Abstract
Using the cutback technique, the attenuation of four different silica
step-index fibers is measured in the very wide wavelength range of 190–1700
nm. The measured spectra are deconvolved into components describing Rayleigh
scattering, infrared losses, Urbach edge, anomalous loss, and different localized
absorptions using a least squares fit. The evaluated Urbach edge is compared
against results based on measurements on bulk glass samples and good agreement
between the two is found. Furthermore, the Urbach edge is found to contribute
significantly to the overall attenuation at communication wavelengths for
two of the four fibers investigated.
