Abstract
Official abstract text for this publication.
An optical transmission system includes a first node and a second node, the first node includes a first optical amplifier which outputs a signal to the second node through a first transmission line and a first monitoring unit, the second node includes a monitor which monitors a signal from the first transmission line, a second optical amplifier which outputs a signal to the first node through a second transmission line and a second monitoring unit, upon detecting disconnection from the first transmission line, the second monitoring unit transmits a notification for making power of the first optical amplifier reduced, upon receipt of the notification, the first monitoring unit reduces power of the first optical amplifier, and transmits a completion notification to the second monitoring unit, and upon not receiving the completion notification even after expiration of an allowed time, the second monitoring unit reduces power of the second optical amplifier.
First claim
Opening claim text (preview).
The invention claimed is: 1. An optical fiber transmission system comprising a first node and a second node neighboring with each other, wherein said first node comprises a first optical amplifier which outputs a signal to a first transmission line for transmitting a signal from said first node to said second node, and a first monitoring control unit, wherein said second node comprises a monitor which monitors arrival of a signal from said first transmission line, a second optic…
