Abstract
A process and tool for reshaping and resizing grooves that were pre-formed in a pair of ferrules halves of an optical fiber ferrule. The pre-formed grooves are further subject to a separate, subsequent reshaping and resizing step using the tool and a gauge that may be a bare section of optical fiber or a pin. The ferrule halves are aligned, and using the pre-formed grooves as guides for the gauge optical fiber or gauge pin, the ferrule halves are compressed together with the gauge optical fiber or gauge pin therebetween, thereby reshaping and resizing the respective grooves on the ferrule halves. After reshaping and resizing, the resultant groove that is finally formed on each ferrule halve would be precisely shaped, sized and located with respect to the external alignment surface of each ferrule halve. The ferrule halves may be used to terminate an optical fiber cable.
