Can u please solve the problem of Bit error rate.i am designing gain flatness in Edfa_Wdm system and i tried so many papers on that topic to get good result but in every paper i got very big value of bit error rate. i want to know how can we improve bit error rate and what factors it depends. i attached my file

Hi,

There was a small problem with your WDM 1×2 component. I believe you were trying to determine the BER of a single frequency channel. If that’s the case then you need to make sure the channels of your demux match up with the channels that are being transmitted. Attached is a quick fix I made to your project file. Just look at the properties of the WDM 1×2 component to see the changes I made.

thanks a lot for helping but the project file u have attached is not opening.may be because i have optisystem 7.i can try to open this project file on optisystem 12.

[anita sharmaParticipant]

can u please tell me in which version u have edited above project file because your edited project file is not opening in optisystem 7 and optisystem 12.

Sorry about that! The project was saved in OptiSystem 12.2. If you can’t open it you can try fixing it yourself. I just changed the channel frequencies in the Demux component. They should be changed to 193.11149 THz and 193.81412 THz.
