ABSTRACT:
Disclosed is an apparatus for testing an array of optical fibers. According to the invention, modulated light is projected through individual fibers of a fiber array onto a photo-sensitive position sensor. The photo-sensitive sensor will provide position information relative to the position of the light projected upon its surface to a system computer. The positions of the optical fibers within the array relative to each other may thus be found. A loop is introduced into the optical fibers to lower the wavelength at which the fiber is multi-moded. The actual positions of the optical fibers are compared to desired positions and the fiber array is accepted or rejected based on whether it meets predetermined limits.
