Abstract :
We evaluate by simulation the maximum reachable distance of ten Nyquist-WDM channels at 240 Gbps based on PM-16QAM in PSCF links. Operating with a channel spacing of only 1.1·RS and using Raman amplification, we demonstrate a maximum reachable distance of 3,600 km. Moreover, we make an assessment of the scaling of nonlinear impairments in the case of using hybrid EDFA/Raman amplification.
