Patents by Inventor Piergiovanni Matrona

Piergiovanni Matrona 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 communication system
    Patent number: 7231146
    Abstract: Communicating a signal includes receiving the signal at a primary device of a switching system, where the primary device is associated with a primary path along which the signal is propagating. A primary overmodulation signal associated with the primary path is generated. The absence of the primary overmodulation signal is detected, and an operating signal is sent from the primary device to a secondary device of the switching system, where the secondary device is associated with a secondary path. The operating signal operates to initiate propagation of the signal along the secondary path.
    Type: Grant
    Filed: April 30, 2003
    Date of Patent: June 12, 2007
    Assignee: Cisco Photonics Italy S.r.L.

  • Optical communication system
    Patent number: 6580530
    Abstract: An optical communication system for communicating at least a first optical system. The optical communication system includes a first primary guided optical path and a first secondary guided optical path, through each of which the first optical signal is configured to propagate. A first primary optical amplifier is provided in the first primary guided optical path and is configured to transmit an overmodulation frequency of the first optical signal. A first secondary optical amplifier is provided in the first secondary guided optical path and is configured to transmit the overmodulation frequency of the first optical signal. A controller controls propagation of the first optical signal from the first primary guided optical path to the first secondary guided optical path based on the detected presence of the overmodulation frequency.
