SHEFA-2

Overview

SHEFA-2 is a submarine cable system spanning approximately 1,000 kilometers, connecting the Faroe Islands with the United Kingdom. Operational since 2008, it provides critical regional connectivity across the North Atlantic, linking the autonomous Danish territory to multiple landing points in the UK. This cable plays a vital role in supporting telecommunications and data traffic between the Faroe Islands and one of the most interconnected nations in the world. Its design and deployment reflect the strategic need for reliable, high-capacity communication infrastructure in this geographically distinct corridor.

Unlike intercontinental systems that serve broader global routes, SHEFA-2 is a regional cable focused on point-to-point connectivity. It facilitates data transmission for communities in both territories, bridging the Faroe Islands' limited network infrastructure with the UK's extensive cable ecosystem. This direct connection enhances digital access for the islands' population and supports industries reliant on stable and efficient communication links.

Route and Landings

SHEFA-2 begins its journey in Torshavn, the capital of the Faroe Islands, which serves as the cable's sole landing point in the territory. Torshavn is the largest settlement in the Faroe Islands and a hub for administrative and economic activity, making it a logical choice for the cable's landing. From there, the system crosses the North Atlantic, landing at six points along the UK coastline: Ayre of Cara, Banff, BP Clair Ridge, Glen Lyon, Maywick, and Sandwick.

The landing points in the United Kingdom are geographically diverse, spanning both mainland locations and offshore installations. For instance, BP Clair Ridge and Glen Lyon are associated with energy infrastructure in the North Sea, while Banff and Sandwick serve more traditional coastal communities. This distribution reflects the cable's dual role in supporting both industrial operations and residential connectivity. The route traverses waters known for their challenging conditions, requiring robust engineering to ensure reliability and performance.

Ownership and History

SHEFA-2 is owned and operated by Shefa, a single-owner entity rather than a consortium. This ownership model allows Shefa to maintain full control over the cable's operations, maintenance, and upgrades. The system was officially ready for service in 2008, marking a significant milestone in the Faroe Islands' telecommunications infrastructure. Since its deployment, SHEFA-2 has been a cornerstone of connectivity for the islands, complementing their limited cable network.

The Faroe Islands are served by just two submarine cables, making SHEFA-2 a crucial link to the outside world. Its 1,000-kilometer length places it among the longer regional systems, providing reliable connectivity to the UK, which boasts one of the world's most extensive cable networks. The UK’s infrastructure supports global data traffic, and SHEFA-2 integrates the Faroe Islands into this broader ecosystem, enabling faster and more efficient communication.

What Our Measurements Show

Our monitoring of SHEFA-2 reveals consistent performance across its three measured corridors. The cable achieves a best round-trip time (RTT) of 17 milliseconds, with an average RTT of 20 milliseconds. These latency figures indicate efficient data transmission, particularly for a regional system spanning 1,000 kilometers. Such performance is critical for supporting modern digital services, including internet access, cloud computing, and real-time applications.

The measurements highlight the cable's reliability in connecting the Faroe Islands to the UK, ensuring stable communication for both residential users and industrial operations. The low latency is particularly beneficial for the Faroe Islands, where limited connectivity options make high-quality links essential. This performance underscores SHEFA-2’s role as a vital infrastructure asset in the North Atlantic corridor, providing robust and dependable connectivity for the communities it serves.
