摘要
按照光纤通信系统的原理,对光发射机的主要组成部分电源、调频电路及锁相环在原理和实现电路上进行设计。使信号源发出的信号经过光发射机后信号失真小,信噪比高,满足信号传输高质量的要求。
On the theory of optical fiber communication system, the main parts of optical transmitter which are power supply. frequency modulation circuit and phase-locked loop was designed in theory and realization circuit. After passing through the optical transmitter, the signal which come from signal source could fulfill the requirements of high quality of signal transmission with a smaller distortion and a higher Signal-to-Noise in the new design.
