How Undersea Internet Cables Are Made and Tested

In this video, we take you inside a high-tech cable factory to see how undersea internet cables are made and tested through a complex manufacturing process. You will discover the complete production journey — from optical fiber preparation, copper conductor layering, insulation, steel wire armoring, waterproof protection, cable extrusion, giant cable spooling, electrical testing, pressure testing, water tank testing, and final undersea internet cables ready for ocean deployment. This factory tour shows how fiber optic technology, industrial cable machines, extrusion lines, armoring machines, testing systems, quality control, and precision engineering work together to build the cables that carry internet data across oceans. If you enjoy how it’s made videos, factory documentaries, fiber optics, undersea cables, modern manufacturing, industrial machines, production lines, and satisfying factory processes, watch until the end.
