Abstract :
We derive analytic formulas for SNR improvement by a digital nonlinear compensator for uncompensated links by using a four-wave mixing approach. The improvement only depends on fiber parameters as well as on total and received bandwidth. We discuss dependency of the improvement on fiber type and validate the analysis by numerical simulations.
