Google’s Firmina submarine cable will connect the United States to Brazil, Argentina and Uruguay

Google is making a big effort to improve connectivity in South America with its new Firmina submarine cable. It will stretch from the east coast of the United States to Las Toninas, Argentina, with additional connections to Punda del Este, Uruguay and Praia Grande, Brazil. Notably, Google says it is the world’s longest submarine cable that can be fed from a single end, which should help stabilize its connection in the event of power supply issues. Firmina brands Google’s 16th investment in submarine cable, which also includes the Curie cable connecting the United States and Chile, and the Grace Hopper Cable which reaches the UK and Spain.


It’s easy to forget this when we mainly talk about wireless connectivity and satellites, but submarine cables remain the most crucial means of spreading network connectivity to the world. Google says the Firmina cable will have 12 fiber pairs, which should both speed up network traffic and reduce latency for Google services like Search and Gmail (of course). The cable bears the name Maria Firmina dos Reis, a Brazilian abolitionist and novelist who explored the lives of Afro-Brazilian slaves in her 1859 novel Úrsula.
