摘要：
An optical node apparatus that establishes an optical path between a first optical node and a second optical node in an optical network include a frequency modulation unit that superimposes a supervisory signal on a main signal by frequency-modulating the main signal, and a frequency demodulation unit that frequency-demodulates the supervisory signal superimposed on the received main signal.
