BELLA in a Nutshell

BELLA (Building the Europe Link with Latin America) provides for the long-term interconnectivity needs of European and Latin American research and education communities.

BELLA will achieve this through the procurement of a long-term Indefeasible Right of Use (IRU) for spectrum on a submarine cable between the two regions, minimising latency. BELLA is also developing and deploying a 100Gbps-capable research and education network across Latin America.

BELLA is being implemented by a Consortium of Regional Research and Education Networks GÉANT (Europe) and RedCLARA (Latin America) and the National Research and Education Networks (NREN) of Brazil, Chile, Colombia, Ecuador, France, Germany, Italy, Portugal and Spain.

Funding for BELLA is provided by the European Union through three European Commission (EC) Directorates (DG-CONNECT, DG-DEVCO and DG-GROWTH) and by the Latin American NREN community.

The BELLA (Building the Europe Link with Latin America) Programme objectives are to strengthen connectivity between Latin America and Europe ensuring high capacity, cost effective capacity, shorter routes to stimulate data-sharing across the Atlantic.

This will be done by securing the guaranteed long-term use of spectrum on a direct telecommunications submarine cable between Latin America and Europe and by implementing sufficient capacity between the GÉANT and RedCLARA networks to match the needs of the research and education communities in the two regions.

Obtaining spectrum on a direct cable between the two regions means latency will be reduced, which will benefit users for whom data transmission speed is important. Furthermore, data security will be enhanced as traffic will be routed directly between the two regions, and not via other third-party countries.

The BELLA partners will also establish a 100Gbps-capable RedCLARA backbone in South America. By interconnecting the transatlantic BELLA spectrum with the RedCLARA backbone and the GÉANT network in Europe the BELLA programme will ensure seamless end-to-end connectivity in the long-term for use by the research and education communities of the two regions.

The project will also contribute to strengthening the close working relationships between the European and Latin American research and education networking communities, significantly improving the long-term collaboration between the two regions.

The BELLA Programme is composed of two complementary and interdependent actions: BELLA-S and BELLA-T.

  • BELLA-S: By securing rights to spectrum on a direct submarine cable between the two regions, BELLA-S will provide for the data-sharing needs of the European and Latin American research and education communities for the next quarter of a century.
  • BELLA-T: By completing the terrestrial optical fibre network infrastructure of RedCLARA (a complementarily action to the previous one), a significant improvement of the Latin American Network will be achieved. This enhancement will ensure that the enormous step forward of the transcontinental capacity will be evenly distributed across the region, and through the synergy with the NRENs will enhance capillarity and equal access to the intercontinental services by all Latin American users.


  •     To obtain Indefeasible Right of Use (IRU) of 40 optical channels on a direct submarine cable between Europe and Brazil.
  •     To deploy two upgradeable 100Gbps links for:
    • GÉANT-RedCLARA interconnection;
    • Copernicus traffic.
  •     To complete the RedCLARA dark fibre network and deploy a 100Gbps upgradeable network from Brazil to Colombia.
  •     To form the human capital required to deploy, maintain and operate optical networks.
