ABSTRACT:
An optical fiber connector comprising a fiber terminus piece with a longitudinal bore through which a bare fiber is inserted. The fiber terminus piece with an appropriately prepared fiber therein is held coaxially aligned with a mating terminus piece. The fiber terminus piece comprises, on its mating face, a "pedestal," typically having truncated-cone shape, extending outwardly from the plane of the face, with the fiber terminating within the face of the pedestal, whereby the area of potential contact between the mating terminus pieces is substantially reduced. The pedestal material advantageously is somewhat compliant, of compressive modulus between about 10.sup.4 and 10.sup.6 psi at 25.degree. C., preferably between about 10.sup.5 and 5.10.sup.5 psi. The novel geometry results in improved performance, as compared to prior art connectors having flat mating faces. Disclosed are also connectors comprising advantageous means for transferring axial loads from a cable strength member to the connector body.
