(Configuration example of monitoring information intensive submarine equipment)
Next, in each group G1 to _Gn , a configuration example of the monitoring information intensive submarine devices 22 ₂ , 22 ₅ ,..., 22 _(n−1) located at the center of each submarine device will be described. To do.

First, the monitoring information intensive submarine equipment 22 ₂ As shown in FIG. 5, one and the other submarine optical cable 21 a reception signal converting unit a light signal transmitted through with an optical fiber (photoelectric converter) The signal receiving unit 32 that receives the signal via the signal 31 and whether or not the received signal is a status monitoring command KS for each submarine device transmitted from one base station 3 and the status monitoring command KS.

Subsequently, each of the submarine devices 22 _{1 to} 22 _n operates based on the state monitoring command KS from the base station 3 and monitors the operation state of the own device and its upstream transmission path, and monitors the monitoring result. the condition monitoring data _J 1 through J _n via the submarine optical cable outputs individually holds as data _J 1 through J _n (FIG. 6: step S602 / second step).

Then, the output state monitoring data J ₁ , J ₂ ,..., J _n are converted into the above-described one submarine equipment 22 ₂ , 22 ₅ ,. Receive via the submarine optical cable 21. Then, it is determined whether or not the received status monitoring data is status monitoring data from another submarine device in the same group, and only the status monitoring data of other devices in the same group is captured and stored (FIG. 6: Step S603 / third step).

Then, the one submarine equipment 22 _2, 22 _5, the other machine condition monitoring data in the same group incorporated into ...., of the one submarine equipment 22 _2, 22 _5, ... it is of its own state The data is aggregated together with the monitoring data and held as the aggregated monitoring data SS (FIG. 6: Step S604 / fourth process).

Then, the aggregated monitoring data SS in the aggregated same group is sent to the above-mentioned base station 3 by each of the submarine devices 22 ₂ , 22 ₅ ,. Transmit (FIG. 6: step S605 / fifth step).
