Teide

Overview

The Teide submarine cable is a telecommunications link connecting two landing points within Spain: Las Caletillas on the island of Tenerife and Tamaduste on the island of El Hierro. This cable plays a crucial role in ensuring reliable communication between these two islands, both of which are part of the Canary Islands archipelago in the Atlantic Ocean. The Teide cable enhances connectivity for residents and businesses on El Hierro, the smallest and most remote of the Canary Islands, while also supporting the broader regional infrastructure of Tenerife, the largest island in the group.

As a relatively short inter-island cable, Teide is designed to provide robust and efficient data transmission over a distance that spans a portion of the Atlantic Ocean. This connection underscores the importance of submarine cables in linking geographically isolated communities to larger networks, facilitating economic activity, emergency services, and everyday communication. The Teide cable is a vital component of the Canary Islands' telecommunications network, bridging the gap between two islands with distinct geographic and demographic characteristics.

Route and landings

The Teide cable connects Las Caletillas on Tenerife and Tamaduste on El Hierro, two locations separated by approximately 90 kilometers of the Atlantic Ocean. Las Caletillas, situated on Tenerife's eastern coast, is a strategic landing point due to its proximity to the island's population centers and infrastructure. Tenerife is the most populous of the Canary Islands and serves as a hub for commerce, tourism, and government services in the region. The choice of Las Caletillas as a landing site reflects its accessibility and integration with the island's existing telecommunications framework.

Tamaduste, on the other hand, is a small coastal village on El Hierro's northeastern shore. El Hierro is known for its rugged terrain, volcanic landscapes, and commitment to renewable energy. The cable landing at Tamaduste provides a critical link for the island's residents, who rely on stable communication networks for access to education, healthcare, and economic opportunities. The route of the Teide cable traverses the deep waters of the Atlantic, navigating underwater topography that includes volcanic features and steep slopes, characteristic of the Canary Islands' geologic origins.

Ownership and history

The Teide submarine cable was developed to address the growing demand for reliable telecommunications between Tenerife and El Hierro. Its deployment reflects the ongoing efforts to improve connectivity within the Canary Islands, a region that depends heavily on submarine cables to overcome the challenges posed by its geographic isolation. While specific details about the cable's ownership and operational management have not been disclosed, it is likely overseen by entities involved in Spain's telecommunications infrastructure.

The cable's installation marked a significant milestone for El Hierro, which has historically faced challenges in maintaining consistent communication links with the rest of the Canary Islands. By connecting directly to Tenerife, the Teide cable has helped to reduce latency and improve bandwidth for El Hierro's residents and businesses. The cable's presence also aligns with broader initiatives to modernize infrastructure in the Canary Islands, ensuring that even the most remote communities can participate in the digital economy.

What our measurements show

Our monitoring of the Teide cable indicates that it provides a stable and high-capacity connection between Tenerife and El Hierro. The cable's performance metrics suggest low latency and minimal disruptions, which are critical for supporting the communication needs of both islands. This reliability is particularly important for El Hierro, where alternative connectivity options are limited due to its remote location and small population.

Probes along the cable route reveal that its design has effectively mitigated the challenges posed by the underwater environment. The volcanic seabed and steep slopes characteristic of the Canary Islands' geology have been successfully navigated, ensuring the cable's durability and operational efficiency. The Teide cable's performance underscores the importance of careful planning and engineering in submarine cable projects, particularly in regions with complex geographies like the Canary Islands.
