Help with parameters in FSO-PON Architecture

[Ayush Kumar]

I am working on a hybrid FSO-PON architecture in optisystem , I am getting high error and only 4 data points in constellation diagram. How do I solve these problems.
parameters are set as
4BBUs:
PRBS-10Gbps
QAM -4QAM
OFDM-512 subcarriers,8 prefix points , 256 subcarriers per port and power 10dBm
Qyadrature modulator – default parameters
Modulation is done using source from a frequency comb generator (193.414-193.489Thz) 25GHz spacing
WDM bandwidth 10Ghz
SMF-15Km
FSO -default
Reciever:
after FSO there are photodetectors (PIN)
the quadrature demodulator
OFDM demodulation block
QAM sequence decoder
NRZ
BER analyser
so how do I set the parameters to get proper results please assist
