Abstract: An optical fiber terminus includes an elongated body with a passage along a central axis for receiving a portion of an optical fiber cable therethrough and an indexing section. A ferrule is secured to the body and has an end portion of said optical fiber cable therein. A collar is positioned on the elongated body and has an engagement section for engaging the indexing section. The collar is movable along the axis between first and second operative positions. In the first operative position relative rotational movement between the collar and the body is prevented and in the second operative position the collar may rotate relative to the body. A biasing member is provided to bias the collar towards the first operative position.

Abstract: An optical fiber connector includes a connector housing having first and second generally parallel, spaced apart first and second faces and at least one generally cylindrical receptacle for removably receiving an optical fiber terminus therein. An optical fiber terminus is located within the receptacle and includes an elongated body with a passage along a central axis for receiving a portion of an optical fiber cable therethrough. The body further includes an indexing section, and a ferrule secured to the body and having an end portion of said optical fiber cable therein. A collar is positioned on the elongated body and has an engagement section for engaging the indexing section. The collar is movable along the axis between first and second operative positions. In the first operative position relative rotational movement between the collar and the body is prevented and in the second operative position the collar may rotate relative to the body.

Abstract: A high-performance connector for optical fibers includes a cylindrical ceramic or metallic ferrule installed in a structure. This structure is positioned in a non-plastic (metallic system) base member to form a fiber holder. This overall generally cylindrical structure includes a small passageway along its central axis for holding an optical fiber. This entire structure is mounted within the non-plastic housing that includes an opening at one end thereof from which the ceramic ferrule protrudes. A cylindrical spring that is integral to the ferrule support structure and interacts with an interior surface of the surrounding structure via a secondary piece of the cylindrical structure urges the ceramic ferrule outward from the opening in the housing. The housing includes a metallic leaf-spring latch which is located on a single surface thereof, which is manually operable and used to lock the connector to an associated receptacle.
