摘要

光纤衰减是光纤传输性能测试的基本参量。本文通过对光纤衰减测试原理的分析

利用数字锁相技术

通过以计算机为核心

高精度的AD转换、配以DSP技术的数字信号处理

实现了长距离光纤衰减的检测

并通过测试结果比对表明测试系统切实可行。

Abstract

Attenuation is one of the base parameters of optical fiber transmission performance test.In this paper

based on the analysis of the optical attenuation test principle

the attenuation test of long optical fiber was realized by employment of digital phase lock technology and the high precise AD conversion on the base of PC and the DSP digital signal process.Our system was proved feasible by data comparison with PK2200 test system.
