Fiber optic HDMI cables are a new product that has very good performance in terms of video quality, and they can be hundreds of meters long without any attenuation or distortion.
The fact that these cables are made entirely of optical fiber make us think that they have zero electromagnetic emissions, but this is true only for the cable, the small terminals at both ends of the cable emit quite a lot of electromagnetic radiation.
The type of electromagnetic radiation emitted by the terminals of a typical optical HDMI cable are akin to that of older cell phones. The effects go from skin burning sensation, to severe head ache, tinnitus and pain in the ears.
