Experimental Investigation of an Optically-superimposed AMCC in 100 Gb/s Coherent WDM-PON for 5G Mobile Fronthaul

We proposed and demonstrated experimentally a 100 Gb/s coherent WDM-PON for 5G mobile fronthaul controlled by an AMCC superimposed on the optical signal. The -26 dBm receiver sensitivity required for both the AMCC and DP-QPSK signals was achieved when the modulation index was set to between 5% and 40%.
