Fiber Optical Transmitter/Receiver 6GHz Analog/Digital

SKU: RFOF

The RF over Fiber (RFOF) system is designed to create a high-performance RF link between two locations using fiber optic cables. It offers strong immunity to electromagnetic interference, wide bandwidth, low signal loss over long distances, minimal distortion, low power consumption, and high reliability, all in a simple, easy-to-deploy format. The system operates by converting an input RF signal into an optical signal using a high-linearity DFB laser transmitter, and then reconverting it back into an RF signal at the receiver end using a high-linearity photodiode integrated with a low-noise amplifier. This transmitter-receiver pair forms a transparent RF fiber link. RFOF units are available in 1310 nm and 1550 nm wavelengths, enabling wavelength-division multiplexing (WDM) for added flexibility. For example, bidirectional RF communication can be achieved over a single fiber using two transceivers at different wavelengths and WDM cable adapters. Additionally, up to three channels can be transmitted through one fiber using three transceivers at different wavelengths with our matching WDM adapters. Modules are available in both rackmount enclosures and ruggedized outdoor aluminum housings, with built-in temperature compensation in the transmitter for improved stability. To form an RF link, a matched pair of transmitter and receiver (same wavelength) is required. For bidirectional communication over a single fiber, two such pairs are used in conjunction with either WDM fiber patch cables (e.g., 1310 nm and 1550 nm) or circulator-based patch cables (same wavelength). We offer plug-and-play 3-port patch cables that connect directly to the transceivers and the main fiber line.
Typical applications include telecommunications, satellite ground stations, radio telescopes, distributed antenna systems, broadcast audio/video transport, and timing synchronization. Use cases include point-to-point RF transmission over distances ranging from meters to many kilometers, remote antenna connectivity for base stations, and satellite antenna extensions to remote facilities.
