Paper Abstract

We have analyzed the relative intensity noise (RIN) of the pump lasers transferred to the signal in a Raman amplifier system using polarization-multiplexed pump lasers. The result shows that this RIN transfer could be reduced by 3 dB using the polarization-multiplexed pump lasers instead of single pump laser. In a Raman amplifier system, the pump modulation could be used for line monitoring. We have also analyzed the power penalty caused by the modulated pump laser in such a system.
