The JVC Professional FS-790PSAG is a comprehensive powered fiber optic transmission system designed for professional broadcast applications with the JVC GY-HM890 camcorder. This system integrates SMPTE 304M-compliant hybrid fiber optic technology with an AB Power Wafer power supply to create a complete, single-cable solution for transmitting video, audio, data, and power over long distances. It is engineered for studio and outside broadcast environments where cameras are positioned far from the control room, such as in large venues, stadiums, or expansive studio complexes, requiring pristine signal quality and reliable, continuous camera operation without the limitations of traditional copper cabling.

The system transmits HD/3G-SDI video, audio, Genlock, and camera control signals via the fiber optic core, ensuring complete immunity to electromagnetic interference (EMI) and ground loops over runs of several hundred meters. The integrated AB Power Wafer system delivers regulated, clean DC power directly to the camera head through the cable's copper conductors, eliminating the need for a separate power cable or on-camera battery. This is critical for permanent installations or long-duration broadcasts where uninterrupted power is essential. The system comprises a camera-mounted transmitter, a base-station receiver, and the AB power regulation module, all designed for rugged, reliable performance.

By providing a streamlined, all-in-one cable link for both signal and power, the FS-790PSAG system dramatically simplifies setup, enhances reliability, and maximizes operational flexibility. It allows broadcasters to deploy the GY-HM890 camera at optimal positions without compromising on signal integrity or power availability, making it a professional-grade solution for the most demanding fixed-installation and outside broadcast scenarios.
