光纤衰减测试系统的研究
A Bifrequency System Used for Detecting Optical Fiber Loss
-
摘要: 在光纤通信中,光纤衰减是光纤质量的一项重要指标,通常需要测试光纤在某一较宽频段内各个波长的光纤衰减值,以选择合适的光源工作波长.笔者设计了一种新颖的双频检测光电系统,并采用单片机进行数据采集和处理.Abstract: Optical-fiber loss is an important index of optical-fiber quality in commuication.Under noraml conditions,We need to determine the optical-loss value of each wave length in a wide spertrum for selecting the most suitable wavelength of light source.A bifrequency photoelectronic system is proposed in this paper,in which an 8-bit microcontroller is used for collecting and processing data.
