摘要： A response-time storing unit stores a response time from start of output of driving force required for switching paths until stabilization of the driving force, for each of the paths to be connected. A driving-force correcting unit corrects output level of the driving force, starting correction of the output level of the driving force after the response time for a specified path stored in the response-time storing unit has passed since output of the driving force required for switching to the specified path started.

摘要： A radio-frequency-signal generator generates an RF signal. An optical monitor monitors a first intensity of a reference signal and a second intensity of a drop signal. A reference-frequency determining unit determines, based on the first intensity, a first frequency of an RF signal that causes the AOTF to output the reference signal. A temperature detecting unit detects a temperature of the AOTF. A frequency calculating unit calculates a second frequency of an RF signal that causes the AOTF to output a drop signal of a desired wavelength. A control unit controls the RF-signal generator to generate the RF signal of the second frequency calculated.

摘要： An optical communication apparatus for controlling the operating point of an optical modulation unit appropriately. An adding unit adds a bias voltage and a pilot signal. An optical modulation unit modulates light by an electrical signal, performs further modulation by a signal from the adding unit, and outputs an optical signal. A monitor unit monitors the level of the optical signal and outputs a monitor signal. A reference signal output unit outputs a reference in phase with the pilot signal contained in the monitor signal. A synchronous pilot-signal detection unit performs synchronous detection of the monitor signal by using the reference. A synchronous noise detection unit extracts noise from the monitor signal and performs synchronous detection of the noise by using the reference. A control signal output unit subtracts the synchronous detection value of the noise from that of the monitor signal, and outputs a control signal.

摘要： A drop-type AOTF is used as a configuration for removing from a through signal an optical signal having the same wavelength as that of an optical signal to be added. To the drop-type AOTF, RF signals are input to always select all of wavelengths, and an RF signal is not input for a wavelength desired to be rejected. As a result, the optical signal having the wavelength for which the RF signal is stopped is not selected by the drop-type AOTF, and cannot pass through. Since there is only one RF signal whose input is stopped, a “drawing effect” does not occur, and control of an optical add/drop device is simplified. Additionally, since high-speed switching can be made, and a wavelength to be added can be varied, restrictions are not imposed on a network configuration.
