Optical Fiber Classification Notes by Waqqas
 
1 Attachment(s)
Optical Fiber Classification
  • Can be classified in a number of ways
  • On the basis of manufacturing
  • Single component/Multi component
  • Glass core glass clad
  • Doped silica core clad
  • All plastic fiber
  • On the basis of profile
  • Step index
  • Multi mode
  • Mono mode
  • Graded index
Multi Mode Step Index
Made up of glass or doped silica
Reasonably large core diameter and NA to facilitate efficient coupling of incoherent light
Performance characteristics vary widely depending upon material used in fabrication
Structure
Core diameter: 50 to 400 µm
Clad diameter: 125 to 500 µm
Buffer jacket diameter: 250 to 1000 µm
Numerical Aperture: 0.16 to 0.5
