Summary:Provided is a technology for simultaneously monitoring a plurality of relay devices. A relay device 1 comprises a superimposing unit 2 and a monitor unit 3. The relay device 1 is interposed on an optical transmission path between optical communication devices that send and receive an optical signal, and has a function for relaying the optical signal flowing through the optical transmission path. The monitor unit 3 monitors the operation status of the relay device 1. At a predetermined timing, the superimposing unit 2 superimposes monitor unit 3 monitoring-information onto an optical signal ofa primary signal flowing through the optical transmission path, by performing modulation processing on the basis of an oscillation signal having a predetermined oscillation frequency. The relay device1 can spontaneously superimpose the monitoring information onto an optical signal and transmit same. 提供种用于同时监视多个中继设备的技术。中继设备(1)包括叠加单元(2)和监视器单元(3)。中继设备(1)被插入在发送和接收光信号的光通信设备之间的光传输路径上，并且具有用于中继流过光传输路径的光信号的功能。监视器单元(3)监视中继设备(1)的操作状
