      The optisystem provides a tutorial file, with the control loop that includes the optical fiber and an amplifier, how do I plot the graph of BER vs OSNR for each channel demultiplexer eight ports?

      Hi Heitor, I’m not sure if I understand your question correctly. Do you want to plot the graphs using just 1 analyzer?

      Here in the tutorial of optisystem was used a demultiplexer for 8 ports, then as will increasing the amount of laps, the value of the BER and OSNR changes, what I want to know how to plot graphs of BER vs. OSNR, for a two eight ports of the demultiplexer

      The relation between BER and OSNR is

      Log10 (BER) = 10.7-1.45 (OSNR)

      And how would plot BER vs. OSNR in optisystem?

        The WDM Analyzer has a result which is actually the OSNR of each channel, so you could use that as your dependent variable. Add another one at the output of the loop and then plot the parameter sweep.

        Cheers
