CAVI SOTTOMARINI - la fibra ottica del mondo passa in fondo agli oceani, altro che satelliti - Ep-1

Ninety-seven percent of global internet traffic runs on 1.3 million kilometers of undersea cables laid on the ocean floor; forget about clouds and satellites. In this new video series, "Submarine Cables," we tell the true story of the internet and explain how data and information travel along fiber optic cables at the bottom of the ocean. In this first episode, we'll focus on the history of the first undersea cable dating back to the 1800s and the different types of cables that exist. 00:00 Intro 01:08 How many kilometers of undersea cables are laid on the ocean floor? 01:34 The first undersea telecommunications cable 02:45 What speeds do undersea cables reach? 03:03 Types of undersea cables and fiber optics 04:06 What is a submarine data transmission cable made of? 04:59 How wide is it? 05:23 Electricity cables 06:04 The length of submarine cables 07:32 How do you decide where to lay cables?
