摘要： Methods and apparatus for maintaining a pre-determined ratio of a pilot tone power and a total mean optical power of an optical signal are provided. One apparatus includes an optical source coupled to provide an optical signal in response to a DC bias and an AC bias corresponding to a pilot tone signal. A processor is coupled to compute each of an AC component and a DC component of the optical signal from the same digitally sampled signal. A feedback control is coupled to vary at least one of the DC bias and the AC bias in accordance with a difference between a pre-determined value and a ratio of the AC and DC components.

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： Methods and apparatus for managing static and dynamic optical network configurations to enable mapping an actual optical network or validating an expected optical network are provided. In one embodiment a validation method includes the step of selecting an optical path having a plurality of nodes from a database defining an expected optical network. A list of detected pilot tones from each node associated with the selected optical path is generated. An expected list of pilot tones associated with each node of the selected optical path is generated. Comparison of the expected and detected lists identifies any mismatched nodes. Another method includes the step of setting a first pilot tone source to have a first pilot tone value. All other network pilot tone sources are set to have another pilot tone value. An optical path associated with the first pilot tone source is then mapped by identifying each node of the network having the first pilot tone value. Extraneous information can be applied to provide greater assurances as to likelihood of possible actual optical paths during the mapping process. Methods of re-configuring network pilot tone sources to preserve mapping and validation abilities when adding nodes, adding optical paths, or even adding another network to a pre-existing network are also provided.

摘要： Apparatus and methods are described which are useful for determining a distance between an RFID tag and an RFID tag reader. In various embodiments, signals backscattered from a singulated tag over a range of frequencies are evaluated for in-phase I and in-quadrature Q signal components. The I-Q data is processed to determine phase delay angles associated with each signal frequency. The phase delay data can be processed by a sum of squared errors method or Fourier transform method to determine a distance to the singulated tag. The methods can also be used to determine any of a location, a radial velocity, a directional velocity of the singulated tag, and proximity of the singulated tag to a second tag.

摘要： A method and system provide for sensing multiple wavelengths simultaneously in a single wavelength sensing device. The system may have a plurality of laser signals and a plurality of identifiable modulation signals. A respective laser signal of the plurality of laser signals is combined with a respective identifiable modulation signal of the plurality of identifiable modulation signals so that each of the laser signals is identifiable. A combined optical signal is then formed from the modulated laser signals. A sensor has an input port that receives the combined optical signal. The sensor identifies, for each of the modulated laser signals, a respective laser signal via the identifiable modulation of the respective modulated laser signal.
