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.

Abstract: A hermetically sealed media converter apparatus configured to operate in harsh high-pressure differential environments, such as deep marine environments, and oil and gas. A hermetically sealed media converter apparatus is provided having a vessel forming an inner chamber that is hermetically sealed from surrounding ambient environment outside the vessel. Media conversion circuitry is contained within the inner chamber. At least one hermetic electrical feedthrough is mounted on the vessel enabling a transmit wire and a receive wire to pass therethrough and connect to the media conversion circuitry, while maintaining the hermetic seal of the inner chamber of the vessel from the surrounding ambient environment. Similarly, a hermetic optical feedthrough also is mounted on the vessel enabling an optical fiber to pass therethrough and connect to the media conversion circuitry, while maintaining the hermetic seal of the inner chamber of the vessel from the surrounding ambient environment.

Abstract: A modular connector is provided having a connector plug, which may be inserted into an associated socket in a first longitudinal direction, a resilient leg, depending at a first end thereof from the connector plug, and having a depressible part, distal therefrom, depressible towards the connector plug, and a guard cover, configured to prevent access to the depressible part of the resilient leg in its direction of depression, but to permit access to the resilient leg in the longitudinal direction through an access aperture, the access aperture being aligned with the depressible part of the resilient leg on an axis parallel with the longitudinal direction, to allow depression of the resilient leg through the access aperture directly. Corresponding extraction tool and methods, loopback connector, blanking plug, keyed protrusions and notches, security gasket, and blanking plate and patch panel also are disclosed.
