Abstract
This paper presents data concerning two processes by which a quartz fiber lightguide interacts with water vapor. When a lightguide is fabricated, the moving fiber can adsorb water vapor from the ambient atmosphere, and, after a metallic leak-proof cladding has been formed, a process occurs by which water molecules migrate into the bulk of the quartz glass. The latter is accompanied by an increase of the bending strength of the quartz fiber in time.
