<p>In a network management system for an optical network, wherein the optical network comprises at least one optical fiber line (1) for transmitting an optical signal having a plurality of optical amplifiers (2) and the network management system comprises a central management unit (5) for controlling the optical amplifiers (2), the management unit (5) periodically determines the output power (P out ) of each optical amplifier (2) taking into account noise power and signal power of the optical signal, and subsequently sets the output power (P out ) of each optical amplifier (2) to a target output power so that at least the signal power at an output end (7) of the fiber line (2) is set to a predetermined value.</p> |
