OPTICAL AMPLIFIER CONTROL

摘要

The present invention relates to a method for controlling the output power of an optical amplifier (14, 15) in a node (N1, N2, N3, N4, N5, N6) in a network, wherein 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 supervisory channel (OSC), comprising information on how to control the amplifier (14, 15). The node (N1, N2, N3, N4, N5, N6) then uses said information for the control of the amplifier (14, 15).
