NARRATIVE
         Fiber Optics is similar to the light pipe in that the fibers bend light by total internal reflection. Before turning on the light source, turn the knob counterclockwise. Adjust the intensity after switching on the source. Remove the caps on the fiber and hold one end on the output of the light source.
