Checking Opto-Fibers with a Smartphone

Todays discovery is simple, but nevertheless practical. Do you need the check optical fibers (e.g. from SFPs or AVAGOs) from time to time? It's sometimes hard to see if they are on, plus you probably do not want to direct a small laser right into your eye.
The solution is to use the camera of a smartphone, webcam, etc. This approach is especially useful, if the frequency is infrared or close to it, because the CMOS sensor is more sensitive in this frequency range.
