An optical signal becomes increasingly distorted as it travels along the fiber.

I. 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 …
