Time Division Multiplexing (TDM)

Hello
I am combining the electrical signals and I use the result of this combination to modulate a single AM modulator, where the optical carrier enters. However, my eye chart is duplicated due to the sum of the signal over time, which is done using the combiner. I am attaching the transmitter and receiver images as well as the eye diagrams obtained in the simulation.
Does anyone have any suggestions for this problem?
Thanks

      Hi Sinara,
      Would you be able to attach the project as a Zip file so i can have a look at it.
      There is also an example on an OTDM multiplexer that you may find helpful located at

      Regards,

      Hello

      I am sending the simulation file for you to check.
