Abstract:
A test controller of a transmitting-side optical wavelength multiplexing transmission apparatus of the present invention includes a wavelength tunable filter controller configured to control a center wavelength and a wavelength band of an optical signal that a wavelength tunable filter transmits; and a test transponder controller configured to control a wavelength band of a test optical signal generated by a test transponder and a wavelength interval between the test optical signal and the optical signal that the wavelength tunable filter transmits. A test controller of a receiving-side optical wavelength multiplexing transmission apparatus of the present invention includes a wavelength tunable filter controller configured to control a center wavelength and a wavelength band of an optical signal that a wavelength tunable filter transmits; and a test transponder controller configured to control a center wavelength and a wavelength band of a test optical signal received by a test transponder.
