Classification of optical fiber.pptx

  1. Glass optical fibers have higher information transmission capacity with lower loss. They are ideal in corrosive environments or extreme temperatures. Plastic optical fibers have great flexibility and are lighter in weight. They can withstand vibration and unstable environments.
  2. Plastic optical fibers have great flexibility and are lighter in weight. They can withstand vibration and unstable environments. Optical fibers are most commonly made of 3 materials: large core plastic fiber, small core plastic fiber, and glass fiber.
  3. Single Mode (SM) and Multimode (MM) are the names given to two competing designs of optical fiber based on how many paths of light are transmitted along the fiber core – single mode, meaning “one path”.
  4. A multimode fiber is a fiber supporting propagation of multiple modes. The cable has a core diameter of 50-100 microns. It causes more distortion and gives less bandwidth than single-mode (monomode) fiber.
  5. Step index optical fiber describes any optical fiber which is designed to transmit signals in the step–index pattern, that is, on the basis of total internal reflection whereby the light ray propagates in a zig-zag manner.
  6. A graded-index or gradient-index fiber is an optical fiber whose core has a refractive index that decreases with increasing radial distance from the optical axis of the fiber.
