50-Gb/s PDM-DMT-SSB transmission over 40km SSMF using a single photodetector in C-band

We experimentally demonstrated transmission of 50-Gb/s PDM-DMT-SSB signal over 40km SSMF in C-band using a single photodetector. The DMT signal in another polarization is placed at the guard band of the SSB-OFDM signal.
