Achmad has designed a fiber optic simulation software which is freely avaible for download. Here is the software’s description:
Fiber Optic Simulation Application is a simulation application that simulate meridional and skew rays inside fiber optic cable.This application can simulate step or graded index fiber. It also can simulate single or multimode for meridional ray.For skew ray, there’s only single mode.
