光纤通信中的光源

光源器材是光纤通信设备的中心，它的作用时间电信号转换成光信号。光纤通信中常用的光元器材有半导体激光二极管（LD，或称半导体激光器）和半导体发光二极管（LED）两种

(The light source equipment is the center of optical fiber communication equipment, and its function is to convert electrical signals into optical signals. Optical components commonly used in optical fiber communication include semiconductor laser diodes (LD, or semiconductor lasers) and semiconductor light emitting diodes (LEDs).)
