Abstract :
In distributed optical fiber Raman amplifiers, instantaneous pump power depletion is related to the patterns of the input wavelength-division-multiplexing signals, especially for high bit rate application. This results in additional optical noise and interchannel crosstalk. We analyzed the phenomenon and presented simulation results. The cases for different bit rates and channel numbers were compared.
