摘要： An optical demultiplexer comprises a clock regenerating circuit for regenerating a clock signal for each optical signal channel from an optical multiplexed signal. An optical switch separates each optical signal channel from the optical multiplexed signal in accordance with the clock signal regenerated by the clock regenerating circuit. An identification information extraction circuit extracts identification information contained in each optical signal channel separated by the optical switch. A control circuit changes output destinations so that each optical signal channel is output to a designated destination in accordance with the identification information extracted by the identification information extraction circuit. The identification information is appended as identification data to a data signal represented by the optical signal, and the identification information extraction circuit extracts the identification data contained in the data signal reconstructed from each optical signal channel. A signal switching circuit is provided between outputs of the optical switch and output destinations, wherein the control circuit changes output destinations by changing connection relationships in the signal switching circuit between the outputs of the optical switch and the output destinations, for example, by changing the phase of the clock signal supplied to the optical switch.

摘要： An optical transmitter operates on the DPSH-IM (direct phase-shift and self-homodyne intensity modulation) principle. The optical transmitter slightly amplitude-modulates the modulation current of a laser diode using a low frequency signal and detects the modulated component from the optical output.
