How Fiber Optics Work

What are fiber optics?

• Fiber optics (n.) The science or technology of
  light transmission through very fine, flexible
  glass or plastic fibers
• Fiber optics (n.) A bundle of optical fibers.

Uses

• Fiber optics can be used for presentation of
  light, as in fiber optic lamps.
• Fiber optics also transmit data faster than
  copper wire because light travels faster than
  radio waves.
• Fiber optics can be used to transmit computer and
  telephone information.

Internal Reflection

• If the angle of incidence is great enough, the
  light is bent so much that it is reflected
  rather than transmitted through the new medium.
  This is called total internal reflection.

Total internal reflection, cont.

• By a continuous series of total internal
  reflections, laser light can be transported
  through and optic fiber. A tiny laser at the end
  of a fiber can shine light through a fiber,
  around a spool, and all the way to the end of the
  fiber.

How fiber optics are used

• Before data is sent, it is translated to binary
  form (if necessary).
• A laser or diode then flashes those 1s and 0s
  into a glass fiber. If the light is on, that's a
  1. If it's off, that's a 0.
• The light bounces through the glass fiber until
  it is received by another fiber optic modem.
• The fiber optic method works basically the same
  way as regular copper modems, but instead of
  electrical pulses, it uses pulses of light.

• Fiber optics can be used to transmit data in
  telephone, internet, live broadcasts, and is 20x
  faster than copper wire because it uses light
  instead of electrical pulses.
