The fiber optics kit tend to demonstrate to the trainee different design of the optic fiber systems, and the method of changing the current electrical system to fiber optics.
- simplex cable
- The simplex cable with PMMA fiber finds application for short distance analog and digital signal transmission. The step index fiber has a large area of cross section and a high numerical aperture facilitating easy coupling with transmitting and receiving devices. The light is guided along a fiber of one millimeter approximately to distances of a few tens of meters. The other main applications of PMMA fiber are in sensors light guides and displays.
