本设计是一光纤发送系统,该系统主要有光发送机,光接收机,光纤网络等组成。模拟信号经发射光端机转换成数字信号后,将电信号转换成光信号,通过光纤网络到光接收机,其把接收到的光信号转换成电信号,最后将数字信号转换成模拟音频信号。信号传输是通过光端机的双机通信来实现的。
The design is a fiber optic transmission system, the system mainly optical transmitter, optical receiver, optical network and other components. After the analog signal is converted into a digital signal by the transmitting optical transceiver, the electrical signal is converted into an optical signal, which is transmitted to an optical receiver through an optical fiber network. The optical signal is converted into an electrical signal and finally the digital signal is converted into an analog audio signal. Signal transmission is achieved through the two-terminal optical transceiver.
