Abstract :
We experimentally generate 28-GBd 6PolSK-QPSK signals by utilizing a high-speed 4-channel DAC and an integrated dual-polarization I/Q modulator. In WDM transmission experiments over up to 4800 km standard single-mode fiber, we compare the performance of 126-Gb/s 6PolSK-QPSK and 112-Gb/s PDM-QPSK signals.
