  • Transmission system and method for equalization of channels in the system
    Patent number: 7123834
    Abstract: The invention is related to a method for equalizing performance of traffic channels in a WDM system where means for controlling transmitters (12), amplifiers (38) and receivers (14) are provided. Potentially, a number of channels are defined as loading channels (100). The method follows the steps of measuring the optical power at the input (48) of the amplifier (38), setting the power levels of a predefined number of loading channels (100) to a high power level, setting the power level of the traffic channels (200) to a power level less then the power level of the loading channels (100), adjusting the power level of the traffic channels (200), adjusting the power level of the loading channels (100), stabilizing the sum of the optical power measured at the optical amplifier (38), continuing the process for each channel the receiver lock signal (75) is sent back to the transmitters.

  • Method for per-channnel power control in a DWDM network by means of an algorithm for adjusting the power of a dummy signal and the input power of an optical amplifier via channel-average Q-factor measurement
    Publication number: 20050152693
    Abstract: A description is given of a method for per-channel power control in a DWDM transmission network comprising at least one optical amplifier that can be gain-controlled, by injection of a dummy signal into the optical transmission network in addition to the communications signals, with the dummy signal being controllable with regard to its power, and determination of a channel-average Q-factor.
