50 Gb/s Dual Polarization 32QAM-MultiCAP Downstream Transmission using 10G Heterodyne reception with DSP based PolDemux

We present a 50Gb/s downstream PON link based on a PolMux 32QAM-MultiCAP modulation and a heterodyne choherent receiver with DSP based PolDemux. 25km transmission is achieved using 10G electronic and photonic devices with a sensitivity of -25dBm for the worst band and polarization.
