ABSTRACT:
In a method for determining a power of an amplified spontaneous emission in an optical fiber amplifier for a WDM signal, wherein the optical fiber amplifier includes at least a first amplifier stage having a predetermined output power set for a measured input power, a first mean inversion is determined for the first amplifier stage. A first output power of the amplified spontaneous emission is determined at an output of the first amplifier stage by reference to tabulated values which depend on the first mean inversion.
