The owners of the famous channel on YouTube Whats Inside in search of a piece of these cables to see if they may cut a part of them to know more closely and how they are from the inside. Those who helped these people were two YouTube users from Nat and Friends. Previously, they had visited a dock where a ship was being loaded to install a new cable under the sea linking the United States to Brazil. They could come with a portion of the cable.
Then they showed how these cables are made, which are mainly made to protect the fiber optic wires from the inside. At the least thin part, we have at least eight different layers. The outer part is made of polyethylene, the second is the fiber of the same material. Then there are two layers of twisted steel cables, responsible for all the structural strength of these marine cables.
Between steel cables and internal protection of plastics there can be another aluminum shield, and inside our plastic copper wire, which works to transfer electricity to the two parts installed in every few miles. Finally, we have another plastic protection, then several plastic tubes with pairs of fiber optic cables coated with different colors.
The cable made by YouTube users is part of a cable installed by Algar Telecom, Google and other companies between Brazil and the United States. The idea is to link Santos (SP) and Fortaleza (CE) to Boca Raton, Florida in North America.
