Hello Sayed

Your system is working well,the only thing you need to add is power booster after the WDM Tx(Prior to SMF).In your system Fiber length after the mux is 100km followed by EDFA,it is better to consider pre amplifier so that in every loop signal will be amplified and mitigate the effects of attenuation efficiently.FBG you have used is working well too.I have add pre amp to your system and system works for 10(1000Km) loops and may it go further.I have attached the file below.Tell me if this works for you and feel free to ask if you have any doubts regarding this setup.

Regards

If you mean “how to find Q factor/BER” in your file, you simply have to right-click on the BER Analyzer component, and under “component results” you find what you need. Does this answer your questions?

PS: for next topic, could you be more specific in the topic name? this will ensure that more people will answer to your questions 🙂

I think find my question ans clearly.Thanks everyone.

Alessandro Sayed had some problem in signal amplification thats why he couldnt get q-factor at receiver side.Welcome sayed aman ullah,best of luck for research. If you will have any problem share with us

Thanks Abhishek, I ran the simulation file and I did get Q/BER, this is why I did not fully understand the question…

Regards!
