Hello everyone, I apologize for the simplicity of these questions. I would like to understand the significance of the color grades (yellow,orange,red pink, blue etc.) displayed in the BER analyzer. For example, in the attached picture, I have the results of two WDM systems, both simulated at a power level of -15 dBm with RZ modulation. However, one system includes Radio over Fiber (RoF) while the other does not. I noticed that the color grades are more prominent in the RoF system. I would appreciate any clarification on this matter. Thank you!
