Attenuation Factor of an Optical Fibre Calculator
This CalcTown calculator calculates the attenuation factor of an optical fibre.
θi is the angle the ray makes with the fiber axis, before entering the fiber,
k0 is the wavenumber of the EM wave in vacuum,
n1 is the refractive index along the central axis of the fiber, and
n2 is the refractive index of the cladding.
