The Invention of Optical Fiber

Fiber optic, also known as optical fiber, is a slender transparent material used for long-distance, high bandwidth information transmission. In 1966, Chinese scientist Gao Kun, known as the "father of optical fibers", pioneered the basic principles of the application of optical fibers in communication. In 1970, Corning Inc. successfully developed low loss optical fiber, achieving a major breakthrough in fiber optic communication technology. Fiber optic has quickly become the backbone of modern communication networks due to its fast transmission speed, large capacity, and strong anti-interference ability.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

When light travels from a dense medium to a sparse medium and the incident angle is greater than the critical angle, the refracted light disappears completely, leaving only the reflected light. This phenomenon is called total reflection. Fiber optics use the principle of total reflection of light to transmit light from one end to the other. A single optical fiber transmits a single light point, and the fiber array formed by fiber bundles can also transmit images, resulting in patterns on disks in the display area. Fiber optic communication is the use of light as a carrier, utilizing the principle of total reflection of light to achieve near lossless long-distance transmission of information.
