摘要
主要介绍单纤单向传输两路模拟基带信号光端机的构成及工作原理 ,对光端机的主要性能进行分析 ,对出现的问题提出改进方法 ,对光发射端所采用频率调制和脉冲频率调制以及光接收端所采用脉冲倍频。
Mainly introduced construction and working principle of optical transceiver which transmits two way analog base band signal by Single fiber along with single direction. The main performance of the transceiver is analysed, and the improving method has been provided for problems in transmission. The outline for frequency modulation and pulse modulation on transmitting end, and pulse double frequency and low pass filter demodulation on receiver end are staded.
