milliseconds. This calculation assumes light traveling at 200,000 to 204,000 km/s in optical fiber. Real-world RTT, however, will be higher due to additional factors such as land-based network segments, terminal equipment delays, and routing inefficiencies. As the cable is not yet operational, no live measurements of latency are available.
Redundancy: what happens if it breaks
If the Arctic Way experiences a failure, redundancy will depend on alternative cables in the region. Bodø is served by the
Bodo-Rost Cable and the
Polar Circle Cable, while Longyearbyen has connections via the
Longyearbyen-Ny-Ålesund cable and the
Svalbard Undersea Cable System. These existing cables could provide backup connectivity, although they may not fully replicate the Arctic Way's planned capacity or route. Repairing submarine cables in Arctic waters is logistically challenging due to harsh weather conditions and limited access, which could prolong downtime.
Bottom line
- The Arctic Way is a planned submarine cable connecting Norway's mainland and Arctic regions, expected to be ready for service in 2028.
- Owned by Space Norway, the cable will land in Bodø, Fauske, Longyearbyen, and Olonkinbyen.
- Its design capacity, fiber pair count, supplier, and technology have not been publicly disclosed.
- Computed latency for the wet segment is approximately 12.6 ms one-way, but real-world RTT will be higher.
- Redundancy will rely on existing cables in Bodø and Longyearbyen, though repair logistics in Arctic waters are challenging.
