Abstract :
We propose a passive optical network (PON) system based on quadrature amplitude modulated (QAM) sub-carrier multiplexing (SCM) of 53 6 MHz 64/256-QAM channels. Sensitivities of -22 dBm and -17.5 dBm are achieved over 51 km of fiber under full duplex and broadcast delivery to 128 nodes for 64 and 256 QAM, respectively.
