Fiber optics final

  1. 1. FIBRE OPTICS Tsang Siu Chung (11019700) Wong Ho Tsun(11008830) Yeung Sai Wing(11008768) Monday, 28 November 2011
  2. 2. PRESENTATION OUTLINE <ul><li>Objectives of this project </li></ul><ul><li>Principles of fibre optics </li></ul><ul><li>Applications of using fibre optics </li></ul><ul><li>Analysis on online survey results </li></ul><ul><li>Brief summary </li></ul>
  3. 3. OBJECTIVES <ul><li>How fibre optics can be used in our daily lives? </li></ul><ul><li>Why fibre optics? </li></ul><ul><li>How convenient are fibre optics? </li></ul><ul><li>How fibre optics changing our life and benefit us? </li></ul>
  4. 4. PRINCIPLES OF HOW IT WORKS
  5. 5. COMPONENT OF FIBER OPTICS <ul><li>Core - Thin glass center of the fiber where the light travels </li></ul><ul><li>Cladding - Outer optical material surrounding the core that reflects the light back into the core </li></ul><ul><li>Buffer coating - Plastic coating that protects the fiber from damage and moisture </li></ul>
  6. 6. DIFFERENT TYPES OF FIBER OPTICS <ul><li>Single-mode fibers have small cores and transmit infrared laser light (wavelength = 1,300 to 1,550 nm). </li></ul><ul><li>Multi-mode fibers have larger cores and transmit infrared light (wavelength = 850 to 1,300 nm) from LEDs. </li></ul>
  7. 7. THEORY OF FIBER OPTICS <ul><li>Total internal reflection : If the reflection index is lower on the other side of the boundary and the incident angle is greater than the critical angle, no light can pass through and all of the light is reflected. </li></ul>
  8. 8. WHAT WAYS CAN FIBER OPTICS USED IN? <ul><li>Communication </li></ul><ul><li>Medical </li></ul><ul><li>Other use </li></ul>
  9. 9. FIBER OPTICS USED IN COMMUNICATION <ul><li>CATV(cable television) : provide TV programs via radio frequency (RF) signals through optical fibers. </li></ul><ul><li>Data Transmission Fiber Optics : a sending and receiving of data from point to point via a network. </li></ul><ul><li>Internet system : Internet use the standard Internet protocol suite (TCP/IP) to serve billions of users worldwide. It’s mainly linked by optical networking technologies. </li></ul>
  10. 10. MEDICAL AND OTHER USE OF OPTICAL FIBER <ul><li>Fiberscope : examine small components in tightly packed equipment </li></ul><ul><li>Optical fibers sensors : measure strain, temperature, pressure and other quantities by modifying a fiber </li></ul><ul><li>Illumination : Light tubes or light pipes are used for transporting or distributing natural or artificial light. </li></ul>
  11. 11. HOW GOOD IT IS ? <ul><li>Cost - </li></ul><ul><li>1.Fiber optics glass cost less as compared to copper wires </li></ul><ul><li>Efficiency - </li></ul><ul><li>1. Speed of data transfer is faster. </li></ul><ul><li>2. Light signals degrade lesser than copper conductors . </li></ul><ul><li>3. Light signals require lesser power to be transmitted. </li></ul><ul><li>Convenience - </li></ul><ul><li>1. Less weight and more flexible than copper wires. </li></ul><ul><li>2. Easier to carry, bundle and set up. </li></ul><ul><li>3. Do not heat up and are non-flammable. </li></ul>
  12. 12. ANALYSIS OF THE ONLINE SURVEY RESULTS <ul><li>Conducted through Qualtrics </li></ul><ul><li>Over 80 respondents aged from 18 to 45-year-old </li></ul><ul><li>12 questions involved, ranged from personal habits to </li></ul><ul><li>business companies </li></ul>
  13. 13. DOES YOUR COMPANY(OR SCHOOL) USE FIBER OPTICS ? 64% of respondents vote yes Fibre optics are popular in the daily life
  14. 14. DO YOU USE FIBER OPTICS AT HOME ? <ul><li>64% of respondents vote yes </li></ul><ul><li>Fibre optics is a useful tool </li></ul><ul><li>Providing faster speed </li></ul>
  15. 15. DO YOU THINK FIBER OPTICS IS CONVENIENT ? <ul><li>A majority of people vote yes </li></ul><ul><li>Fibre optics is well-used </li></ul><ul><li>Fibre optics is more compact, less space is used </li></ul>
  16. 16. DO YOU KNOW FIBER OPTICS CAN BE USED IN MEDICAL SERVICES ? <ul><li>Many respondents vote no </li></ul><ul><li>Medical services with fibre optics are so new to people </li></ul><ul><li>Not a well-known use </li></ul>
  17. 17. HOW MUCH DO YOU SATISFY WITH THE PERFORMANCE OF FIBER OPTICS ? (1-LEAST, 5-MOST) <ul><li>People mostly are satisfied with the fibre optics </li></ul><ul><li>It is convenient and does not cost much </li></ul>
  18. 18. WHICH ONE DO YOU PREFER FOR INTERNET CONNECTION? - People love using fiber optics much more than copper wire - People are generally adapted to using fiber optics
  19. 19. DO YOU KNOW THE THEORY BEHIND FIBER OPTICS TECHNOLOGY ? <ul><li>Some people don’t know the basic principles of the operation of fiber optics </li></ul><ul><li>People just focus on how the tool benefits them basically </li></ul>
  20. 20. DO YOU THINK FIBER OPTICS IS A SIGNIFICANT IMPROVEMENT IN THE MODERN TECHNOLOGY HISTORY ? <ul><li>The discovery of fiber optics is brilliant </li></ul><ul><li>This innovation signifies the huge improvement in the modern technology history </li></ul>
  21. 21. ~THE END~ <ul><li>Thank you for watching </li></ul>
