Fiber-Optic Communications

Fiber-optic communication sends information as pulses of light through thin, ultra-pure glass fibers, carrying enormous bandwidth over long distances with little loss. It is the backbone of the modern internet.

Attribution — A defined team or small group developed it together.

Charles Kao showed in 1966 that pure enough glass could carry light over long distances (Nobel Prize, 2009), but realizing it required Corning's team — Robert Maurer, Donald Keck, and Peter Schultz — who made the first low-loss fiber (1970), plus decades of laser and cable engineering.

What counts as the invention: The insight/target (Kao) is distinct from the materials breakthrough (Corning) and the systems engineering that followed.
