When digital ain't good enough to transfer your AV, you might as well get all wonky and tranfer it using pure light. Once the digital signal is translated by a fiber optic converter, it's immune to signal noise. That means they can run up to 100 meters, without a problem. One problem, however, is the price. With swappable HDMI/DVI ends, the cable runs $550 for a 10 meter batch. Brothers and sisters, you don't want to know how much the 100 meter cable is.
