Abstract
An optical plug connector for an optical measuring device between an internal light waveguide optical fiber and an external light waveguide optical fiber maintains a distance d between the ends of the fibers which is greater than the coherence length of the light to be transmitted through the coupling. In this manner, in spite of the presence of the air gap, interference phenomena are avoided.
