摘　　要：介绍了一种设计制作磨抛型单模光纤密集波分复用(DWDM)器的方法。依据磨抛型单模光纤功率耦合器的基本原理,导出设计这类耦合器的相关参数方程及绘出它们的关系曲线。对用小芯径单模光纤制作1.55μm和1.31μm光波长DWDM耦合器的技术参数作了具体计算和讨论。设计的DWDM耦合器能方便与掺饵光纤放大器(EDFA)等级联形成组件在光纤通信链路中使用。A designing method for making DWDM coupler is introduced, which is based on the polished power coupler of single-mode fiber.According as the basic theory of polished power coupler of single-mode fiber, the equation and relation curve of the parameter of this coupler is educed. Detailed calculation has been done by using the technical parameters of 1.55μm and 1.31μm optical wavelength in DWDM coupler which is made of small radius fiber.The coupler designed by using this method can combined easily with EDFA, which can be used in the fiber communication link.
