Abstract

The present invention relates to a method for optimizing performance of a multi-span optical fiber network, wherein each span has an associated optical transmission fiber connected to an associated optical amplifier, wherein gain and output power of the associated optical amplifier are respectively controlled independently, and wherein an amplifier noise figure respectively depends on the gain of the associated optical amplifier wherein each associated optical amplifier is further connected to launch optical signals into a remainder of a corresponding optical transmission line, and wherein the method (20) comprises the steps of:- for each span, computing the amplifier noise figure and a non-linear noise generated in the span based on information about the span (21) and using the computed amplifier noise figure and the computed non-linear noise to compute an optimum launch power (22);- optimizing performance of the multi-span optical fiber network based on the computed optimum launch powers of all spans (23,24).
