//Caption:Program to determine the loss limit and the chromatic dispersion limit of a high performance SMF FOC
//Example 8.2
//Page 389
//Refer figure 8.2 on page 385
disp('The attenuation of single-mode fibre operating at 1300nm is approximately 0.35dB/km. Thus,')
Pin=42//input power = 42dB
A=0.35
LL=(Pin/A)//Loss Limit
disp('Using 250 Gbps-km as BDP of a silica single-mode fiber, the chromatic dispersion limit is determined as')
Cd=(250000/417)//Chromatic dispersion limit
//Result
//Loss Limit = 120 km
//Chromatic Dispersion Limit = 599.52 = 600 km
