      Usually there is no line in the middle like this but might be your system close it with this line!!
      improve the system by for example remove the fiber make it back2back and check the eye diagram again !!

      ok.Match your input mapped data (baseband signal)and output signal (in case after LPF) using dual port oscilloscope.If there is any delay or DC shift in output baseband signal,try to remove it and hopefully this middle line would be removed.

      Dear Mohammed AAA and Muhammad Saqlain

      Thanks for your reply and interest

      Actually the issue( horizontal line in eye) was resolved by changing the TIME WINDOW value of eye analyzer from 1.5(Default) to 1 or 2 or 3.For you information please
      regards
