The principle of fiber optic delay line

Figure 1 showsFiber optic delay lineUnit schematic diagram. The RF electrical signal is input into a laser diode (LD), which converts the input RF electrical signal into a modulated optical signal, which is coupled into an optical fiber through an optical connector. The photodetector (PD) converts the RF modulated optical signal back into the original RF electrical signal. The frequency spectrum of the output RF electrical signal * is the same as that of the input RF electrical signal, but it is delayed for a period of time using optical fiber as a medium, which means that the RF signal is stored instantaneously inFiber optic delay lineIn a unit, the length of storage time is directly proportional to the length of the optical fiber, which isFiber optic delay lineThe principle.
