Optical fibers are widely used in different areas, such as industry, research, and education, just to mention a few. Due to this fact, their applications are commonly included in undergraduate engineering programs or in related fields of education. In this article, a new low‐cost educational resource for a better understanding and a practical application of optical fibers is proposed. The main purpose of this resource is to send 4‐bit images in grayscale through optical fibers with a laser diode and receive it with a photoresistor, with a total estimated setup‐cost of fifteen dollars. The setup includes a visual user‐interface programmed with the software LabVIEW, which lets to select and prepare an image for a proper sending. The same program is in charge of applying different intensities for each type of bit through a generic laser diode and of receiving the information back, all done with the aid of an Arduino Uno board, which serves as the electric interface.
