Abstract
An improved optical fiber connector is described in which the necessity for tight tolerances on concentricity, sleeve diameters and sleeve bores is eliminated in a low-cost easily constructed and optically low loss device. A single precision tunnel device is used to provide alignment and abuttment between two free optically transmissive fibers. Cooperative mechanism between the tunnel device and fiber holders is utilized to guide the fiber into the precision tunnel.
