[[File:Silica core fiber minimum attenuation.jpg|thumb|Experimentally measured record low attenuation of silica core optical fiber. At 1550 nm wavelength attenuation components are determined as follows: Rayleigh scattering loss ~ 0.1200 dB/km, infrared absorption loss ~ 0.0150 dB/km, impurity absorption loss ~ 0.0047 dB/km, waveguide imperfection loss ~ 0.0010 dB/km.<ref>{{Cite journal |last=Khrapko |first=R. |last2=Logunov |first2=S.
