1.	How the power is lost in optical fiber through dispersion?explain.
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.Explanation:your problem's solution here.
