Hi Che Wan Faizul,
I also think your question is not clear enough. However, since you are new to this forum and I reckon you do not have much experience with Optisystem, I strongly suggest that you use the tutorials and videos provided by Optiwave. I tried to find a list of components available in the library in the form of a tree diagram or something and might be useful for the beginners by giving info on how components are sorted in the library, but didn’t manage.
