Mathematical model of amplified stimulated raman scattering and fiber raman amplifier

Abstract EN

The result of a developed mathematical model for predicting the design parameters of the fiber Raman amplifier (FRA) are demonstrated.

The amplification parameters are tested at different pump power with different fiber length.

Recently, the FRA employed in optical communication system to increase the repeater distance as will as the capacity of the communication systems.

The output results show, that high Raman gain can be achieved by high pumping power, long effective area that need to be small for high Raman gain.

High-stimulated Raman gain coefficient is recommended for high Raman amplifier gain, the low attenuation of the pump and the transmitted signal in the fiber lead to high Raman gain.
