Hello Ranadheer,
May I ask which version of OptiSystem are you using currently?
You should be able to find the Dual Port WDM Analyzer in the component library at location: Default\Visualizer Library\Optical\Compare. You must find this component here.
One quick way to search any component in the library is by right clicking on the Component library section and searching for the particular component.
Let me know the version of OptiSystem if you still did not find the component. Also, please reply at support@optiwave.com.
Best,
Saurabh Bedi.
