You’re correct!

It’s actually all quite impressive, check out the below interactive under sea cable map [here](https://www.submarinecablemap.com/).

Edit: Interestingly, most cables are owned by many telecommunications companies at each end, however, there are some owned by single parties e.g Google!

Edit 2: There are stats on each cable including date laid, ownership, length etc

There is a superhighway of fiber optic cables laid along the bottom of the oceans. In some instances, a satellite connection is used for remote locations.
