Vacuum optical fiber connector and optical fiber terminal structure

摘要

A vacuum optical fiber connector includes a port flange attached to a vacuum flange for housing a first waveguide connector to which an optical fiber bundle is attached, an optical transparent body placed on the outside of the port flange, and an attachment member formed with a fit shape relative to the port flange for housing a second waveguide connector to which an optical fiber bundle is attached. The first and second waveguide connectors are positioned at least in two directions orthogonal to an optical axis with optical coupling of the first and second waveguide connectors.
