Abstract

Here is presented a method for determination of the saturation power from the EDFA (Erbium Doped Fiber Amplifier). This method uses the analytical expressions in different approximations to obtain the saturation power of the EDFA. We have obtained the saturation power of EDFA by varying the wavelength in the interval l ˛ [1.45 ‚ 1.64] mm. Also, we have calculated the absorption and emission cross-sections for optical fiber with the germano-aluminosilicate. For these values we obtain the saturation power Psat in the following interval Psat ˛ [0.1 ‚ 5] mW and the overlap-inversion factor G in the following interval G ˛ [0.1 ‚ 0.8]. Using these results we can optimize the EDFA performances and increase the capacity and distance for transmission in the optical networks..

Keywords
