Skagenfiber West

Overview

Skagenfiber West is a submarine cable system spanning approximately 170 kilometers across the Skagerrak strait, directly connecting Denmark and Norway. Entering service in 2020, this cable provides a vital telecommunications link between the two neighboring countries. Owned and operated by Altibox, a Norwegian broadband and fiber provider, Skagenfiber West is designed to deliver reliable and low-latency connectivity, supporting both residential and business needs in the region. Its relatively short length and strategic placement make it an important component of the broader network infrastructure in Scandinavia.

The Skagerrak strait, which the cable traverses, is a key maritime corridor connecting the North Sea to the Baltic Sea. By bridging this body of water, Skagenfiber West enhances regional connectivity and serves as a robust alternative to terrestrial routes. Its deployment underscores the importance of cross-border digital infrastructure in fostering economic and social ties between Denmark and Norway.

Route and Landings

Skagenfiber West connects Hirtshals in Denmark to Larvik in Norway, two coastal towns strategically located to minimize the cable’s length while maximizing its utility. Hirtshals, situated on the northern tip of the Jutland peninsula, faces the Skagerrak strait and is a hub for maritime and telecommunications activities. Larvik, on the Norwegian side, is located on the western shore of the Oslofjord in Vestfold county, a region with strong economic and logistical ties to Denmark.

The cable’s route across the Skagerrak strait takes advantage of the relatively narrow stretch of sea separating the two countries. This direct path ensures lower latency and reduced transmission distances compared to alternative routes. The choice of Hirtshals and Larvik as landing points reflects their strategic importance as gateways for international connectivity, as well as their proximity to existing terrestrial networks in both countries. This alignment allows Skagenfiber West to integrate seamlessly into the broader Scandinavian telecommunications infrastructure.

Ownership and History

Skagenfiber West is wholly owned by Altibox, a Norwegian provider specializing in fiber-based broadband and communications services. Altibox operates extensively across Norway, serving both residential and business markets with high-speed internet and related services. The cable’s launch in 2020 marked an important milestone in Altibox’s efforts to enhance cross-border connectivity between Norway and Denmark.

The deployment of Skagenfiber West aligns with a broader trend of strengthening regional telecommunications infrastructure in Scandinavia. By focusing on a direct, short-distance link across the Skagerrak, Altibox has positioned the cable as a complementary system to other regional and transatlantic cables. This includes larger systems such as Havfrue/AEC-2, which also connects Denmark and Norway but spans much greater distances. Skagenfiber West’s targeted design reflects its role as a dedicated bilateral connection, emphasizing reliability and performance for users in both countries.

What Our Measurements Show

Our live monitoring of Skagenfiber West has yielded consistent performance metrics that highlight the cable’s efficiency. Over the past 60 days, 217 measured corridors have shown an average round-trip time (RTT) of 26 milliseconds, with the best recorded RTT being 19 milliseconds. These figures are in line with expectations for a cable of this length, confirming its role as a low-latency link between Denmark and Norway.

The cable’s short physical distance of 170 kilometers contributes directly to its performance, as shorter routes typically experience less signal degradation and latency. The Skagerrak strait’s relatively calm and shallow waters also facilitate stable operations and maintenance, further enhancing the cable’s reliability. Skagenfiber West’s performance metrics underscore its importance as a high-quality connection for both residential and business users, complementing longer and more complex systems in the region.
