    Abstract: An apparatus for measuring the optical-signal-to-noise ratio (OSNR) of an optical system is adapted to function in single channel or in multi-channel wavelength division multiplexed optical communication systems. An optical signal spectrum and a center frequency characterize the optical signals. A narrow-band notch filter, realized by an in-fiber Bragg grating, is utilized to remove a component of the signal so the remaining signal can be measured. When multiple channels are present, a bandpass filter is used to select the part of the multiplexed signal to be measured. Both the narrow-band notch filter and the bandpass filter can be tunable to further extend the capabilities of the system. Two detectors are utilized with the power in the channel being measured by a low-gain detector and the power in the noise being measured by a high-gain detector. A processor receives the detector outputs, calculates OSNR, and controls the tunable components.

    Abstract: Embodiments of present invention provide a method for checking integrity of a device selection process. The method includes placing multiple devices in a device tray that has multiple cells arranged in a matrix of M-rows and N-columns; separating the multiple devices into a first group and a second group; causing a machine to memorize locations of at least the first group; removing the second group from the device tray; after the removing, causing the machine to capture an image of devices remaining in the device tray and identify locations of the remaining devices based upon the image; comparing locations so identified with locations of the first group of devices memorized by the machine; and taking a corrective action when a discrepancy is found between the locations identified and locations memorized. An apparatus for performing the above method is also provided.
