The Gefen EXT-HD-CP-FM10 is a professional-grade, point-to-point HDMI extension system that utilizes fiber optic technology to transmit high-definition audio and video signals over exceptionally long distances. This specific model is configured with "pigtail" modules, meaning the fiber optic connectors (typically LC or SC) are permanently attached via a short fiber "tail" to the transmitter and receiver units, which are then housed in a protective portable case along with their power supplies. This integrated kit solution is designed for high-performance, permanent installations or semi-permanent setups in broadcast, large-scale digital signage, command and control centers, and high-end home theaters where signal integrity over hundreds of meters is critical.

The system operates by converting the electrical HDMI signal at the source into an optical signal via the transmitter unit. This light signal is then carried over a single multimode or single-mode fiber optic cable (sold separately) to the receiver unit, which converts it back to a standard HDMI output. This fiber-based method provides complete immunity to electromagnetic interference (EMI), radio-frequency interference (RFI), and ground loops, while also eliminating the signal degradation and bandwidth limitations inherent in long copper cable runs. The kit supports the full HDMI 1.3 specification, carrying deep color, HDCP, and multi-channel audio formats like Dolby TrueHD and DTS-HD Master Audio.

The inclusion of a portable hard case and dedicated power supplies makes this system a complete, deployment-ready solution for integrators. The pigtail design offers a more reliable connection than modules with removable fiber optic connectors, reducing points of failure and ensuring optimal optical alignment for the life of the installation. By providing a robust, high-fidelity, and ultra-long-distance extension path for HDMI, this system enables flawless video delivery in the most demanding and complex signal distribution environments.
