how to do a simulation of a system working with 160 Gbit/s for 500 Km
Noise factor Q > 7
BER 10^-9
with loop
Thank you.

      Hello,
      As far as loops are concerned there are few links i am posting that might help u. Generally The Loop Control allows you to set the number of times the signal propagates in the components that are connected between the Loop Control input and output ports. Use the Loop Control to calculate the system performance based on the number of fibers.
      To connect the Loop Control, perform the following procedure.
      From the Component Library, select Default > Tools Library.
      Drag the Loop Control to the Main layout.
      Connect the output port of the WDM Mux 8×1 to the first Loop Control input port.
      Connect the first Loop Control output port to the Optical Fiber input port.
      Connect the output port of the second EDFA Ideal (connected to the Optical Fiber) to the Loop Control input port.

      Here is the complete link

      Hi Mahmoud Ghorbel,
      You can use wdm system of 8 channel with global rate of 20 gbps using different advanced modulation formats like CSRZ, DRZ, MDRZ or DPSK.
      You should use dispersion compensation techniques like pre, post and symmetrical.
      You could change fiber length by using no. of loops.

      here i am uploading a osd file of csrz wdm system

      Hello Mahmoud Ghorbel,

      As Hamza ali has already given you an idea how to deal with loop control parameter. Still for your convenience i will try to repeat it that you need to first drag the Loop Control to the Main layout, Connect the output port of the WDM Mux 8×1 to the first Loop Control input port, Connect the first Loop Control output port to the Optical Fiber input port, Connect the output port of the second EDFA Ideal (connected to the Optical Fiber) to the Loop Control input port.
      You may refer to these links for further study. I hope this will help.
