I understand Alistu. The changes I have made in File-21 is I have replaced laser array with separate lasers and assigned frequencies as mentioned with 2nm frequency spacing and detected them by using filters as we discussed just to make sure the working of the solution. Other than that I had observed results by making changes to fiber length which was originally 20Km and how it can affect the results. I am not taking any paper as a reference at the moment. Now to get completely familiar with optisystem components and functions, I was trying to obtain a graph i.e BER against Received power.
It was earlier discussed here (http://staging.optiwave.com/forums/topic/ber-vs-received-power-curve/#post-23508) it seemed to work at that moment but again I’m getting a strange graph even when I increased the sequence length.
