The JVC Professional FS-790SNVG is a high-performance, V-Mount powered fiber optic transmission system engineered to integrate seamlessly with the GY-HM890 camera, creating a robust solution for live broadcast and remote production. This system utilizes SMPTE 311M single-mode fiber cable to transport multiple high-definition video and audio signals, intercom, data, and power over exceptionally long distances with no signal degradation, making it ideal for stadiums, large venues, and outside broadcast (OB) trucks. By adopting the standardized SMPTE hybrid fiber interface, it ensures compatibility within a broader broadcast ecosystem, allowing for cable runs of hundreds of meters between the camera and the base station unit. The V-Mount "PowerPlus" designation indicates it incorporates a dedicated battery plate, providing reliable and continuous DC power to the attached camera head, eliminating the need for a separate local camera battery and simplifying cable management on complex rigs.

This system dramatically increases production flexibility and camera placement options by freeing operators from the traditional constraints of copper cabling. The FS-790SNVG consists of two core components: a compact Camera Adapter (CA) that attaches directly to the JVC GY-HM890, and a corresponding Base Station (BS) that interfaces with the broadcast production switcher or control room. The fiber connection carries a bidirectional data stream, enabling not only the transmission of pristine video and audio back to the control room but also the simultaneous return of critical signals to the camera, such as program video, intercom, tally, and camera control data. This creates a fully functional, studio-style camera system with all the advantages of a remote fiber-optic link, supporting the highest quality productions.
