Process for controlling the output power of an optical amplifier at a node in a network, node in a network and network comprising at least two nodes

摘要

"PROCESS TO CONTROL THE OUTPUT POWER OF AN OPTICAL AMPLIFIER IN A NODE IN A NETWORK, NODE IN A NETWORK AND NETWORK UNDERSTANDING AT LEAST TWO Nodes". The present invention relates to a process for controlling the output power of an optical amplifier (14, 15) on a node (N1, N2, N3, N4, N5, N6) in a network, where the output power of the amplifier (14, 15) is controlled via a pump laser (32) in a control circuit. According to the invention the node (N1, N2, N3, N4, N5, N6) reads a supervision channel (OSC), comprising information on how to control the amplifier (14, 15). The node (N1, N2, N3, N4, N5, N6) then uses said information to control the amplifier (14, 15).
