Abstract: A fiber optic connector including a ferrule surrounding an optical fiber and a hub engaging the ferrule. The hub includes a front portion having first and second opposing surfaces and first and second tapered regions extending from the first and second opposing surfaces to a front face. A housing includes an anti-rotation seat configured to engage the first and second opposing surfaces, the anti-rotation seat including parallel first and second contact lines positioned at a front of the anti-rotation seat. A spring within a chamber of the housing biases the ferrule through a bore in the front of the housing. The first tapered region of the hub engages the first contact line and the second tapered region engages the second contact line when the hub and ferrule are in a first rotational position so that the optical fiber is maintained at a known orientation with respect to the connector.

Abstract: An optical fiber cable assembly comprising an optical fiber slidably enclosed within a hollow tubing, both the fiber and the tubing having corresponding first and second ends. The cable is terminated with the first and second ends of the tubing and the fiber constrained with respect to each other such that fiber and the tubing are approximately the same length when the cable is at a first temperature. The tubing is made of a material which contracts more than the optical fiber when the cable is exposed to temperatures below the first temperature, such that the fiber is longer than the tubing and excess fiber length is formed. An intermediate portion of the tubing permits the excess fiber length to accumulate without bending in a radius smaller than a minimum bend radius.

Abstract: The present invention relates to bulkhead adapters for optically connecting two strands of optical fibers and including a length of optical fiber within the adapter for attenuating signals passing from one fiber to the other. The attenuation optical fiber is held within an attenuation hub inside the housing of the adapter. Attenuation of optical fiber signals transmitted through the adapter may be provided by the optical fiber, by an offset fusion of two optical fibers, by an airgap between two optical fiber segments, by the inclusion of a filter between two optical fiber segments, or by other structures. When an optical fiber with a connector is inserted into the adapter, the optical fiber is placed in optical contact with the attenuation optical fiber of the attenuation hub. The adapter can be inserted through an opening in a bulkhead so that optical fiber from one side of the bulkhead can be attached to optical fiber on the second side of the bulkhead.

Abstract: The present invention relates to a fiber optic device for the optically connecting optical fiber. The device consists of fiber optic connectors holding the terminal ends of optical fiber in ferrules and an adapter for receiving fiber optic connectors. The adapter includes a sleeve within a longitudinal opening which aligns the ferrules and the terminal end of the optical fiber held by the ferrules. Within the sleeve is placed an attenuator which extends across the longitudinal opening in the sleeve and is held at an angle to the longitudinal axis of the opening by slots in the sidewall of the sleeve. The angle at which the attenuator is held may be perpendicular or non-perpendicular to the longitudinal axis of the sleeve. The sleeve is further prevented from rotating within the adapter by pockets formed in the inner wall of the longitudinal opening engaging extensions of the attenuator beyond the sidewall of the sleeve.
