  1. FIBER OPTICS
  2. DEFINITION DEFINITION: An optical fiber cable is a CABLE containing one or more optical fibers that are used to carry light. • It is made of glass or plastic and transmits signals in the form of light.
  3. PICTURE OF FIBRE OPTIC
  4. HOW OPTIC FIBRE CABLE WORKS? Typical Fiber Construction Cladding Core Buffer Coating CZOu Core - Thin glass center of the fiber where the light travels Cladding - Outer optical material surrounding the core that reflects the light back into the core Buffer coating • Plastic coating that protects the fiber from damage and moisture Hundreds or thousands of these optical fibers are arranged in bundles in optical cables. The bundles are protected by the cable's outer covering, called a jacket. Based on principle is total internal reflection. If any impurities is present ,then the light is absorbed by that .
  5. Principle of fibreoptics OTAL INTERNAL REFLECTION traveling in an optically dense hits a boundary at an angle larger than the "critical angle" for the media, the light wiil be completely reflected. This is called total internal reflection..Fiber optic cables Case total internal reflection inside the optical fiber. The light enters the optical fiber, and every time it strikes the edge of the fiber it experiences total internal reflection. This way the light travels down the length of the optical fiber.
