一、概述光通信系统一般来说,由光源(发光器件)调制器、光缆、检测器(光接收器)及有关耦合器和连接器组成。其中主要由光导纤维组成的光缆,在传输系统中作为光波导,它较金属线传输系统具有独特的频带宽、容量大、损耗小和不受外界干扰等优点。光纤主要是用玻璃拉丝成纤维,它包括纤芯和
I. Overview Optical communication system in general, from the light source (light-emitting device) modulator, cable, detector (optical receiver) and the coupler and connector. The optical fiber cable, which is mainly composed of optical fibers, has the advantages of unique frequency bandwidth, large capacity, small loss and no external interference as the optical waveguide in the transmission system. Optical fiber is mainly drawn with glass fiber, which includes the core and
