Abstract
The first experiment of polarisation-mode dispersion (PMD) impact on fibre nonlinearity in coherent optical OFDM (CO-OFDM) systems is reported. The optimal Q value at 10.7Gbit/s has been improved by 1dB after introduction of differential group delay (DGD) of 900ps. © 2007 The Institution of Engineering and Technology.
