Material Scattering Loss

 Rayleigh scattering causes 96 % of attenuation in optical fiber (

for both regions mentioned before ).
 As wavelength increase, Rayleigh Scattering decrease.

 Short wavelengths are scattered more than longer
wavelengths. Any wavelength that is below 800nm is unusable

for optical communication because attenuation due to Rayleigh

scattering is too high.
 Material Scattering can be reduced by improved fabrication /

manufacturing.
