Method for per-channnel power control in a DWDM network by means of an algorithm for adjusting the power of a dummy signal and the input power of an optical amplifier via channel-average Q-factor measurement

摘要

A description is given of a method for per-channel power control in a DWDM transmission network comprising at least one optical amplifier that can be gain-controlled, by injection of a dummy signal into the optical transmission network in addition to the communications signals, with the dummy signal being controllable with regard to its power, and determination of a channel-average Q-factor.
