Google's 'Firmina' Subsea Cable Will Connect North And South America

According to 9to5Google, Google has a new subsea cable that it is planning. Google’s ‘Firmina’ subsea cable will be the “longest cable in the world capable of running entirely from a single power source.” What does that mean?

Well, it means that in the event that other power sources go out, ‘Firmina’ will keep running. If other power sources go out ‘Firmina’ will supply the cable with 20% higher voltage compared to previous systems. This backup will be important to keep things running smoothly.

Google goes on to explain this in more detail:


With submarine cables, data travels as pulses of light inside the cable’s optical fibers. That light signal is amplified every 100 km with a high-voltage electrical current supplied at landing stations in each country. While shorter cable systems can enjoy the higher availability of power feeding from a single end, recent longer cables with large fiber pair count have made this harder and harder. “

Google’s ‘Firmina’ subsea cable will connect North and South America

Now the new subsea cable will connect North America to South America. It will start on the East Coast of the United States and run to Los Toninas, Argentina. In addition, there will be two more landings in Praia Grande, Brazil, and Punta del Este, Uruguay.

Of course, this isn’t Google’s first foray into subsea cables. In fact, the search giant has been building some over the past few years. The other cables are Curie which runs from the US to Chile and Panama. There is Dunant which runs from the US to France. There’s also Equiano which runs from Portugal to South America. Lastly, there’s Grace Hopper which runs from the US to the UK and Spain.


Google names their subsea cables after notable world figures. Of course, Google is keeping the tradition with the new ‘Firmina’ subsea cable.

We sought to honor a luminary who worked to advance human understanding and social justice. The cable is named after Maria Firmina dos Reis (1825 – 1917), a Brazilian abolitionist and author whose 1859 novel, Úrsula, depicted life for Afro-Brazilians under slavery. A mixed-race woman and intellectual, Firmina is considered Brazil’s first novelist. With this cable, we’re thrilled to draw attention to her pioneering work and spirit. You can learn more about Firmina in this Google Doodle.”

Google does a lot when it comes to advancing technology worldwide. This new subsea cable will surely be a worthy addition to the company’s portfolio.
