The Evertz DVI-EXTND-SC is a professional fiber optic extension system designed to transmit a high-resolution DVI (Digital Visual Interface) video signal over long distances using a single strand of fiber optic cable. Its primary function is to overcome the severe distance limitations of standard copper DVI cables, which are typically limited to about 5-10 meters before signal degradation occurs. This system consists of a transmitter unit and a receiver unit. The transmitter converts the electrical DVI signal (and often associated stereo audio) into an optical signal, which is then sent over a single-mode fiber with an SC connector. The receiver unit converts the optical signal back into an electrical DVI signal for display on a monitor, projector, or video wall processor.

Engineered for reliability in broadcast, control room, and digital signage applications, this extension system preserves the digital integrity of the source signal, ensuring pixel-perfect image quality without the electromagnetic interference, ground loop issues, or voltage drop associated with long copper runs. It supports high resolutions, including 1920x1200 and often 1080p, making it suitable for extending computer graphics workstations, presentation laptops, or data visualization sources to remote displays located hundreds of meters or even kilometers away. The use of a single fiber strand (indicated by "SC" connector type) simplifies cable management and reduces infrastructure costs compared to multi-fiber solutions.

As a critical connectivity solution, the Evertz DVI-EXTND-SC enables flexible system design in large facilities. It is commonly used in broadcast master control rooms to place operator workstations away from noisy equipment areas, in command and control centers to connect computers to large display walls, and in corporate or educational campuses to distribute high-quality video between buildings. By providing a robust, long-distance extension for DVI, it facilitates clean, reliable, and high-fidelity video distribution where standard cables cannot reach.
