Abstract

An optical testing device is provided. The testing device includes a position sensing detector (PSD) having an optical sensing area that is optically responsive to a first range of wavelengths. The PSD receives a plurality of optical signals having wavelengths within the first range and emitted through a respective plurality of optical fibers and detects a plurality of positions where the optical signals impinged on the optical sensing area for determining array polarity. The PSD receives a plurality of first optical signals having wavelengths within the first range and detects the polarity and a plurality of optical intensities of the first optical signals. The testing device includes a photodetector that is optically responsive to a second range of wavelengths different than the first range. The photodetector receives a plurality of second optical signals within the second range and detects a plurality of optical intensities of the second optical signals.
