一、引言目前,多模光导纤维的基频传输带宽的测量普遍采用国际IEC文件建议的两种方法。一种是扫频法,即对光纤直接进行扫频测量;一种是利用付立叶变换的脉冲法。我们根据后一种方法研制了一种带微计算机的光纤带宽测试系统。
I. INTRODUCTION Currently, the measurement of the fundamental frequency bandwidth of multimode optical fibers generally adopts two methods recommended by international IEC documents. One is the swept frequency method, which directly swept the optical fiber measurements; one is the use of Fourier transform pulse method. We developed a fiber optic bandwidth test system with a microcomputer based on the latter method.
