  1. 1. C B KORE POLYTECHNIC CHIKODI Topic : FIBER OPTIC COMMUNICATION BY: SHARVANI MUSANDI VI sem EC VANDANA DESAI VI sem EC
  2. 2. BRIEF FLOW OF THE PRESENTATION 1. Introduction 2. Construction of optical fiber 3. Working principle 4. Fiber optic configuration 5. Working of optical fiber 6. Advantages of Optical fiber 7. Application of fiber optics 8. Reference
  3. 3. OPTICAL FIBERCAUSES FOR THE CREATION OF THE OPTICAL FIBER----- Man’s HUNGER Lastly optical fiber’s were invented to satisfy the Man’s hunger for communication
  4. 4. CONSTRUCTION OF OPTICAL FIBER Core Cladding Buffer coating
  5. 5. TOTAL INTERNAL REFLECTION When light travelling in an opticallydense medium hits a boundary at an anglelarger than the "critical angle" for themedia, the light will be completelyreflected. This is called total internalreflection. Fiber optic cables use total internalreflection inside the optical fiber.
  6. 6. TOTAL INTERNAL REFLECTION
  7. 7. FIBRE OPTIC CONFIGURATIONSINGLE MODE AND MULTI MODE OPTICAL FIBER
  8. 8. STEP INDEX FIBER The refractive index of core is constant The refractive index of cladding is constant The refractive index of cladding is slightly lower than that of core
  9. 9. GRADED INDEX FIBER Refractive index of core decreases smoothly from the centre to the outer edge Refractive index of cladding is constant
  10. 10. WORKING OF OPTICAL FIBER Light Transmission
  11. 11. ADVANTAGES Much higher bandwidth Thousands of channels can be multiplexed together over one strand of fiber Less expensive Higher carrying capacity Less signal degradation Light signals Digital signals Safety Non-flammable Lightweight Flexible
  12. 12. ADVANTAGES The optical fiber hasfollowing advantages overtwisted -pair and coaxialcable.• Resistance to noise• Huge bandwidth• Higher signal carryingcapacity
  13. 13. APPLICATIONS• Medical• Military• Electronics IBM microprocessors
