| 摘要 |
A node device includes a data pattern generator configured to generate different fixed patterns for a plurality of ports to insert the generated fixed patterns into optical signals output from a plurality of optical transmitters, an optical switch configured to switch outgoing paths of the optical signals to output the optical signals as a multiplexed signal from one of the ports, a detector configured to detect a frequency spectrum of the multiplexed optical signal, and a management part configured to monitor a peak frequency of the detected frequency spectrum to detect an erroneous optical fiber connection associated with the optical transmitters based on peak frequencies corresponding to the different fixed patterns for the respective ports.
