DUBLIN, IRELAND – September 16, 2026 – In a move that signals a paradigm shift for South American digital infrastructure, EllaLink, the operator of the high-capacity fiber-optic submarine cable connecting Latin America to Europe, has announced the successful placement of two critical branching units on the seabed. These subsea nodes, positioned at depths of 3,920 and 3,690 meters, represent the foundational architecture for connecting the Brazilian states of Pará and Maranhão directly into the global subsea backbone.
This milestone, executed during the Lum@link marine campaign, is more than a technical achievement; it is a geopolitical and economic leap forward. By embedding these branching units into the existing deep-water network, EllaLink has effectively "future-proofed" the region, allowing for the seamless integration of landing stations in Salinópolis and São Luís without the need for disruptive future interventions.
The Strategic Anatomy of the Project
A branching unit is, in essence, a sophisticated underwater junction box. It allows operators to "tap" into an existing main trunk line and divert a portion of the data traffic to a new destination. By installing these units now, EllaLink ensures that when the Brazilian branches are finalized, they can be "switched on" with minimal friction.
The Lum@link system—a 2,100 km extension linking Cayenne, French Guiana, to the main EllaLink trunk off the coast of Fortaleza—serves as the conduit for this connectivity. For the states of Pará and Maranhão, this represents an exit from the constraints of terrestrial backhaul. Historically, these states have relied on long-distance, overland fiber networks to reach international gateways, a model plagued by latency and vulnerability to physical disruption. The new subsea branches provide a direct, high-capacity, and resilient path to Fortaleza, Cayenne, and eventually, the digital hubs of Europe.
Chronology: From Concept to Seabed Deployment
The road to this week’s milestone has been a multi-year effort involving international diplomacy, complex engineering, and cross-border investment.
- Mid-2026 (July): The cable ship CS Île d’Yeu departs from the Alcatel Submarine Networks (ASN) facility in Calais, France. This signaled the formal commencement of the Lum@link marine installation campaign.
- August 2026: The vessel reaches the operational theater in the Atlantic, beginning the intricate process of laying fiber and installing the branching units.
- September 16, 2026: EllaLink confirms that the branching units are successfully positioned on the seabed, marking the completion of the foundational marine phase.
- Late 2026 (Projected): Lum@link is scheduled to enter full service, providing the essential bridge between French Guiana and the main EllaLink trunk.
- Post-2026: Subject to the finalization of local funding and engineering surveys, the connection of the land-based stations at Salinópolis and São Luís will commence, completing the "Mais Conectado" vision.
Empowering the Amazon: Data and Implications
The impact of this project on the Brazilian North and Northeast regions cannot be overstated. With an initial combined capacity of 17 Tbps, the project provides a massive injection of bandwidth, but the implications extend far beyond raw speed.
A Catalyst for Digital Equality
For the states involved, this is a matter of digital sovereignty. The capacity carried on each branch is owned and commercialized by the states themselves—specifically through ATI (Agência Estadual de Tecnologia da Informação do Maranhão) and PRODEPA (Empresa de Tecnologia da Informação e Comunicação do Estado do Pará). This state-controlled infrastructure model allows local governments to dictate the terms of connectivity, fostering:
- Healthcare: Telemedicine reaches isolated communities, providing rural populations with access to specialized consultations in urban centers.
- Education: High-speed internet enables digital classrooms, closing the geographic gap between Amazonian students and global knowledge repositories.
- E-Government: The strengthening of public services through a stable, resilient network will modernize administrative processes, from tax filing to civil registration.
Environmental Stewardship through SMART Sensors
A unique feature of this deployment is the integration of SMART (Science Monitoring And Reliable Telecommunications) sensors. These subsea instruments will collect real-time environmental and seismic data. By utilizing the cable as an ocean-observing network, the project contributes to global climate science, providing critical insights into the Atlantic environment and tectonic activity—a testament to the EU’s commitment to scientific advancement alongside digital growth.
The "Mais Conectado" Framework: A Team Europe Initiative
The project is a flagship component of the Mais Conectado initiative, an ambitious program designed to bring the Amazon Basin into the global digital economy. This project is a pillar of the EU Global Gateway strategy and the EU-LAC Digital Alliance, demonstrating a collaborative approach between European institutions and Latin American governments.
Funding for this massive undertaking is a tapestry of international support:
- Inter-American Development Bank (IDB) Group: Co-financing the infrastructure.
- Agence Française de Développement (AFD) Group: Providing technical and financial backing.
- European Union: Grant support through the Connecting Europe Facility (CEF) Digital programme, managed by the European Health and Digital Executive Agency (HaDEA).
This multilateral funding model ensures that the project remains economically viable while fulfilling public-interest objectives, such as lowering the cost of data and improving service penetration in underserved markets.
Official Perspectives: Leadership and Vision
The significance of the project is reflected in the statements from both the political and corporate leadership involved.
Carlos Brandão, Governor of the State of Maranhão, emphasized the long-term vision of the investment:
"Maranhão is preparing today to take a leading role in the digital economy of the future. We are investing in high-speed connectivity, fiber optic infrastructure, cybersecurity, data centers, and digital inclusion. This is a project that modernizes the state, strengthens our economy, and creates the conditions to attract investment. We want a Maranhão that is more connected, more competitive, and, above all, one where technology helps reduce inequality."
Philippe Dumont, CEO of the EllaLink Group, highlighted the technical foresight required for such a project:
"Laying these two branching units is one of those milestones that is invisible from the shore but decisive for everything that follows. They are the physical foundation of the future connections… Since its inception, the EllaLink system has been designed to welcome new markets step by step, and this is what that design was for."
Future Outlook: A Scalable Network
The Lum@link system is designed for longevity. By finalizing the Cable Route Study (CRS) and completing preliminary environmental assessments, EllaLink has cleared the bureaucratic and engineering hurdles that often stall subsea projects.
As the world increasingly relies on cloud computing, AI-driven public services, and globalized e-commerce, the physical layer of the internet—the subsea cable—becomes the most valuable asset a region can possess. For Pará and Maranhão, the seabed now holds the key to their digital future. With the branching units in place, the path is clear: the Amazon is no longer a peripheral node in the global network, but a central player in the next generation of international connectivity.
As 2026 draws to a close, all eyes will be on the activation of the Lum@link system, a definitive step toward a more connected, resilient, and inclusive digital landscape for South America.
