Abstract :
We assess adaptive modulation techniques for bandwidth-elastic, continuously spaced CO-OFDM systems. An iterative loading algorithm employing an FWM-based nonlinear interference model is proposed. Increased tolerance to fiber nonlinearities compared to conventional loading schemes and significant improvements over non-loaded schemes are obtained.
