Abstract: A wavelength cross-connect device performs a relay process in which multiple wavelength signal light beams that have been transmitted in multiple bands from a plurality of paths and demultiplexed into optical signals in the respective wavelength bands for each path are amplified, are switched to paths by contention WSSs, and are output to paths on the output side. A WXC unit performs the relay process on an optical signal in a specific wavelength band. An input-side conversion unit that converts a wavelength band other than the specific wavelength band into the specific wavelength band is provided on the input side, and an output-side conversion unit that converts the specific wavelength band after the conversion into the wavelength band prior to the conversion is provided on the output side. A directly-input optical signal in the specific wavelength band is directly output after the relay process at the WXC unit.

Abstract: An optical node device includes a transmission transponder, WSSs, a beam splitter, and a monitoring transponder. The transmission transponder transmits an optical signal via an optical path set in an optical fiber. The WSSs ultiplex, on the transmitted optical signal, a monitoring control signal for performing optical path tracing that is confirmation of conduction along the optical path. The monitoring transponder measures and monitors the optical power of the monitoring control signal multiplexed into the optical signal branched by the beam splitter, and further monitors whether the monitored optical power is equal to or higher than a predetermined level indicating normality of the optical path.
