Abstract
An optical fiber alignment apparatus for leveling respective distal ends of a plurality of optical fibers prior to commencing a polishing process. The apparatus includes an aligning device having a plurality of receptacles for securing the corresponding plurality of optical fibers such that distal ends of the optical fibers extend below the base of the aligning device. A sensor array contacts the distal ends of the optical fibers and generates sensor alignment signals indicating the position of the fiber distal ends extending below the aligning device relative to a horizontal reference plane. A monitor receives and displays digital signals corresponding to the sensor alignments signals. Those optical fibers that are not aligned are then adjusted to until all the fibers are aligned and leveled with respect to the horizontal reference plane as viewed on the monitor. The precision of the horizontal alignment offered by the sensor array and digital monitor display allows the subsequent polishing process to be performed with a greater degree of reliability and consistency.
