//Caption:Program to determine the loss limit and the multimode dispersion limit of a graded index FOC
//Example 8.1
//Page 388
//Refer to figure 8.2 on page 385

disp('The attenuation of a multimode fiber operating at 820nm is approximately 3db/km. Thus,')
A=3//attenuation
LL=(Pin/A)//Loss Limit
disp('Using 2 Gbps-km as typical BDP of graded index multimode fiber, the multimode dispersion distance is determined as')
Dl=(2000/90)//Dispersion limit
//Result
//Loss Limit = 14 km
//Dispersion Limit = 22.2 km
