Abstract

A transmitter with 4 digital-analog converters enabled the generation of 4-D optimized constellation with 6 polarization states (POLQAM) at 28-Gbd. A new feedback signal ensured adaptation of the CMA polarization demultiplexer in the off-line receiver and allowed comparison with polarization-switched QPSK (PS-QPSK) and DP-QPSK.
