Abstract
We present a dual-stage equalization method for long-haul coherent polarization-multiplexed systems. Blind CD compensation and adaptive multi-modulus equalization are both implemented in frequency-domain to allow zero overhead transmission with least complexity. Experiment is conducted to show good performance for both QPSK and 16-QAM systems. © 2012 Optical Society of America.
