Hi Faysal,
Among the Optiwave softwares, each do a separate job. So there is no other Optiwave software that can function the same as Optisystem. And since naming other products from other companies is banned according to forum rules (the way I perceived it, as it me be commercial), I cannot help further. However, Optisystem is a great software and I cannot think of systems you can’t simulate with it.
Regards
