Google is building an undersea cable to link South America, including Brazil, to the United States. In total, the installation must connect the beach of Las Toninas, in Argentina, with the east coast of the USA. The route includes passages through Praia Grande, on the coast of São Paulo, and Punta del Este, in Uruguay. Once completed, the Firmina, as it was named, must be the submarine cable longest in the world.

Made from optical fiber, the cable must be able to work with only one power source at one end to ensure a stable connection. The purpose of the installation is to improve the access of people in South America to Google services.

“As people and businesses come to rely on digital services for many aspects of their lives, Firmina will improve access to Google services for users in South America,” said Bikash Koley, vice president of Global Networking for Google Cloud .

According to Google, in an undersea cable, data is carried by light streams that travel along the fiber. Generally, this type of connection relies on high-voltage power supplies installed at all the cable stops in the countries where the cable runs.

However, Firmina, despite its length, will be able to work with only one power source at its ends. This ensures that the connection will remain active even if there is a problem with other sources. “Achieving this highly resilient design, which represents a record-breaker, was possible by providing a 20% higher voltage for this cable than that used in previous systems,” completes the statement.

The name of Google's submarine cable is in honor of the Brazilian Maria Firmina dos Reis (1825 – 1917), the abolitionist writer responsible for the novel Úrsula. She is considered the first Brazilian novelist.
