Abstract:
1. A method for optimizing the gain of a parametric amplifier for a WDM signal, the method comprising: a) fixing a pump wavelength of said amplifier at a first wavelength according to a zero dispersion of an optical fiber; b) increasing a pump power of said amplifier at said first wavelength so that measured channel powers of a wavelength grid reach a first level P0; c) tuning a wavelength of a pump source so as to reduce an excursion of the measured channel powers of the wavelength grid and maintain a minimum power of the channels of the grid at P1, where P1<P0; d) increasing or decreasing the pump power so that the measured channel powers of the wavelength grid reach the first level P0; and e) running the procedure steps c) to d) to obtain the first level P0 in the channels and obtain the minimum excursion in the channels.
