How Fiber Optic Cable is Made | The Hair-Thin Thread Stronger Than Steel

Описание: How do you turn common sand into a thread so pure it can carry a signal at the speed of light for thousands of miles? The answer lies in a manufacturing process cleaner than a surgical room and more precise than a Swiss watch.

In this video, we reveal the incredible journey of creating fiber optic cable. Witness a massive glass preform being heated to 4,700°F and drawn into a flawless fiber thinner than a human hair. We'll show you the high-speed coating process that armors this fragile thread, and how it's bundled with Kevlar to build the invisible highways that connect our digital world. This is the story of light itself being tamed.
