Optical waveguide (fibre optic, optical fibre) comprising a core glass and a cladding glass

摘要

The invention relates to an optical waveguide which comprises a core glass (KE) and a cladding glass (MA), at least one additional substance being provided. This additional substance (ZS) is arranged outside the cladding glass (MA) and contains at least one substance which has high reactivity towards hydrogen or water. This allows increases in attenuation to be avoided in a simple manner. IMAGE
