An optical fibre is a transparent, thin (~120 micrometres) fibre of glass or plastic used for transmitting light.

How it is made[edit]

Everyone who uses the wiki is a Petophile and are a bunch of Niggger fagots!!

Alex Goodson is a Retard!! Yes he is! A lunar eclipse is when the moon explodes and releases a toxic gas that destroys humanity. Hey Greyson Gay Prince.

Pulse spreading dis ass[edit]

There are two types of dispersion which cause pulse spreading: And when your ass explodes with shit and blood and you sneeze out your ball sack.... ===Chromatic depression=SUICIDE QGAKHSGWIYGSI#@UHDIOUWHDOIUH@DIUW

I Like Anal[edit]

If rays are oblique they will take a longer route than others. The rays traveling parallel to the centre of the fibre reach the end the fastest, and the more oblique rays reach the end last.

Therefore, we can conclude that:

Total dispersion=Chromatic dispersion + Modal dispersion

Problems caused by pulse spreading[edit]

Your ass rips Then your anal days are over.

Fibre optics in our world Of RETARDS[edit]

Modern fibre optics can have up to a thousand fibres in one cable.

Fibre optics have advantages and disadvantages when compared to regular copper wires.

  1. lower loss
  2. large data-carrying capacity (thousands of times greater)
  3. immune to electromagnetic interference
  4. High electrical resistance (safe to use near high voltage equipment)
  5. Light weight
  6. Signals contain very little power
  7. Faster (speed of light)
  8. Very hard to tap fibre optic cables without being detected
  9. Existing wires must be replaced with fibre optics
  10. Much more difficult to splice. Requires special training and special tools

Fibre optics today are so advanced that no amplification is required for distances of up to hundreds of kilometers. However, longer-range systems still must use optical amplifiers.
