Popis:	Nonlinear optics is hardly considered on beam propagation in EDFAs. Hereby, we will study the effects of SRS on the distributed EDFAs pumped by 1480 nm wavelength. The results of numerical simulation show that the SRS in DEDFAs cannot be neglected due to its serious affects on noise and the spectral gain of amplifier. The numerical results will be demonstrated and the possibility of using SRS for gain broadening of the EDFAs will be described.© (2002) COPYRIGHT SPIE--The International Society for Optical Engineering.
