【発明の名称】光中継器の監視制御方式
Document Type and Number:
Japanese Patent JP3320452
Kind Code:
B2
Abstract:
Each optical repeater in an optical transmission system includes an optical amplifier, and a control circuit for controlling the optical transmission. Furthermore, each optical repeater transmits management information to the next optical repeater. The control circuit checks the status of the optical amplifier and obtains monitoring information. The control circuit generates management information in accordance with the monitoring information and the management information transmitted from the upstream side optical repeater. The management information is converted to an optical signal and transmitted to the next optical repeater. A receiving station receives the management information. The management information includes an ID code for an optical repeater which has failed and the status of the failure. Different categories of management information have priorities which can be changed by the receiving station, and thus the receiving station can detect the status of the optical transmission line easily and flexibly.
