Light Speed: The Story of Fiber Optic Communication
from David's NotebookLM Audio Collection · host David Weissman
Explore the remarkable story of fiber optic cables, the glass threads that carry modern life at the speed of light. This Deep Dive traces the history of optical communication from early experiments with guiding light to lasers, Charles Kao’s breakthrough insights, Corning’s low-loss fiber, and the global networks that now power streaming, telemedicine, cloud computing, AI, and everyday internet use. Along the way, we unpack the elegant physics of total internal reflection, explain why fiber is faster and more reliable than copper, and reveal how invisible pulses of light became the backbone of our connected world.
