Abstract: An optical fiber stub having a first end and a second end, wherein the outer surface of the first end has a threaded surface, and a stop surface at a base of the outer threaded surface, a receptacle cap having a tubular body with a base end and a receiving end, wherein an inner surface of the base end is similarly threaded to the outer threaded surface of the first end, so that the base end of the receptacle cap can be screwed over and around the first end of the optical fiber stub. The receiving end of the receptacle cap includes two opposing flat surfaces on an outer surface of the receiving end, so as to enable a tool to grip the outer surface of the receiving end of the receptacle cap and unscrew the receptacle cap from the optical fiber stub.

Abstract: A vent or slot is provided between the ferrule and stub body that enables gases generated from the low melting glass sealing process of an optical fiber to the ferrule stub to escape, thus creating a stronger and more resilient and reliable seal between the optical fiber and low melting point glass and the stub body, creating the hermetic seal. Without such a vent, which is the conventional configuration, generated gases are forced into the molten glass during the sealing process, thus reducing the strength or resilience of the hermetic seal.
