Super-high-speed all-optical communication system

Abstract

A super-high-speed all-optical communication system inclues a signal frequency acquisition circuit, a detection comparison circuit and a frequency modulation output circuit. The signal frequency acquisition circuit collects the signal of the input end of the signal transmission channel of the control end of the ultra-high-speed all-optical communication system, A pi-type filter circuit composed ofan inductor L1, a capacitor C2 and a capacitor C3 is used for filtering, and the detection comparison circuit uses an average detection circuit pair composed of an operational amplifier AR1, an operational amplifier AR2 and a diode D1 to lock the signal in an average range, and simultaneously uses an operational amplifier AR3, an operational amplifier AR4 and a resistor R10 A hysteresis comparison circuit composed of a resistor R13 filters out clutter on the signal, At last, that frequency modulation output circuit use the frequency modulation circuit composed of the transistor Q3, the transistor Q4 and the capacitor C6 to output the frequency modulation signal, so as to prevent the frequency hopping and distortion of the signal. The output signal voltage of the operational amplifier AR4is regulated by the feedback of the transistors Q1 and Q2.
