Hello Sahil Singh. Greetings.
Thanks for replying but i don’t find the reply given by ranjeet very relevant. He is explaining something very different which i think is simply some explanation of some already designed module. Here i am asking a simple question about the added wavelength. It has nothing to do with multiplexers, demultiplexers , filters and their responses. I hope you try to understand my query and reply accordingly. Thanks for your anticipations anyway.
Regards
Atul Sharma
