Abstract :
We discuss the generation, transmission, and coherent detection of 14-Gbaud polarization-division multiplexed, 16-ary quadrature-amplitude-modulation (16-QAM) signals (112-Gb/s line rate). We attain 630-km and 1020-km wavelength-division-multiplexed transmission with spectral efficiencies of 6.2 b/s/Hz and 4.1 b/s/Hz, respectively.
