Answer to Question #241003 in Electrical Engineering for Dhr

Question

Consider a fused silica single-mode fiber that is 1 km long. Find the material dispersion component of the pulse spread if Delta lamda is 3.0 nm and the operating wavelengths are 800 nm, 900 nm, 1300 nm and 1500 nm.

Answer 1

Presented in the case are:

1.     Single-mode fiber of 1KM

2.     Delta lamda: 3.0 nm

3.     Operating wavelengths are 800 nm, 900 nm, 1300 nm and 1500 nm.

Material dispersion is calculated using the formula:

When we substitute this, we find material dispersion of
