A light pulse with wavelength 850 nm passes through a single-mode silica fiber.

(a) Determine the time spread of the pulse per unit length due to material dispersion if the spectral width is 20 nm.

(b) Repeat if the spectral width is 2 nm.

Explanation:

answer:

explain:

we don't have any choices.

answer:

design model: consists of design geometry; can be 2d or 3d; typically has a black background.

design files: drawing created with microsoft expression design, a drawing and design program for windows; may contain both vector and raster graphics; can also include multiple layers and various image effects.

elements: an element is a single part of a larger group.
