TESTING CORE ALIGNMENT OF OPTICAL FIBERS USING ULTRAVIOLET LIGHT

摘要

In the connection of the opposed ends of two optical fibers, a method and apparatus for core alignment of the optical fibers, comprises placing the two optical fibers being connected so that their ends face each other, and illuminating at least the facing ends with a beam of ultraviolet light thereby causing the illuminated ends of the cores of the optical fibers which are doped with germanium (Ge) to emit light of a wavelength in the visible region and enabling the core alignment to be directly monitored visually with the aid of the visible light so emitted from the cores during the course of the core alignment.
