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.
