FPV Optical Fiber Image Data Modules provide long-distance, anti-interference video and control links for drones and robots when RF is noisy or restricted. This collection covers single-mode optical links with transparent transmission (2. BUS/UART and relay extender. This device include a sky end (TX) and a ground end (RX), Developed for drone signal transmission system with 1/2 Analog or HD video and 1/2 TTL level signal over an optical fiber cable for long distance transmission. Widely used in various. Fiber optic image and digital module adopts fiber optic as the transmission medium, fast transmission speed, strong stability, can meet the demand for large data transmission, not subject to the influence of electromagnetic interference, to prevent eavesdropping, can support up to 50km wired signal. Optical fiber diagram module uses optical fiber as the transmission medium, the transmission speed is fast, the stability is strong, can meet the needs of big data transmission, is not affected by electromagnetic interference, prevent eavesdropping and eavesdropping, can support up to 30km of wired. The fiber optic image data module relay extender module is a real turning point for anyone who needs reliable signal transmission over long distances. It supports wired signals over distances of up to 30 km and is an indispensable component for FPV systems where clear and uninterrupted image data. This product is a drones accessories Data Transmission System designed for FPV drones and robots.
