Google is expanding its network of undersea internet cables with a new fiber optic line running between the US and South America.
The Firmina cable, named after Brazilian abolitionist Maria Firmina dos Reis, will run from the east coast of the US to Argentina, with two branches docking in Brazil and Uruguay.
Once finished, Firmina will be the longest subsea cable capable of running from a single power source, minimizing the likelihood of a power-related blackout.

“With submarine cables, data travels as pulses of light inside the cable’s optical fibers. That light is amplified every 100km with a high-voltage electrical current supplied at landing stations in each country,” explained Google in a blog post (opens in new tab).
“While shorter cable systems can enjoy the higher availability of power feeding from a single end, longer cables with large fiber-pair counts make this harder to do.”
Firmina will address this issue by hitting the cable with 20% higher voltage than traditional systems.

With twelve fiber pairs, Firmina will also be among the highest capacity subsea cables in the world. For perspective, a single fiber pair is capable of carrying millions of high-definition videos simultaneously.
Google says the new cable will help give users in South America fast and low-latency access to its various products, such as Search, Gmail, Youtube and Google Cloud services.
The hope is also to provide an all-important boost to resiliency, during a period in which connectivity is more important than ever, with opportunity for physical travel limited by the pandemic.
With Firmina, Google now owns at least a portion of sixteen different subsea cables, many of which are co-owned with fellow tech giants Amazon, Microsoft and Facebook.
The new cable also extends the company’s existing network in the region, which includes Tannat, Monet and Junior cables that serve various areas of South America.
