Abstract :
Experimental demonstration of a dual-polarization Volterra series nonlinear equalizer applied in frequency-domain is carried out for 100G polarization-multiplexed QPSK test signals. We were able to reduce the BER by a factor of ~2.5× relatively to the single-polarization approach, with a 1 dB increase in the optimum power.
