Diameter of Fiber

LaTeX Go Diameter of Fiber = (Wavelength of Light*Number of Modes)/(pi*Numerical Aperture)

Power Loss in Fiber

LaTeX Go Power Loss Fiber = Input Power*exp(Attenuation Coefficient*Length of Fiber)

Fiber Attenuation Coefficient

LaTeX Go Attenuation Coefficient = Attenuation Loss/4.343

Number of Modes using Normalized Frequency

LaTeX Go Number of Modes = Normalized Frequency^2/2

Beat Length Formula

LaTeX Go

Beat Length = Wavelength of Light/Modal Birefringence Degree
L_b = λ/B_m
