  3. FIBER OPTICS

  4. What Is Fiber Optics ? • Transmitting communications signals over hair thin strands of glass or plastic. • Not a "new" technology • Used commercially for last 25 years.

  5. Fiber Optic Advantages • Fiber is the least expensive, most reliable method for high speed and long distance communications. • Fiber Optics cable have greater bandwidth than metal cables due to which they can carry more data.

  6. Fiber Has More Capacity This single fiber can carry more communications than the giant copper cable.

  7. Fiber Types

  8. Why Use Fiber Optics? • Economics • Speed • Distance • Weight/size • Freedom from interference • Electrical isolation • Security

  9. Fiber Optic Communications • Applications include • Telephones • Internet • LANs - local area networks • CATV - for video, voice and Internet connections • Utilities - management of power grid • Security - closed-circuit TV and intrusion sensors • Military – everywhere.

  10. Fiber Optic Applications • Fiber is already used in: • > 90% of all long distance telephony • > 50% of all local telephony • Most CATV networks • Most LAN (computer network) backbones • Many video surveillance links.

  11. Fiber Structure

  12. Fiber Technology

  13. Light Used In Fiber Optics • Fiber optic systems transmit using infrared light, invisible to the human eye, because it goes further in the optical fiber at those wavelengths.

  14. Fiber Optic Cable • Protects the fibers wherever they are installed. • May have 1 to over 1000 fibers.

  15. Fiber Optic Connectors • Terminates the fibers. • Connects to other fibers or transmission equipment

  16. Jobs In Fiber Optics • Designing components • Manufacturing fiber, lasers, etc. • Designing systems • Installing networks • Training and teaching
