  Dear Members
  I am simulating my system without any amplifier and the results are good with low BER and Q factor=15
  
  I want to inquire:
  
  1-Can i simulate the system without Optical Amplifier or EDFA with Fiber Length =50km
  
  2-On which Fiber Length it becomes necessary to use amplifier?
  Plz find system picture in attachement

  Yes you can! The requirement of implementing an amplifier depends on, your Laser power, the loss in the fiber and the receiver sensitivity (basically thermal noise level).
  
  You can then base this requirement on a desired BER or Q factor of your receiver.
