This design includes answers to some of the most-asked cable questions in our queue, from how many kilometers of cable you can find under the sea to how much information is carried by a cable. Over the next three years, we could see more than 60 new cables constructed totaling over 290,000 km in length. Accounting for less than 10% of total usage prior to 2012, content providers‘ share of capacity surged to 66% in 2020. Unlike previous cable construction booms, content providers like Amazon, Google, Facebook, and Microsoft are taking a more active role in this recent surge.
