Undersea fiber optics cables: the backbone of the internet

Since fiber optics was invented in the 60s the world changed incredibly. We send lots of data via copper wires, like 100+ MB/s, but sending data via fiber optics can reach up to 1 TB/s which is a huge improvement.

In order to connect all the countries within the internet we use undersea cables from one continent to another one. The first such cable made specifically for the internet and which used fiber optics was TAT8, in service between 1988 and 2002.

Before that, we have been using undersea cables for the telegraph since the 1850s. You gotta love tech 😀
