problem 6: What is dispersion shifted and dispersion flattened fibers.

problem 7: Two step index fibers exhibit the given parameters:

a) A multimode fiber with core refractive index of 1.5, a relative refractive index difference of 3% and an operating wavelength of 0.82um.

b) An 8um core diameter single mode fiber with a core refractive index similar as (a), a relative refractive index difference of 0.3% and an operating wavelength of 1.55um. Find out the critical bending radius of curvature at which large bending losses take place in both cases.

problem 8:  A multimode graded index fiber exhibits total pulse broadening of 0.1us over a distance of 15 Km. Estimate:
