EllaLink is a submarine cable connecting Brazil and Europe, linking the major hubs of Sao Paulo and Fortaleza with Lisbon and Madrid. The main section of the EllaLink cable traveling from Sines to Fortaleza is approximately 5900 km.

The EllaLink cable system delivers 100Tbps of capacity over 4 fibre pairs, up to 25Tbps per fibre pair capacity direct from Europe to Latin America.

The EllaLink cable system is supplied by ASN, with financial supports including but not limited to 

• a €25 million ($27.2m) financial support by the European Commission as part of its Building Europe Link to Latin America (BELLA) initiative.
• a €9.57 million grant by the EU Commission for development of submarine cable connecting Mauritania to Portugal and Europe, as part of the CEF (Connecting Europe Facility) programme
• a €13.69 million grant by the EU Commission for building the future Canary Islands submarine cable connection, as part of the CEF (Connecting Europe Facility) programme
• a €29.9 million grant under the CEF-Digital programme, to build the the Lum@link cable system, an extension of EllaLink cable to Cayenne, French Guiana.
• a €9.6 million grant under the CEF-Digital programme, to connect Mauritania to the Ellalink System main cable, providing connectivity between the Sahel region and Europe. The project costs a total of €29.5 million.

EllaLink was a partnership between Spanish submarine cable operator IslaLink and Brazilian state-owned telecoms provider Telebras. By the end of 2019, Telebras had withdrawn from the EllaLink cable project.

EllaLink collaborates with Telxius to land the cable at Telxius' Fortaleza Cable Landing Station. 

Ellalink creates a new landing site and an innovation & data center hub in Sines – Sines Tech.

The EllaLink cable system offers less than 60ms round trip delay (RTD) to cross the Atlantic connecting Portugal to Brazil, and less than 120ms RTD between Marseille and São Paulo.

The EllaLink cable system has been ready for service as of June 1, 2021.

The EllaLink Cape Verde Branch went live on June 6, 2022, with capacity up to 30Tbps. The project is budgeted at US $ 30 million (€ 24.9 million), with a financing support (loan) from the European Investment Bank (EIB), in the amount of US $ 25 million, with the approval of the Government of Cape Verde. 

In January 2024，EllaLink and SPLANG, part of Collectivité Territoriale de Guyane (CTG) and the associated municipalities of French Guiana, signed a contract which includes the construction of a new 2,100km cable extension to the existing EllaLink cable. This new submarine branch will land in Cayenne, French Guiana, and include 2 fibre pairs. The project is expected to cost €61.2 million, co-funded by the European Union with a €29.9 million grant under the Connecting Europe Facility (CEF) program, underscoring its significance and alignment with European Commission Digital Gateway priorities for robust and secure infrastructure.
