Experimental 20 Gbit/s Absolute Polar Duty Cycle Division Multiplexing - Polarization Division Multiplexing (AP-DCDM-PolDM) Transmission
20 Gbit/s(2 ? 2 ? 5 Gbit/s) Absolute Polar Duty Cycle Division Multiplexing (AP-DCDM)-Polarization Division Multiplexing (PolDM) over 180 km standard single-mode fiber has been experimentally demonstrated in order to double the capacity of PolDM and increase the maximum dispersion uncompensated reach. The AP-DCDM-POLDM performance is examined utilizing a polarization stabilizer. By increasing the length from 0 km (back-to-back) to 180 km the 10 Gbit/s single AP-DCDM channels without SOP stabilizer experienced 1 dB penalty as compared to around 2 dB penalty when the SOP stabilizer is active.
