WDM BER measurement
I am validating a model to investigate crosstalk in a CWDM system. I have attached the simulation and a graph of how the change in wavelength of CW Laser affects the min Log BER from the BER analyzer.
The laser and the BER analyser are from the same channel so I would expect the BER to be more or less constant at around 1×10^100 as the link is short. Hence the Log of the BER would be about -100. Every time I run the simulation the first sweep always gives a Log BER in the order of -10 with subsequent sweeps giving a Log BER around -100. I have varied the starting wavelength and the number of sweeps and I keep getting similar results. For some reason the first sweep is not working.
