高精度的光纤衰减系数测试系统的设计

Design of highly precise measurement system ofoptical fiber attenuation coefficient

利用常规仪器设备,设计了一套集光、机、电为一体的光纤衰减测量系统,实现了数字化监测显示,并可与微机接口;采用双光路法,消除了由于光源光强不稳定产生的误差。

Using conventional instrument, a measurement system of optical fiber attenuationcoefficient is designed. It realized digital display, and it can easily interface with computer. Usingdouble optical circuit, system errors caused by unstability of light intensity with traditionalinstrument are avoided.
