Mark D. Tremblay 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).

  • Optical fiber transmission system with noise loaded idler channels
    Patent number: 6999683
    Abstract: A wavelength division multiplex optical system includes a WDM combiner to provide a source signal, at least one transmitter coupled to an input of the WDM combiner, a broadband noise source, and a filter coupled between the broadband noise source and another input of the WDM combiner. In one embodiment, the filter is an optical notch filter. In an alternative embodiment, the filter includes a WDM demultiplexer coupled through plural filters to provide a plurality of noise signals and a WDM multiplexer coupled through at least one filter of the plural filters to respective noise signals.
    Type: Grant
    Filed: December 30, 2003
    Date of Patent: February 14, 2006
    Assignee: Tyco Telecommunications (US) Inc.
    Inventors: Franklin W. Kerfoot, III, Matthew X. Ma, Mark D. Tremblay, Wolfgang Schlosser
  • System and method for automatic optimization of optical communication systems
    Patent number: 6973601
    Abstract: A method and apparatus for maintaining an established error count for data transmitted on a wavelength division multiplexed (WDM) optical communication network. Error counts from a forward error correction (FEC) code are monitored and operational parameters are automatically adjusted in response to the error counts, thereby achieving system optimization in an automated manner.
