ABSTRACT:
The optical fiber connector comprises two right circular drawn glass capillary cylinders, means for maintaining the cylinders in substantially fixed relative radial relation, and means for maintaining the cylinders in substantially fixed relative axial relation. The invention has a multiplicity of embodiments, including connectors functioning as variable attenuators, as fiber-to-fiber switches and connectors comprising an in-line filtering element. Connectors according to the invention can have very low insertion loss, are easily field-installed, can be easily and inexpensively manufactured, and are useful for single mode as well as for multimode fiber applications.
