The JVC Professional FS-790SNG is a professional-grade, powered fiber optic transmission system specifically designed for satellite news gathering (SNG) and demanding field production applications using the JVC GY-HM890 camcorder. This system leverages SMPTE hybrid fiber optic technology combined with an AB PowerPlus power supply to deliver a complete signal and power solution over a single, robust cable. It is engineered for scenarios where cameras must operate at extreme distances from the production truck or control point, such as in remote news locations, large-scale sporting events, or disaster zones, requiring uncompromised signal integrity and reliable camera power in challenging environments.

The system transmits HD/3G-SDI video, audio, Genlock, and camera control data via the fiber optic core, ensuring pristine quality and complete immunity to electromagnetic interference over distances that can exceed one kilometer. The integrated AB PowerPlus system provides regulated DC power directly to the camera head through the cable's copper conductors, eliminating the need for local batteries or generators at the camera position—a critical feature for long-duration, unattended operation. The system includes a camera-mounted transmitter, a base-station receiver, and the AB power supply/regulation unit, all designed for interoperability and ruggedness.

By combining long-range fiber optic signal transmission with a professional camera power system, the FS-790SNG offers broadcasters a turnkey solution for deploying the GY-HM890 camera in the most logistically difficult SNG and outside broadcast scenarios. It simplifies cabling, enhances operational reliability, and provides the freedom to position cameras optimally without being constrained by power availability or signal loss, making it an essential tool for global news operations and major event coverage.
