CWDM crosstalk model
Hi, I am investigating crosstalk in CWDM systems. Initially I am building a basic model so I can understand how the different components work. I have built a 2 channel CWDM model with the laser from one of the channels fixed at 1490nm and the second laser is nominally at 1470nm but it is being swept from 1420nm to 1540nm. I have had a result I cannot explain. I have carried out the simulation in EXCEL and they do not agree.
I have attached the optisystem simulation and the result I am querying.
In the picture “layout”. The top left laser is being varied by wavelength. I am interested in the effect it has on the other laser (bottom left) and its receiver optical power meter_2.
In the picture “result” the large curve is as I expected. It is the spike to the right that has me puzzled. Any help would be most appreciated.
