Est-Tet

Overview

The Est-Tet submarine cable is a 113-kilometre system that connects Morocco and Spain across the Strait of Gibraltar. Operational since 1994, it is one of the earliest undersea cables to link North Africa with the Iberian Peninsula. The cable plays a strategic role in connecting the telecommunications networks of the two regions, traversing one of the world's busiest maritime passages. Despite its relatively short length, Est-Tet has been a critical piece of infrastructure in the Morocco-Spain corridor for nearly three decades.

The Strait of Gibraltar, where the cable is laid, is a narrow waterway separating the Atlantic Ocean from the Mediterranean Sea. It also serves as a natural boundary between Europe and Africa. The Est-Tet cable leverages this geographic proximity to provide a direct and efficient undersea connection between the two continents. Its route reflects the historical and economic ties between Morocco and Spain, enhancing cross-border communication and data exchange.

Route and Landings

Est-Tet begins its route in Tétouan, a northern Moroccan city located near the Mediterranean coastline. Known for its historic medina and proximity to the Strait of Gibraltar, Tétouan serves as a key landing point for the cable on the African side. The city's location makes it an ideal gateway for telecommunications infrastructure linking Morocco to Europe.

On the European side, the cable lands in Estepona, a town on Spain's Costa del Sol in the Andalusia region. Estepona is situated along the southern coastline of Spain, making it a strategic landing point for cables crossing the Strait of Gibraltar. The town's location on the Mediterranean ensures a direct and efficient connection to Tétouan, with the cable spanning the shortest possible distance between the two continents.

The route of Est-Tet, though relatively short, crosses a highly significant maritime zone. The Strait of Gibraltar is not only a critical shipping lane but also a natural chokepoint for undersea cables linking Europe, Africa and beyond. By connecting Tétouan and Estepona, Est-Tet provides a vital link between the telecommunications networks of Morocco and Spain, facilitating international connectivity in the region.

Ownership and History

Est-Tet is jointly owned by Maroc Telecom and Telxius. Maroc Telecom is Morocco's leading telecommunications operator, with a significant presence across the country as well as in several sub-Saharan African markets. Telxius, a subsidiary of Telefónica, specializes in telecommunications infrastructure, including undersea cables and tower assets, with operations spanning multiple continents.

The cable was commissioned and became ready for service in 1994, making it one of the earliest submarine cables to connect Morocco and Spain directly. At the time of its deployment, it represented a significant technological advancement, providing a dedicated undersea pathway between the two nations. Over the years, the cable has continued to serve as a reliable link, even as newer and longer systems have been added to the corridor.

Est-Tet's longevity is notable: it has been operational for nearly three decades, a testament to its robust design and maintenance. Its historical significance lies in its role as a pioneer in the Morocco-Spain submarine cable corridor, paving the way for subsequent systems that have expanded connectivity between the two regions.

What Our Measurements Show

Our monitoring of the Est-Tet cable indicates that it continues to perform reliably, despite its age. The cable's relatively short length of 113 kilometres minimizes latency, ensuring efficient data transmission between Tétouan and Estepona. This direct connection remains a valuable asset for cross-border communication, particularly for applications requiring low latency.

Probes along the cable's route confirm its stable operation across the Strait of Gibraltar. The cable benefits from the relatively shallow depth of the strait, which simplifies installation and maintenance compared to deeper oceanic systems. However, the high level of maritime activity in the region necessitates rigorous monitoring to prevent potential disruptions caused by ship anchors or fishing activities.

While newer and larger systems have been deployed in the Morocco-Spain corridor, Est-Tet continues to hold strategic importance. Its direct route across the strait provides a dedicated pathway for telecommunications traffic, complementing the capacity offered by more extensive regional networks. The cable's enduring reliability underscores its role as a cornerstone of connectivity between North Africa and Europe.
