Question

how the power is lost in optical fiber through dispersion?explain.

Answer 1

Answer:

Dispersion is an effect where different frequencies have a different refractive index and hence a different speed.

If multiple waves are sent at different frequencies at the same moment then when they arrive they will not all arrive at the same moment.

So the wave is spread over time and less of it is available at any given moment.

ie there is a loss of signal power at any given instant.

Answer 2

Answer:

If the light signal is not perfectly monochromatic and contains different wavelengths, dispersion takes place in the fibre. A narrow beam of wavelengths is refracted in different directions and the light spread. ... Hence, the power is lost during the transmission in optical through dispersion
