Pigtail module HDMI extension using a single-strand multimode fiber optic cable with HDCP support The HDMI fiber optic pigtail module extender with HDCP support extends HDMI up to 1000 feet (300 meters) using a single-strand 50/125µm multimode (OM2) 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.
