Argentina Joins the Butterfly-Shaped Optical Cable 8 Cores

Argentina is now connected to the high-capacity Firmina subsea cable, featuring 12 fiber pairs and butterfly-shaped optical cable technology, enhancing international connectivity and digital infrastructure.

Overview of the Firmina Subsea Cable

Argentina's Las Toninas landing site now hosts the Firmina submarine cable, a project led by Google with participation from Telxius and other partners. The cable runs from the East Coast of the United States to Argentina, with additional landings in Brazil (Praia Grande) and Uruguay (Punta del Este), spanning approximately 13,500–14,000 km . This deployment significantly increases Argentina's international bandwidth and redundancy, complementing existing systems like the Tannat cable .

Technical Features

• Fiber Structure: Firmina uses 12 fiber pairs, which are often implemented in a butterfly-shaped optical cable design to optimize space, reduce signal distortion, and improve transmission efficiency .
• Transmission Capacity: The butterfly-shaped design allows low optical loss, enabling long-distance signal transmission with minimal degradation. Single-mode fibers are typically used, supporting high-speed, low-latency data transfer over thousands of kilometers .
• Power Feeding: Firmina is the longest cable capable of single-end power feeding, supplying a higher voltage to maintain signal amplification across the entire route, enhancing reliability .
• Redundancy and Resilience: With Telxius hosting the cable in its Santos digital hub, the network benefits from multiple redundant routes between the US, Brazil, and Argentina, ensuring robust connectivity and low-latency performance .

Strategic Impact for Argentina

• Enhanced Connectivity: The cable doubles Argentina's accessible submarine cable capacity, improving access to cloud services, streaming platforms, and international data exchange .
• Economic and Digital Growth: By connecting to a high-capacity, resilient network, Argentina can support digital economy expansion, attract data center investments, and improve internet reliability for businesses and consumers .
• Integration with Regional Networks: Firmina complements other Google-operated cables in South America, such as Curie (US-Chile) and Monet (US-Brazil), creating a continent-wide high-speed network .

Conclusion

Argentina's connection to the butterfly-shaped, 8-core (or 12 fiber-pair) Firmina subsea cable represents a major upgrade in international telecommunications infrastructure. The combination of high-capacity fibers, low-loss transmission, and single-end power feeding ensures reliable, fast, and scalable connectivity, positioning Argentina as a key node in the Americas' digital network .
