Abstract: An optical fiber terminus that comprises a one-piece body that comprises an inner tube that defines an inner bore configured to receive an optical fiber. The inner tube has first and second opposite ends and is configured to allow insertion of the optical fiber at the first end. An outer spring member substantially surrounds the inner tube. The outer spring member has first and second end sections and an intermediate section therebetween. The intermediate section has a plurality of windows which expose portions of the inner tube. When a force is applied to the first end of the inner tube, the windows of the outer spring member are compressible such that the windows collapse.

Abstract: A durable, low loss splice connection for optical cables includes two ceramic optical fiber guide members which are held in axial and angular alignment by an alignment sleeve, and in butt joint intimate contact by a spring tension clip. The connection is mechanically and environmentally sealed by a heat shrink tube having an interior diameter coated with hot melt adhesive.

Abstract: An alignment bushing (40) having a frusto-conical entranceway (44,46) at each of its opposite end faces (41,43) with each entranceway receiving a frusto-conical lens (30) terminted to an optical fiber cable (16,26), the bushing optically aligning and coupling an optical signal passed between a fiber in each with each lens having its focal point (31) coaxially rearward of a hemispherical nose portion of the lens and abutting the fiber end. The frusto-conical cross-section defining the entranceway and lens conform identically to assure coaxial seating.

Abstract: This invention is a lens type fiber optic connector that has a lens holder assembly (70) releasably mounted (54, 78) within the bore of an insert (55). This arrangement provides for quick and easy installation, repair or replacement of a lens (10) or defective optical fiber (81) without the need to replace or disassemble the entire connector.
