摘要：The present invention relates to a method and a device for the adaptiveconfiguration of a transmission signal in a coherent WDM-PON having an optical linetermination and several end nodes. The method comprises the following steps: a)producing the transmission signal by means of at least lasers, which are each associatedwith a respective optical transmission spectrum having associated spectral ranges,wherein a spectral range of the transmission signal is suitable for transmitting data in thecoherent WDM-PON to an associated active end node of active end nodes, wherein arespective active end node of the active end nodes is associated with a spectral range ofthe lasers and wherein ≤ ⋅, = {1,2,3,4,...}, and = {1,2,3,4,...}; b) monitoring the number ofactive end nodes; c) reassigning each active end node associated with a spectral range ofa laser to be switched off to a respective free spectral range of the remaining lasers ifthe number of active end nodes is reduced to ≤ (1) - p; d) announcing the new assignmentof the spectral ranges; and e) switching off the laser to be switched off.
