简易数字光纤通信系统的误码测试与分析

IInvestigation on Error Code of Facility Digital Optical Fiber Communication System

应用误码测试仪、光功率计等对简易数字光纤通信系统实验箱进行误码测试．分析结果得到:误码率随数字信号密度的增加而增大;在实验参数范围内,误码率随光源输出光功率以及光接收系统增益的增大而减小．实验表明此法简单有效,且能准确判断误码的原因和位置,可为实际数字光纤通信网络的误码测试和分析提供方法上的指导．

This paper inquires into the measurement and analysis of error code ratio for a facility digital optical fiber communication system. The results indicate that the error code ratio increases with enhancing the digital information density while it decreases with enhancing the optical power and the gain of optical reception cell in the range of processing parameters. The method is exhibited as a simple but effective one for estimating the origin and position of the error code.
