Xtera selected for Argentina-Brazil subsea cable system

Xtera has been chosen to supply the ARBR submarine fibre optic cable system, which was developed jointly by Seaborn Networks and Werthein Group, and will connect Argentina and Brazil.

This will be Argentina’s first independent submarine cable system, providing the most direct route between Argentina and the United States using onward connectivity via the Seabras-1 submarine cable system between New York and Sao Paulo. The 2,700km open system, four-fibre pair, direct point of presence (PoP)-to-PoP subsea cable will have an initial design capacity of 48Tb/s. It will utilise Xtera's submarine repeaters with hybrid erbium-doped fibre amplifier and Raman design to enable a robust optimised transmission system.  

The ARBR system will be developed and owned by Seabras Group - a partnership between Seaborn Networks and equity investor Partners Group (see Partners Group funds Seabras-1 cable linking US and Brazil) and Werthein. The two companies announced their binding agreement to build the ARBR system in April last year (see Seaborn and Werthein to build submarine cable connecting Argentina to Brazil).
