Patents by Inventor Sheldon Louis Sun

Sheldon Louis Sun has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7434116
    Abstract: A testing apparatus for testing optical components includes an optical transmitter, an optical attenuator, an optical power meter and an optical receiver which are substantially rigidly coupled in a fixed relation to each other within a single housing. The system permits the common control of all the optical components such that calibration, testing and troubleshooting may be performed using a common user interface. The testing apparatus is unitary, compact and portable, and is a much more robust testing apparatus than conventional schemes.

  • Patent number: 7187435
    Abstract: An error analysis tester for an optical component includes an optical transmitter, an optical attenuator, a port, a receiver, a processor and a graphical display. The optical transmitter and optical attenuator produce a test signal at a plurality of selected optical power levels. The port is configured to output the test signal to the optical component and to receive a version of the test signal from the optical component. The receiver determines errors in the received version of the test signal. The processor determines data points of a function associated with an error rate at each of the selected power levels and a line corresponding to the data points. The graphical display produces a visual plot of the data points and the corresponding line.

  • Patent number: 6956642
    Abstract: A device and method that performs error analysis of an optical component. An optical transmitter transmits a test signal at a plurality of selected optical power levels. A port outputs the test signal to the optical component, and then receives a version of the test signal from the optical component. A receiver determines errors in the received version of the test signal. A processor determines an error rate at each of the selected optical power levels based on the determined errors, and also determines an uncertainty range for each determined error rate. An interface provides indication of the determined error rates in relation to the determined uncertainty ranges.
