Tell me about Li-fi. The new coming future technology for transmission of data
  1. What is fiber optics?


  2. For landline telephones, when we speak, a wire cable carries the sounds from our voice into a socket in the wall, where another cable takes it to the local telephone exchange


  3. Cell phones or mobiles use a different technology hey use invisible radio waves. That's the reason this technology is called wirelessS


  4. Fiber optics works a third way.


  5. The idea originated while developing endoscopes in the 1950s to help doctors see inside the human body without having to cut it open first.


  6. How does Optical Technology work?


  7. A fiber-optic cable is made up of incredibly thin strands of glass or plastic known as optical fibers; one cable can have as few as two strands or as many as several hundred.


  8. Best example to understand how Optical Technology works? 101101 TEAT


  9. Light travels down a fiber-optic cable by bouncing repeatedly off the walls. Each tiny photon (particle of light) bounces down the pipe. For a normal beam of light, traveling in a clear glass pipe, it would simply leak out of the edges Air Glass Light ray Total internal reflection Source: BBC


  10. Light travels down a fiber-optic cable by bouncing repeatedly off the walls. Light hits glass at a really shallow angle (less than 42 degrees), it reflects back in again just like in a mirror. This phenomenon is called total internal reflection. Each tiny photon (particle of light) bounces down the pipe. For a normal beam of light, traveling in a clear glass pipe, it would simply leak out of the edges Air Glass Light ray Total internal reflection Img Source: BBC


  11. Optical fibers carry light signals down them in what are called modes. A mode is simply the path that a light beam follows down the fiber. So based on this, the different types are: and Single mode fiber Multi-mode fiber
