Fiber optic networks and testers generally use infrared light in the 850-1600 nm range, invisible to the human eye. But high power in fiber optic systems can be harmful to your eyes, so it's important to know if power is present in a fiber. A fiber optic power meter can be used, but you may not always have one on hand. The camera in old cell phones - those before smart phones - is sensitive to infrared light - lots more than your eye - and can detect light in an optical fiber or from a transmitter. Dig into your junk drawers and find that decade-old flip-phone and try it on a fiber optic transmitter. Here's how to do it.
