Pigtail module DVI extension using a single-strand multimode fiber optic cable with HDCP support. The Gefen DVI fiber optic pigtail module extender with HDCP support extends DVI up to 3300 feet (1000 meters) using single-strand 50/125 µm 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 DVI.
