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.
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
