WebIn commercial fibers operating between 700-nm and 1600-nm wavelength, the main source of loss is called Rayleigh scattering. As the wavelength increases, the loss caused by Rayleigh scattering decreases. If the size of the defect is greater than one-tenth of the wavelength of light, the scattering mechanism is called Mie scattering. 1.
