Moncef B. Tayahi 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: 7362979
    Abstract: An apparatus and method are provided for transmitting an optical duobinary signal using a low bandwidth modulator having a bandwidth of less than about 60% of the transmission bit rate of the transmitter. The modulator is adapted to provide low pass filtering for low pass filtered duobinary transmission in an optical fiber transmission system having residual dispersion.
    Type: Grant
    Filed: January 31, 2003
    Date of Patent: April 22, 2008
    Assignee: Lucent Technologies Inc.
    Inventors: Douglas M. Gill, David S. Levy, Xiang Liu, Moncef B. Tayahi, Xing Wei
  • Patent number: 7362980
    Abstract: An optical duobinary transmission system and method are provided for transmitting optical duobinary signals across an optical transmission link having residual dispersion. The system includes a transmitter having a low bandwidth modulator, adapted to provide filtering for low pass filtered duobinary transmission. The transmission link is designed such that the residual dispersion of the transmission link substantially compensates for signal distortion from the transmitter.
