Title :
Polarization QAM modulation (POL-QAM) for coherent detection schemes
Author_Institution :
Alcatel-Lucent. Bell Labs., Stuttgart
Abstract :
A new polarization constellation diagram leads to polarization QAM modulation formats. At 28 Gband (112 Gb/s) POL-QAM 6-4 with six QPSK modulated states-of-polarization enables 1.7-dB higher sensitivity than PDM-QPSK by applying coded-modulation with an inner RS(511,455) FEC.
