摘要： Before wiring of a physical wiring changing-over switch is switched, a communication suspension instructing unit in a controller sends a signal to instruct IT devices connected to the physical wiring changing-over switch to suspend communications for a certain period of time and hold the communication bit strings to be transmitted in a temporary storage area. The signal is sent via an exclusive control line between the controller and the IT devices.

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.
