What are Fiber Optics

 

Fiber optics are optical cables that are in the form of long strands looking like a hair, they are made  of optically pure glass and are mainly used to carry digital information and now play a major role in the field of telecommunication in carrying information over long distances, even plastic can also be used as a substitute. They are also used for imaging in medical field in medical imaging and for inspection in mechanical fields. Fiber optics works based on a famous scientific principle known as total internal reflection of a wave.

Fiber optics is now gaining popularity because they are not only cheap and show less signal degradation. The things that one should keep in mind while buying them are length, width, brands, cost, damage and bandwidth. Fiber optics is a breakthrough achievement in the field of digital communication.

People can learn about fiber optics from here and can get to know on latest models of fiber optics that are available and also on the applications of different kinds of fiber optics.

When it comes to structure of fiber optics, there are three main parts namely the core, cladding and buffer coating. The thin glass centre of the fiber where the light travels is called core. Cladding is the outer optical material surrounding the core that reflects the light back into the core. Buffer coating refers to the plastic coating that protects the fiber from damage and moisture. Hundreds of these optical fibers are kept in a bundle and the bundle is protected by an outer covering know as jacket.

There are two types of optical fibers single mode and multiple modes. Single mode optical fibers have small core where as large core is present in multimode optical fiber. The optical fiber made from plastic have large cores. The small core helps in transmitting infrared laser light whereas the latter helps in transmitting infrared light from the led source.
