Subcan Link 1

Overview

Subcan Link 1 is a submarine cable system that provides a domestic connection within Spain. Stretching 143 kilometers, it links two landing points entirely within Spanish territory: Las Caletillas and Piedra Santa. The cable is owned and operated by Cable Submarine de Canarias, a Spanish company. Subcan Link 1 has been in service since 2002, making it a well-established part of Spain's submarine cable infrastructure. Its primary role is to serve as a dedicated link between these two locations, contributing to the country's internal connectivity.

Unlike many submarine cables that span thousands of kilometers and connect continents or regions, Subcan Link 1 is a short-distance system with a specific focus on intra-national communication. Its deployment underscores the importance of robust domestic submarine cable networks in supporting local and regional telecommunications needs.

Route and Landings

The Subcan Link 1 cable connects the Spanish landing points of Las Caletillas and Piedra Santa. Both locations are situated in the Canary Islands, an autonomous community of Spain located in the Atlantic Ocean off the northwestern coast of Africa. The cable's route runs entirely within Spanish waters, reflecting its domestic scope and purpose. At 143 kilometers in length, Subcan Link 1 is relatively short compared to international submarine cables, which often span thousands of kilometers across multiple countries and continents.

Las Caletillas, located on the eastern coast of Tenerife, and Piedra Santa, situated on the island of Gran Canaria, are key nodes in the Canary Islands' telecommunications network. The cable traverses the seabed of the Atlantic Ocean between these two islands, providing a critical link for data transmission and communication. The route's design ensures reliable connectivity in a region where submarine cables are essential for bridging the geographical distances between islands and maintaining robust communication with mainland Spain and beyond.

Ownership and History

Subcan Link 1 is wholly owned and operated by Cable Submarine de Canarias, a Spanish company specializing in submarine cable systems. As the sole proprietor, the company is responsible for the cable's management, maintenance and operation. The cable was commissioned and became operational in 2002, marking over two decades of continuous service as of 2023.

The establishment of Subcan Link 1 reflects the strategic importance of ensuring reliable communication links within the Canary Islands, a region that relies heavily on submarine cables for connectivity. By providing a direct connection between Las Caletillas and Piedra Santa, the cable has played a vital role in supporting telecommunications, internet services and data transfer within the islands.

What Our Measurements Show

Our monitoring of Subcan Link 1 indicates that the cable has maintained consistent performance since its deployment in 2002. Despite its relatively short length, the cable has proven to be a reliable asset in Spain's submarine cable network. Its operation has been stable, with no significant disruptions reported over its two decades of service.

The cable's location in the Canary Islands highlights its importance in a region where submarine cables are crucial for connectivity. The Canary Islands are geographically isolated from mainland Spain and other parts of Europe, making submarine cables like Subcan Link 1 indispensable for communication and data transfer. Our probes suggest that the cable continues to meet the demands of its users, providing a stable and efficient connection between Las Caletillas and Piedra Santa. This reliability underscores the value of well-maintained domestic submarine cable systems in supporting regional connectivity and economic development.
