Abstract :
We have investigated through simulation study the transmission performance of PM-16 QAM based Nyquist-WDM transmission system over 10×80 km using a combination of mid-span spectral inversion (OPC) and distributed Raman amplifier (DRA). In this study, we have focused on the deployment of spectral inversion technique (OPC) and optimum Raman amplifier configuration towards improvement of system performance. Comparison is also done, where no OPC is used. Our analysis shows that, introduction of DRA with optimized pumping scheme significantly reduce fiber non-linearity, which improves of the system performance compared to the situation where only spectral inversion technique is used.
