Dispersion:

  • Dispersion is the broadening of actual time-width of the pulse due to material properties and imperfections.

  • As pulse travels down the fiber, dispersion causes pulse spreading. This limits the distance travelled by the pulse and the bit rate of data on optical fiber.

  • In a fiber three distinct …
