Abstract :
A crosstalk effect in counter-pumped distributed Raman amplifiers (DRAs) with discrete time-division multiplexed (DTDM) pumping is investigated using numerical modeling. We show that the pump repetition frequency has an impact on the pump mediated cross modulation between two channels. Crosstalk effects between channels are shown to be worse in the case of DTDM pumping in comparison with continuous wave (CW) pumping at lower pump repetition frequencies
