摘要： An optical receiver includes: a waveform distortion compensator (41) to perform an operation on digital signal representing an optical signal generated by an A/D converter to compensate for waveform distortion of the optical signal; a phase detector (42) to generate phase information representing sampling phase of the A/D converter; a phase adjuster (43) to generate digital signal representing an optical signal in which the sampling phase of the A/D converter is adjusted from an output signal of the waveform distortion compensator using the phase information; a demodulator (44) to generate a demodulated signal from the output signal of the phase adjuster; a phase controller (45) to control the sampling phase of the A/D converter; a peak detector (48) to detect a peak value of the phase information while the sampling phase of the A/D converter is controlled by the phase controller; and a compensation controller (49) to control the waveform distortion compensator using the peak value.

摘要： A frame generating apparatus accommodating a client signal in an optical data transfer unit frame with a higher bit rate than the client signal includes a deserializer, a plurality of generic mapping procedure circuits, and a serializer. The deserializer deserializes the client signal into parallel signals, the number of parallel signals corresponding to the number of tributary slots used in the optical data transfer unit frame, The plurality of generic mapping procedure circuits inserts data and stuff into a frame accommodating portion of the optical data transfer unit frame based on a difference in the bit rate between the client signal and the optical data transfer unit frame, The serializer serializes the parallel signals output from the plurality of generic mapping procedure circuits.
