  • Power level management in optical networks
    Patent number: 7609964
    Abstract: In an optical communication network, optical communication nodes exchange information detailing power level variations to support management and administration of optical communications. This exchange of information permits nodes to determine aggregate power level variations over light paths to support operations such as selection from available light paths and configuration of optical communication characteristics.
    Type: Grant
    Filed: April 30, 2007
    Date of Patent: October 27, 2009
    Assignee: Fujitsu Limited
    Inventors: Kumar Vijay Peddanarappagari, Jamil Omar-Hatem El-Reedy, Emir Catovic
  • Optical signaling to share active channel information
    Patent number: 7327954
    Abstract: A method for optical supervisory signaling includes determining a wavelength channel status (WCS) value, a wavelength channel failure (WCF) value, and a wavelength channel lit (WCL) value for each one of multiple data channels services by an optical communication node. The method further includes communicating the values to a second optical communication node.

  • Method and system for automatically setting gain for an amplifier in an optical network
    Patent number: 7151895
    Abstract: A method for automatically setting a gain for an amplifier in an optical network includes transmitting, from a source proximate an upstream amplifier coupled to an optical span, a stable signal over the optical span. The method also includes using the stable signal at a downstream amplifier coupled to the optical span to automatically set a gain of the downstream amplifier.
