    摘要: In an optical switch controller, in order that residual vibration at movement control of a movable body such as a tilt mirror can be reduced and controlled with high accuracy, a processing unit outputs a driving signal for controlling the angle of the tilt mirror, the driving signal is D/A converted by a D/A converter and then is changed to a high-voltage signal by a high-voltage amplifier to be supplied to the tilt mirror, the electrostatic capacity of the tilt mirror changes corresponding to angle change of the tilt mirror, a mirror-angle detecting unit detects the electrostatic capacity and feeds back it as a correction value to a processing unit, and the processing unit corrects the driving signal using a correction value obtained when the angle of the tilt mirror is actually changed.

    摘要: In an optical receiver, a light receiving element receives the optical packet signals and converts the optical packet signals to electrical signals. A bias voltage supply section supplies bias voltage to the light receiving element. A monitoring section monitors an input level of each optical packet signal or each electrical signal and transmits a monitored value to the bias voltage supply section. In addition, the bias voltage supply section temporarily increases the bias voltage according to magnitude of the monitored value after an end of receiving of each optical packet signal.

    摘要: A communication terminal apparatus receives a management signal at a bit rate A and a data signal at a bit rate B (B=A×M) through the same line. The communication terminal apparatus includes a signal regenerating unit, a management signal converting unit, a timing control unit, and a data signal obtaining unit. The signal regenerating unit regenerates a signal transmitted through the line as a signal of a bit rate C (C=A×N). The management signal converting unit converts N bits of the regenerated signal into the management signal of one bit. The timing control unit controls timing for obtaining a data signal based on the management signal. The data signal obtaining unit obtains the data signal according to timing control of the timing control unit.

    摘要: In an optical telecommunication system in which an intensity of an arriving optical signal is different for each packet, detected is an optical intensity for each packet with little error. For this purpose, contrived is to detect an average optical intensity across header parts for each packet by focusing on the fact that the header part comprising the preamble and delimiter of a packet is in a bit pattern which includes approximately the same numbers of “0” and “1”.
