Submarine optical cable system, monitoring information intensive submarine equipment, system monitoring method, and program for monitoring the same

摘要

PROBLEM TO BE SOLVED: To provide a submarine cable system that can shorten an overall state monitoring time while maintaining accuracy in state monitoring of each submarine device.SOLUTION: Submarine devices 22-22are divided into multiple groups G1, G2, etc. in a range of 2 to n/2, and at least one submarine device included in each group G1, G2, etc. is configured by a monitoring information aggregation type submarine device that has a function to capture and aggregate, as state monitoring data, the operation state of each of other submarine devices in the same group. Each monitoring information aggregation type submarine device has a monitoring information transmission function 22G transmitting the state monitoring data related to the operation state of each of the submarine devices as collected aggregation monitoring data SS to a base station 3.
