Loss increase in silicone-coated fibres with heat treatment

Abstract
Loss-increase characteristics for four kinds of silicone-coated optical fibres with heat treatment have been investigated OH ion absorption loss increase occurs by heat treatment above 250°C, and becomes marked in heat treatment at 500°C for GeO2-doped silica fibres. The others did not exhibit any loss increase at 1.39 μm due to OH ions. It was found, from the experiments, that the loss-increase characteristics in heat treatment depend strongly on the glass system in the fibre core.
