Abstract
In order to study the key technology of distributed fiber Raman amplifier,combining the numerical simulation and the experiment,the power coupling equation group was analyzed in theory,and the reciprocity of the pumps and signal was calculated,then the number of pump source,wavelength and power satisfying the gain were obtained.The on-off gain of signals in C+L band up to 10dB,gain flatness less than 1.6dB,gain of polarization relativity less than 0.4dB,polarization mode dispersion less than 0.16ps were obtained by adjusting the pump power.The experiment results indicate that the pumps parameters fully satisfy Raman gain of the system,the technique parameters of the system meet communication standard.
