1-18GHz Analog Link RF Over Fiber Operating Instructions
The 1-18GHz Analog Link RF Over Fiber consists of an electro-optical conversion module, optical fiber, and electro-optical conversion module. Used to modulate microwave signals and transmit them in the form of light through optical fibers, it can effectively improve anti-interference ability, without affecting the field distribution with electromagnetic radiation, and avoid the use of long microwave cables. Simulate RF fiber optic link frequency band coverage from 1GHz to 18GHz.
