Abstract
An algorithm is disclosed for performing alien-wavelength channel balancing on channels between optical network elements within an optic-fiber communications system. The algorithm determines initial values of various optimization parameters for each of the channels, such as the input launch power and operating conditions of optical amplifiers in the optical path, and calculates an initial total optimization offset for the channels based on the initial values of the optimization parameters for each of the channels. The algorithm then adjusts the optimization parameters to new values and calculates a new total optimization offset based on the new optimization parameter values. The algorithm repeats this process until the relative channel launch powers and optical amplifiers are optimized.
