Figure 48 -Entering frequency values Testing the transmitter In order to verify the system setting for this design we will use an OSA and a WDM analyzer to obtain the signal spectrum and the total power for each channel. • From the component library, go to Default > Visualizers > Optical • Select Optical Spectrum Analyzer 1.0 and place it onto the workspace by dragging the icon from the library. • Select WDM Analyzer 1.0 and place it onto the workspace by dragging the icon from the library. • Connect these visualizers to the Ideal EDFA output • Run the simulation. • Double-click in the visualizers to display the results and graphs. You should obtain the signal spectrum showing 8 channels equally spaced, the WDM Analyzer will also show the 8 channels, the average signal power for each channels is around 17 dBm for a resolution bandwidth of 0.1 nm. 34
Figure 49 -Simulation results from the visualizers EDFA + Fiber spans To create a fiber connected to an EDFA follow these steps: • From the component library, go to Default > Optical Fibers Library • Select Nonlinear Dispersive Fiber 1.0 and place it onto the workspace by dragging the icon from the library. • In the Nonlinear Dispersive Fiber properties, change the parameter Length to 80 km. • From the component library, go to Default > Amplifiers Library > Optical > EDFA • Select EDFA Ideal 1.0 and place it onto the workspace by dragging the icon from the library. • Connect the Nonlinear Dispersive fiber output to the EDFA Ideal input.
