Reseña del libro "The Undersea Cable: The Machine That Wires the World (en Inglés)"
Why does a single dragged ship's anchor in the Red Sea knock out internet traffic for three countries - and why does almost no one notice when it happens?Ninety-nine percent of intercontinental internet traffic - email, video calls, bank transfers, the cloud itself - crosses the ocean floor through glass fibers no wider than a strand of hair. This book opens that machine: the physics that lets light survive six thousand kilometers of glass, the ships that lay it at bicycle speed, and the surprisingly small number of people who keep the whole thing running.Inside, you'll find: How light survives an ocean. A signal loses half its strength every twenty kilometers, restored by a titanium cylinder every seventy kilometers - sealed once, expected to run for twenty-five years, never opened again.Why "thinner than a hair" is true and also isn't. The part that carries the light is an eighth the width of a human hair. The glass strand around it is one to two hairs wide. Both numbers matter.One hundred and seventy years of failure before it worked. From a telegraph cable that died after three weeks in 1858 to a fiber pair carrying 1.7 million times more data than the first transatlantic cable, within one working career.Who actually owns the ocean floor. Roughly sixty aging ships, three factories, and four American companies renting three-quarters of the world's international bandwidth - none of whom own a single cable ship.What happens when it breaks. It happens 150 to 200 times a year, almost always by accident, and the record for the strangest repair belongs to a volcano in Tonga.No engineering background is required. Every comparison is computed and shown, not asserted, and every disputed number names who is disputing it.The ocean did not get smaller. Someone built a machine that made the distance not matter.
