Automatic control of parameters of optical components such as colored losers in a transmit side WDM system includes the following steps. At a receiver side (NE21-NE2n)) predefined characteristics of a received signal are measured. The results (MEAS) of these measurements are communicated to a remote control system (NMS1) which runs an algorithm to determine corrective adjustment parameters (ADJ) and communicates them to the transmitter side (NE11-NE1n), which adjusts the optical components accordingly. The adjustment algorithm is implemented in one of the affected network elements or in the related network management system, preferably in the element manager (NMS1) of the affected network elements. The measurements are provided automatically to the algorithm; the related adjustments are provided automatically to the network elements, which contain the transmitters to be adjusted.
