Experimental research on gain characteristics and nonlinear effect of dispersion compensation Raman amplifiers
分立式色散补偿拉曼放大器增益特性及非线性现象研究

Discrete dispersion compensation Raman amplifiers (DCRA) are recently used in dense wavelength division multiplexing (DWDM) systems for compensating for both dispersion and fiber loss simultaneously. In this paper,the gain spectrum,gain saturation and the effect of stimulated Brillouin scattering (SBS) of DCRA have been experimentally investigated.
