      Hello, I have a rof integrated with dwdm-pon system, after the LPF it gives the result of the BER analyzer like this.

      My system is basically like this :

      prbs and nrz is connected with sine generator by electrical multiplier, then it is modulated with cw laser to go through mux, then a 70 km optical fiber, demux, bessel optical filter, optical amplifier, splitter, APD, then LPF.

      Some helps are appreciated.
      Thanks..

      Hi,

      You better to use MZM instead “sine generator and Electrical multiplier”. Because you are using DWDM PON, i hope it will work.
