Google announces the world's longest single-powered submarine cable 'Firmina'



Google has announced the connecting from the US east coast to Las Toninasu of Argentina the world's longest submarine cable 'Firmina (Firumina)'. Firmina is laid from Las Toninas to Brazil's Praia Grande and Uruguay's Punta del Este, providing a comfortable access to Google services on the South American continent.

Regarding the reason for installing Firmina, Google said, 'As people and businesses have become dependent on digital services in many aspects of their lives, we plan to use Firmina to improve access to Google services by South American users.' I will. Firmina houses a pair of 12 fibers in a single cable, which seems to help transmit traffic quickly and safely between the Americas. This gives users fast, low-latency access to Google services such as Google Search, Gmail, and YouTube.

The laying route of Firmina is as follows.



Firmina is a submarine cable with a single-ended power supply capacity that can operate with a single power supply on the other side even if the power supply on one side is temporarily unavailable. This power feature is important for increasing 'reliability,' which is an important priority for Google's network.

In a submarine cable, data is transmitted as an optical signal through the optical fiber in the cable, and this optical signal is amplified every 100 km by the high voltage current supplied from the landing point of the submarine cable. For relatively short submarine cables, it is possible to operate with a single power source, but for long submarine cables that span intercontinents, multiple power sources must be used to amplify the optical signal. However, Firmina has succeeded in achieving a single-ended power supply capacity while connecting the Americas. In addition, by supplying a voltage 20% higher than the conventional system, it is said that it has realized a single-ended power supply capacity.

Google CEO Sundar Pichai also said in his Twitter account, 'Today we are announcing'Firmina'. Firmina is the world's largest submarine cable that can be operated from a single power source at one end if needed. It's the longest submarine cable. Farmina will be laid from the east coast of the United States to Argentina to improve access to Google services in South America, 'said Google, announcing the installation of a new submarine cable.



Firmina is named after Maria Filmina dos Wraith, who worked to abolish slavery in Brazil.
