摘要：

本文利用价格低廉的 1 310 nm商用光纤分束器、铝箔导热等对光纤温度传感器实验装置进行了改进，并测量了改进后传感器的温度系数，发现改进后的温度系数更加稳定，导热条件对温度系数的测量影响较大. 最后对此实验的教学提出了建议.

Abstract:

In this paper，the optical-fiber temperature sensor experiment is modified by using a

cheap commer- cial fiber splitter at 1310 nm and aluminum foil for thermal conducting. The

temperature coefficient is measured and found to be more stable after improvement. Also，the

conducting condition can infect the temperature coefficient a lot. At last，teaching

suggestion is proposed.
