Abstract

The use of silica fibers as a broad-band transmission medium in telecommunications is growing very rapidly. The information carrier is light in the near-IR region, preferably at the wavelengths 0.85, 1.30, and 1.55 μm. The reasons for the use of these wavelengths are (1) the occurrence of relative minima in the absorption spectra of silica and, in consequence of this, (2) the development of suitable optical sources and detectors especially adapted to these wavelength windows. In fiber optics terminology the terms "transmission loss" or "attenuation" mean absorbance. <i>A.</i> For an optical fiber this is one of the most important parameters. In telecommunications the spectral attenuation <i>a</i> = 10 <i>A/b</i> is measured, where <i>b</i> means sample pathlength; <i>a</i> is measured in decibel/km (dB/km).
