      When using ofdm modulated qam optical communication and using optisystem for simulation, why do you change the laser light source into the LED with the same frequency? The constellation diagram is originally four scattered points

      Hello,
      Which version of OptiSystem are you using?
      The choice of the LED or LD wavelength/frequency is the user choice.
      I assume you are referring to the constellation at the input side, which is four points. This is the input constellation, you need to check the constellation at the receiver for the system performance.
      Regards,
