The Gefen EXT-HD-1000, which corresponds to the EXT-HD-CPNT-FM10 model range, is a high-performance extender system designed to transmit HDMI signals over a single strand of multi-mode fiber optic cable. This solution is specifically engineered to overcome the distance limitations of standard copper HDMI cables, enabling signal transmission over significant distances, typically up to 1,000 feet (300 meters). The system consists of two main parts: a Sender unit and a Receiver unit, which are connected via a user-supplied fiber optic cable. This technology ensures the integrity of the digital signal is maintained over the long haul, free from electromagnetic interference (EMI) often present in complex installation environments.

The extender supports high-definition video resolutions up to 1080p Full HD (1920 x 1080) and PC resolutions up to 1920 x 1200. It is fully compliant with HDCP (High-bandwidth Digital Content Protection) standards, ensuring compatibility with protected content from sources like Blu-ray players or set-top boxes. The system also passes high-quality digital audio signals, including 7.1 channel LPCM, Dolby TrueHD, and DTS-HD Master Audio, making it suitable for professional AV systems where both premium video and audio quality are required.

Designed for professional reliability and ease of installation, the Gefen extender is a compact, plug-and-play solution that typically requires no additional configuration or drivers. Power is usually supplied via external DC power supplies connected to both the sender and receiver units. The fiber optic connectivity is the primary benefit, offering a lightweight and flexible cabling solution compared to heavy copper alternatives, ideal for in-wall or long-distance conduit installations in commercial or residential settings.
