Hi Dhiman,
Again this is the case I have explained earlier in your post “photodiode”, in the link below:
In case you are using 4-QAM, then you have two inputs to your QAM demodulator (or 4-QAM), whereas in the image you have attached there is only one output port to your coherent optical receiver, which enters QADM.
Regards
