Consider a multimode fiber with a core diameter of 100 µm, core refractive index of 1.4750, and a cladding refractive index of 1.4550 both at 850 nm. Consider operating this fiber at λ = 850 nm. (a) Calculate the V-number for the fiber and estimate the number of modes. (b) Calculate the wavelength beyond which the fiber becomes single mode. (c) Calculate the numerical aperture. (d) Calculate the maximum acceptance angle. Consider a multimode fiber with a core diameter of 100 µm, core refractive index of 1.4750, and a cladding refractive index of 1.4550 both at 850 nm.
