Google is building another sub-sea cable to improve their capabilities with Alcatel.…o-south-africa

Below, a map of the current situation, not bad, isn’t it?

The key aspect of all this is the space-division multiplexing (SDM) technology. To summarize how powerful it is:

In 1858, Queen Victoria sent the first transatlantic telegram to U.S. President James Buchanan, sending a message in Morse Code at a rate of one-word per minute. In Q3 of 2020, when we turn on our private Dunant undersea cable that connects the U.S.A. and France, it will transmit 250 Terabits of data per second—enough to transmit the entire digitized Library of Congress three times every second.
