Compare pulse broadening for a silica fiber due to the three principal causes—modal distortion, material dispersion, and waveguide dispersion—in a step-index fiber. The core index is 1.470 and the cladding index is 1.455 at λ = 1 μm. Assume a LED source with a spectral width of 25 nm. The values of the parameters M and M′ are 43 ps/nm-km and 3 ps/nm-km, respectively.
a. Determine each separately by calculating δτ for a 1-km length of fiber.
b. Determine an overall broadening δτ for a 1-km length of fiber, using(δτ)2= (δτmod)2 + (δτmat)2 + (δτwg)2
