| 摘要 |
<p>The invention relates to a method for feeding an optical sum signal (3) comprising an optical auxiliary signal (2) and an optical payload signal (1), in particular a burst-mode payload signal, to an optical amplifier, wherein the power of the auxiliary signal (2) is controlled such that an essentially constant power of the envelope of the sum signal (3) is generated, and wherein a nominal value (18) of the constant power of the envelope of the sum signal (3) is controlled in dependence of a measured or expected property of the payload signal (1), in particular a maximum possible power (P max ) of the payload signal (1). The invention further relates to an optical amplifier device, to a tree-shaped optical network comprising such an optical amplifier device, and to a central station for such an optical network.</p> |
