Abstract :
In order to push the nonlinear Shannon limit further within practical implementation constraints, we discuss various nonlinear compensation techniques for intra- and inter-subcarrier nonlinear effects. Experimental and numerical results prove the benefit is not just pre-FEC BER improvement.
