After SMF Output Figure 83 -The results of the scripted calculations of a dispersion compensated link span Chances are that this single link might be useful for building longer multi-span systems. In that case it is recommended to encapsulate it into a sub-system, which would later on allow reproducing the same combination of components quickly and efficiently. We create a new design version, selecting “Design Version/ Add Design Version” from the main menu of OptiSys and change its name to “Amplified Dispersion Compensating Subsystem”. After that we copy and paste all the components of Version 1 in it. Next, as shown in Lesson 2: Subsystems – Hierarchical simulation, we select all the components, except the signal source and the booster amplifier (including or skipping the visualizers), and select “Create subsystem” from the right click context menu. Our layout collapses into the visual representation of a subsystem. First we create an output port in the subsystem by selecting “Look Inside” from the right-click menu and using the “Output port” tool. After that we can change the name of the new subsystem to something informative, for instance “Amplified Dispersion Compensated Span”, using the “Component Parameters” menu item. 62
Figure 84 -The dispersion compensated span represented as a subsystem Next we can use the newly created subsystem to build longer multi-span links. Let us create another design version and change its name to “Multi-Span Link”. After that, we copy and paste all the components of “Amplified Dispersion Compensating Subsystem” in it. Now we can arrange a three span system by copying and pasting the “Amplified Dispersion Compensated Span” subsystem component and linking the respective input and output ports.
