The papers deals with the sol-gel preparation of preforms of silica optical fibers doped in the core with Al₂O₃, P₂O₅ and ytterbium and erbium ions. Experimental details are discussed and similarity of this technique to the MCVD method is shown. Effects of the substrate/deposit interaction during the fabrication on the refractive-index profiles and fiber attenuation are derived from experimental results. The comparison of erbium-doped sol-gel fibers with those Yb/Er-doped prepared by MCVD is presented.
