从光纤温度传感器出发，并在我们长期实验的基础上，分析了大多数光纤传感器难以走向实用化的原因，并提出了一定的处理方法和建议。我们认为，光纤传感器在推广应用上受到制约的重要原因是其长期稳定性和可靠性存在着问题，影响稳定性和可靠性的两个主要因素是光源输出光功率的漂移和光纤保护层的老化，尤其是位于待测区域的探头、敏感光纤和接续光纤的保护层老化问题限制了光纤传感器的应用
Based on our long-term experiments, we analyzed the reasons why most optical fiber sensors are hard to be put into practical use. Some methods and suggestions are put forward. In our opinion, the main reason that the optical fiber sensor is restricted in its application is its long-term stability and reliability. The two main factors affecting the stability and reliability are the drift of the output optical power of the light source and the aging of the optical fiber protective layer , Especially in the test area of the probe, sensitive optical fiber and optical fiber protection layer aging problems limit the application of optical fiber sensors
