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 fibers are in sensors light guides and displays.
