In order to calculate the system performance based on the number of Fibers and EDFA spans you can use the Loop Control. The Loop control allows you to set the number of times the signal will propagate in the components connected between the Loop Input and Loop Output ports. • From the component library, go to Default > Tools • Select Loop Control 1.0 and place it onto the workspace by dragging the icon from the library. • Connect the EDFA Ideal (the one connected to the Multiplexer) to the Loop Control input, • Connect the Loop output port to the Nonlinear Fiber input, • Connect the EDFA Ideal (the one connected to the Fiber) to the Loop input port. Figure 51 -Loop control The parameter Number of loops in the Loop control defines the number of round trips for the signal in loop. • In the Loop control properties, set the value of the Number of loops to 3. 36
Figure 52 -Loop control parameters This means we will propagate the signal in 3x80km = 240 km. • From the component library, go to Default > WDM Multiplexers Library > Demultiplexers • Select WDM Demux 1x8 1.0 and place it onto the workspace by dragging the icon from the library. • Connect the Loop control output to the WDM Demux 1x8 input. You can also display the channel frequency values in the layout. Figure 53 –Demultiplexer 37
