Hi to everyone... I had a silly question to ask... I know that the light in a fiber travels faster than a electromagnetic signal in a wire. I was wondering how photodetectors work because we all know that they convert the ligh to electromagnetic signals. But if the light travels faster than the e/m signal in a wire then i think that inside the photodetector some sort of information will be lost because we can't produce electricity that runs faster than the light..
