How Undersea Cables Keep the Internet Running

Every second, billions of messages, videos, emails, and financial transactions travel across the internet. But have you ever wondered how all that information crosses the oceans? The answer lies deep beneath the waves. Across the ocean floor, an enormous network of fiber-optic cables connects continents and carries international internet traffic around the world. In this documentary, you'll discover how undersea internet cables work, how data travels through optical fibers using pulses of light, why repeaters are needed across long distances, how massive cable-laying ships install these cables, and what happens when one breaks. We'll also explore how damaged cables are repaired at sea and follow the journey of an internet request from your home, across an ocean, to a server thousands of kilometers away. The internet may feel wireless, but behind the digital world lies an extraordinary physical infrastructure hidden at the bottom of the ocean.
