RF Microwave Fiber Optic Delay Line 0.5GHz~18GHz
An RF/microwave optical delay line, as the name implies, is a device that utilizes optical principles to achieve microwave signal delay. It converts the input radio frequency (RF) signal into an optical signal, transmits it a certain distance through an optical fiber or other optical medium, and then converts it back into an RF signal, thereby achieving a time delay of the signal. This process not only preserves the integrity of the signal spectrum, but also precisely controls the length of the delay time through the physical length of the optical fiber.
