OPTIC PANEL Q & A
Why can you see the color red out of a 850nm Mulitmode Fiber Cable or Panel?
The visible light spectrum is 380-750nm and a Multimode Fiber optic runs at 850nm. If you are in a dark area you will be able to see the color red coming out of the cable or panel. (I am not looking directly into the source or cable end). Why are you able to see any color since it should be operating out of the Visible Spectrum?
Red has wavelengths between 630nm and 740nm. The information is sent at the speed of light but propagrates through the transparent medium (fibre) resulting in the light radiation slowing down to approxiamately 200,000km/s causing the wavelengths to become shorter there for the waves emit to the eye as red.
