    摘要: Methods and apparatus for managing an optical network using pilot tones are provided. One method includes selecting an optical path having a plurality of nodes from a database defining an expected optical network. A detected list of pilot tones associated with each node of the selected optical path is generated. An expected list of pilot tones associated with each node of the selected optical path is generated. The detected and expected lists are compared to identify any mismatched nodes.

    摘要: A pilot tone generator receives optical energy from an optical communication medium carrying a plurality of optical signals. Each optical signal carries data modulated at a unique wavelength and further modulated with a unique identification signal. The identification signal has an amplitude corresponding to an optical power of the associated optical signal. The pilot tone receiver detects each identification signal from the optical energy received and determines its corresponding amplitude. The pilot tone receiver calculates the optical power of each optical signal in the optical energy in response to the amplitude of the associated identification signal.

    摘要: A system for power supply synchronization in an Radio Frequency Identification (RFID) reader is shown and described. In one embodiment, the system includes one or more switched mode power supply devices and a signal generator. Each of the switched mode power supply devices provides power to at least one component of the RFID reader. The signal generator transmits a synchronization signal of a controlling frequency to each of the one or more power supply devices. In one embodiment, the system includes a signal processing unit that is configured to reject one or more spectral components from the output of the RFID reader.
