摘要：
In a polarization mode dispersion compensating apparatus for controlling polarization mode dispersion of an optical signal, a first optical monitor detects and outputs, based on an optical signal outputted from a first optical transmission line having a grating, a first detection signal indicating magnitude of waveform distortion of the first optical transmission line, and a second optical monitor detects and outputs, based on an optical signal output from a second optical transmission line having a grating, a second detection signal indicating magnitude of waveform distortion of the second optical transmission line. A calculator circuit calculates from the first and second detection signals an output signal. A controller controls a polarization controller based on the output signal from the calculator circuit.
