The JVC Professional HD-4300-OGFTX50 is a specialized 3G-SDI transmitter card engineered for the OpenGear platform, a standardized frame system widely used in broadcast infrastructure. This card is designed to reliably distribute high-bandwidth digital video signals from a central source to multiple destinations within a professional facility. Its primary function is to take three independent channels of 3G-SDI video input—each capable of carrying uncompressed HD video, embedded audio, and ancillary data—and amplify or re-clock these signals for robust, long-distance transmission over coaxial cable. This process ensures signal integrity is maintained, preventing degradation that can occur over extended cable runs in routing systems, production trucks, or large venues.

Housed in a single OpenGear card slot, this transmitter module offers a high-density, easily managed solution for signal distribution. It typically features automatic cable equalization to compensate for signal loss and supports a wide range of SD, HD, and 3G-SDI formats for broad compatibility. By providing three dedicated output channels per card, it helps streamline the signal flow from routers, servers, or production switchers to various endpoints like monitors, recorders, or additional processing equipment. Its integration into the OpenGear ecosystem allows for remote monitoring and control via system software, making it a dependable, scalable component for building and maintaining modern broadcast video pathways.
