Abstract

The OH absorption spectrum between 1200 and 1550 nm has been analyzed in plasma chemical vapor deposition (PCVD) optical fibers. Using these data, a model for the structure of the spectrum is developed so that the wings and tails can be taken into account properly. This model is able to correlate almost quantitatively the OH peak absorption intensity at ~1380 nm with the intensity of the absorption tails in the transmission windows around 1300 and 1550 nm. Three different OH species and two combination bands are involved in the model. An attempt is made to identify the spectral components, with special OH environments on a microscopic scale
