  • Patent number: 10281659
    Abstract: We disclose a modular fiber-interconnect device that can be used in a ROADM to optically interconnect wavelength-selective switches and optical add/drop blocks thereof. An example module of the modular fiber-interconnect device has seventeen optical ports, each implemented using an MPO connector of the same type. The number of (nominally identical) modules in the modular fiber-interconnect device depends on the degree N of the ROADM and can vary, e.g., from two for N=4 to fourteen or more for N?20. A proper set of duplex optical connections within the ROADM can be created in a relatively straightforward manner, e.g., by running MPO cables of the same type from the wavelength-selective switches and the optical add/drop blocks of the ROADM to appropriate optical ports of the various modules of the modular fiber-interconnect device.

  • Patent number: 10275687
    Abstract: Data representing an image is received by an image recognition system. An image recognition system generates an image classification output distribution for a plurality of image features based on analysis of the data representing the image and training data stored for the image recognition system. One or more filters are applied to the image classification output distribution to obtain an updated image classification output distribution. A highest confidence value is selected from the updated image classification output distribution. A selected image feature associated with the highest confidence value is identified from the plurality of image features. Information associated with the selected image feature is obtained from a database and communicated to the user's device by the image recognition system.

  • Patent number: 10277321
    Abstract: The Quad Cell permits measurement of four quadrant signal powers simultaneously, metrics which are equal when the laser spot is at the desired zero location, at the center of the cell, the origin of the cells' axes. A control action acts upon the Quad Cell signals to move the laser spot toward the origin of the axes bisecting the four quadrants of the cell, moving the laser spot to the origin to achieve a null in the difference between these four signal levels.

  • Patent number: 10243658
    Abstract: Proposed is a method of receiving a WDM optical upstream signal in an optical access network. The WDM signal is filtered using a first optical filter yielding a first filtered signal. The first optical filter has a flat-top shaped pass-band transfer function. Furthermore the WDM signal is filtered using second optical filter yielding a second filtered signal. The second optical filter has a pass-band transfer function that is strictly monotonically increasing for wavelength values below a center wavelength of the transfer function and that is strictly monotonically decreasing for wavelength values above the center wavelength of the transfer function. Received upstream data is derived from the first filtered signal. An optical signal power level is derived from the second filtered signal an optical signal power level. Finally, it is indicated to an optical network unit a desired direction of wavelength shift in dependence on the derives signal power level.
