ABSTRACT:
A connector to join like optical fiber waveguides in a manner designed to eliminate power losses at the connector resulting from misalignment or separation of the optical fiber end surfaces and/or resulting from dimensional differences in the respective diameters of the waveguide core and cladding which are inherent in the manufacturing process of like optical fibers and/or resulting from contamination of the end surfaces of the optical fibers during the joining process. Elimination of power losses within a connector from the above stated causes is achieved by aligning the cables to be joined within the connector and thereafter preventing movement of the optical fibers prior to endface cutting and during all subsequent joining operations, by precise targeting of each optical fiber port centerline with the center of its respective connector reflecting surface, by providing means to achieve a tight flush fit between the fiber end faces and the connector internal light transmitting components, by causing a slight convergence of the lightwave during its travel through the connector and by preventing human contact with the cable endfaces during the joining process.
