Low-cost educational resource using optical fibers to send color images

We present a low-cost resource that aims to facilitate the teaching process of subjects related to optical fibers, given that it presents a practical application of this technology. The main purpose of this resource is to send a color image through optical fibers with a laser diode from one computer and receive it with a photoresistor on another computer, with a total estimated setup-cost of twenty dollars. The setup includes a visual user-interface, for both computers, programmed with the software LabVIEW, which lets to select and prepare an image for a proper sending and receiving. In this proposal we have used arduino boards and low-cost plastic optical fibers used in ornaments.
