Experimental demonstration of joint SPM compensation in 44-Gb/s PDM-OFDM transmission with 16-QAM subcarrier modulation

We report the experimental demonstration of a recently proposed joint self-phase modulation compensation scheme in a single-channel 44-Gb/s polarization-division multiplexed OFDM transmission with 16-QAM subcarrier modulation, achieving power tolerance improvement as large as 5 dB.
