The Gefen FM10 HDMI Fiber Optic Extender with HDCP support extends HDMI up to 3300 feet (1000 meters) using single-strand 50/125 um multimode (OM2/OM3) SC-terminated fiber optic cable. Optical signal transmission provides galvanic isolation and immunity to electromagnetic interference compared to similar copper based extension modules. The pigtail design of the Sender and Receiver modules relieves stress and clutter on the source and display connector panels. Their compact design makes them ideal for fitting neatly behind equipment for a clean installation, making it a great way to easily extend HDMI.
