Tverrlinken

Overview

Tverrlinken is a domestic submarine cable system in Norway, connecting four key coastal locations: Hemnesberget, Mo I Rana, Nesna and Utskarpen. The cable was commissioned in 2010 and is owned and operated by KystTele. Its deployment reflects the importance of robust digital infrastructure in Norway, a country characterized by its rugged terrain, deep fjords and dispersed coastal communities. Tverrlinken plays a vital role in linking these areas, providing reliable connectivity in a region where terrestrial alternatives are often impractical or cost-prohibitive.

Submarine cables like Tverrlinken are essential for ensuring high-speed communication and data transfer in geographically challenging areas. By connecting these four locations, the cable supports local economic activities, public services and everyday communications, contributing to the broader digital integration of Norway.

Route and Landings

The Tverrlinken submarine cable spans the coastal waters of Nordland County in northern Norway, connecting Hemnesberget, Mo I Rana, Nesna and Utskarpen. These locations are situated along the Helgeland coastline, a region known for its intricate network of fjords, islands and peninsulas. The cable's route crosses some of Norway's deep fjords, which are natural barriers to terrestrial infrastructure development. By traversing these underwater landscapes, Tverrlinken provides a direct and efficient link between these communities.

Hemnesberget, a small town on the Hemnes peninsula, serves as one of the cable's landing points. Mo I Rana, a larger industrial town and transport hub, is another critical node in the network. Nesna, located on the coast near the Arctic Circle, and Utskarpen, a village nestled within a fjord, complete the cable's landing points. Together, these locations represent a mix of industrial, residential and remote communities, all benefiting from enhanced connectivity provided by Tverrlinken.

Ownership and History

Tverrlinken is owned and operated by KystTele, a telecommunications provider specializing in submarine cable systems within Norway. The cable became operational in 2010, marking a significant step in improving regional connectivity in Nordland County. Its deployment aligns with Norway's broader strategy to enhance digital infrastructure in remote and coastal areas, ensuring that even sparsely populated regions have access to reliable communication networks.

The decision to establish Tverrlinken reflects the challenges of Norway's geography, where mountains, fjords and islands make terrestrial communication networks difficult to implement. Submarine cables like Tverrlinken are a practical solution, offering durability and efficiency in connecting dispersed communities. While no major upgrades or status changes have been reported since its commissioning, the cable remains an integral part of the local communication infrastructure.

What Our Measurements Show

Our monitoring of the Tverrlinken cable indicates stable performance across its operational lifespan. The cable's route through the Helgeland coastline's fjords and coastal waters presents unique environmental challenges, including variable seabed conditions and potential exposure to fishing activities. However, Tverrlinken appears to have been engineered to withstand these conditions, maintaining consistent connectivity between its landing points.

Probes show that the cable supports reliable data transfer rates suitable for the needs of the connected communities. The relatively short distances between the landing points reduce latency, ensuring efficient communication. Tverrlinken's performance highlights the effectiveness of submarine cables in addressing the connectivity needs of remote and coastal regions, particularly in a country like Norway, where natural barriers often limit terrestrial solutions.
