Need some help understanding how to configure the parameters to yield a suitable Q-factor/eyediagram for global layout parameter Bit Rate = 10e+009 bits/s. I can generate Q=~5 @ 10e-009 using the examples in OptiSystem folder. How can this be improved?
Thanks in advance for your help.

      Hi, In order to improve system performance it is necessary to know what components have been used and what values have been assigned to these components. Also, a knowledge of the modulation schemes and the channel is crucial. So I suggest you upload your implementation if it is possible.

      Regards

      Hi alistu,

      Attached is an updated file. I am trying to configure for Q-factor = ~7 for 100m MM fiber with 3.5db/km at 2000Mhz.km, with lowest power.

      Thank you for any insight and help.
