This paper describes two approaches to measuring transmission losses in optical fibers by the thermal-rise technique. Rapid and convenient loss determinations can be made on short (~10-cm) lengths of fibers. Values of loss as low as ~10(-7) cm(-1) (0.043 dB/km) can be measured with transmitted light power of ~100mW.
本文介绍了两种通过热升技术测量光纤传输损耗的方法。可以对短（约10厘米）长度的光纤进行快速便捷的损耗测定。在约100毫瓦的传输光功率下，能够测量低至约10^(-7)厘米^(-1)（0.043分贝/千米）的损耗值。
