  • Tunable chromatic dispersion compensation device and method
    Patent number: 8380067
    Abstract: A tunable chromatic dispersion compensation device used to compensate chromatic dispersion of wavelength of at least one predetermined wavelength band of light signal is provided. The tunable chromatic dispersion compensation device comprises a chromatic dispersion compensator, and a controller. The chromatic dispersion compensator comprises at least a first chromatic dispersion compensation unit and a second chromatic dispersion compensation unit connected with the first chromatic dispersion compensation unit in series. The first chromatic dispersion compensation unit has a free spectral range, the second chromatic dispersion compensation unit has a free spectral range same as to that of the first chromatic dispersion compensation unit. Each chromatic dispersion compensation unit comprises an interference cavity. The controller comprises an inputting unit being configured for inputting a predetermined chromatic dispersion compensation information.

  • Configuration of a control system for an electrical switchgear assembly
    Patent number: 6882888
    Abstract: A method for configuration of a control system for an electrical switchgear assembly uses a primary device model for representation of primary devices, and a topology model of the switchgear assembly. In order to configure a first control system function, the first control system function is allocated to a primary device and to a field device, after which the primary device model and the topology model are used to automatically determine second control system functions which the first control system function requires during operation.
