The invention concerns a method of determining the spectral characteristics of a optical amplifiers. Two methods are proposed for determining the spectral gain and the ASE spectral power density of an amplifier. Each method uses two spectral functions T( , ref), R( , ref) and TASE ( , ref), RASE ( , ref), respectively. The spectral functions are determined by calculation using two measured spectra of gain and ASE output power density, respectively, made at two different saturation states of an amplifier. The functions are independent of the operating conditions of the amplifier. This allows deviations in the calculated functions to be immediately identified and further enables the optimal area of application of the model to be located.
