摘　　要：介绍了单模光纤基带频率响应的两种测量方法：一种是由光纤的色散和光源的光谱分布来确定基带频率响应；另一种是直接在频域测量得到基带频率响应。并对这两种方法的测量结果进行了比较。光源限于目前被广泛使用的多级模半导体激光器。In this paper,two methods have been introduced to get the baseband frequency response of single mode fiber. The first method uses the dispersion of fiber and the spectrum distribution of Optical source to determine the baseband response,the second directly measures the baseband response in frequency domain. Optical source is restricted to multilongitudinal-mode diode lasers,which is widely used presently.
