FIBER OPTIC CABLE

The journey began in 1854, when John Tyndall demonstrated that light could travel through a curved stream of water—an early hint at total internal reflection, the principle behind fiber optics.
In 1880, Alexander Graham Bell invented the Photophone, which transmitted sound using a beam of light. It was brilliant but impractical—cloudy weather could ruin the signal.

Fast forward to the 1950s–60s, when researchers began experimenting with glass fibers to guide light.
The real breakthrough came in 1970, when Robert Maurer, Donald Keck, and Peter Schultz at Corning Glass Works created the first low-loss optical fiber—capable of transmitting data over long distances without significant signal degradation.
Their invention could carry 65,000 times more data than copper wire, opening the door to high-speed communication.

In 1977, the first live telephone traffic was carried over fiber optic cables.
By the 1990s, fiber optics had become the backbone of the internet, telecom, and cable TV industries.
Today, fiber optic cables are thinner than a human hair and can transmit data at near light speed, powering everything from streaming services to cloud computing.

High bandwidth: Supports massive data loads—perfect for HD video, gaming, and enterprise networks.
Low signal loss: Ideal for long-distance communication without repeaters.
Immunity to interference: Unlike copper, fiber isn’t affected by electromagnetic noise.
Security: Much harder to tap than traditional cables.
