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.
Claims12
An optical fiber stub assembly, comprising:
- a stub body having longitudinal configuration, a smaller inner chamber, a larger inner chamber, a first end, and a second end;
- a ferrule located within the larger chamber and extending out the second end of the stub body;
- an optical fiber having one end extending beyond the first end of the optical fiber and through the smaller inner chamber, the larger inner chamber, and a second end of the optical fiber is flush with an outer end of the ferrule that extends out beyond the second end of the stub body;
- and
- a vent is provided between an other perimeter of the ferrule and an inner surface of the larger chamber that passes from the larger inner chamber to an exterior of the stub body, wherein the vent enables gases generated during a sealing process of the optical fiber within stub body to escape.
