conisder the step index fiber cable with n1=1.4, n2=1.3 and core redius=4micrometer
a_ show that the numerical aperture , NA=(n1^2-n2^2)^0.5
b_ what does the numerical aperture mean?
c_does the cable support single mode or multimode operation ? assume the wave length=1.6 micrometer
e_explain the effect of the graded index on the pulse dispersion?
