Who laid the fiber optic cable

Fiber optic cable was pioneered by Narinder Singh Kapany, with major advancements by Charles Kao, George Hockham, and Corning Glass Works.

Early Invention and Pioneering Work

The concept of transmitting light through glass fibers was first practically demonstrated by Dr. Narinder Singh Kapany in the 1950s, who is widely recognized as the “Father of Fiber Optics.” Kapany successfully transmitted images through bundles of glass fibers, laying the foundation for modern optical communication and coining the term “fiber optics” . He also co-founded Optics Technology, Inc. in 1960, one of the first companies to manufacture fiber optic systems for medical, industrial, and defense applications .

Breakthroughs in Long-Distance Communication

In the 1960s and 1970s, Charles Kao and George Hockham identified that signal loss in glass fibers was primarily due to impurities. They proposed that highly purified glass could transmit light over long distances, a discovery that became the cornerstone of modern fiber-optic communication and earned Kao the Nobel Prize in Physics in 2009 .

Commercial Development

The first low-loss optical fibers capable of practical long-distance communication were developed by Corning Glass Works in 1970, using a vapor deposition method to produce high-purity glass fibers . This innovation enabled the first commercial fiber-optic links, such as the 1977 installation by General Telephone and Electronics (GTE), demonstrating the technology's viability for telecommunications .

Summary

While Kapany invented the first functional fiber optic cable, Kao and Hockham's theoretical work and Corning's manufacturing breakthroughs were critical in making fiber optics practical for global communication networks. Together, these contributions transformed fiber optics from a laboratory experiment into the backbone of modern high-speed internet, medical imaging, and secure communication systems .
