本研究研究了温度和弯曲半径对SH-4001、MH-4001和GH-4001聚合物光纤（POFs）在25至80°C温度范围内变形的功率损耗和平均塑性能量密度（ped）的影响。结果表明，该方法为预测三种POFs的功率损耗提供了一种可行的方法。根据实验数据，导出了给定变形和温度条件下三种POFs的功率损耗曲线拟合方程。估计结果与实验结果的差异小于6%。实验结果还表明，在本研究考虑的三种POFs中，GH-4001纤维具有较高的玻璃化转变温度，并且具有最佳的抗功耗，特别是在高温变形条件下。
This study investigates the effects of temperature and the bend radius on the power loss and average plastic energy density (APED) in SH-4001, MH-4001 and GH-4001 polymer optical fibers (POFs) deformed at temperatures ranging from 25 to 80°C. The results show that the APED index provides a viable means of predicting the power loss in the three POFs. Based on the experimental data, curve-fitted equations are derived to estimate the power losses in the three POFs under given deformation and temperature conditions. The difference between the estimated results and the experimental results is found to be less than 6%. The experimental results also indicate that, of the three POFs considered in the present study, the GH-4001 fiber has a higher glass transition temperature and has the best power loss resistance, particularly under higher temperature deformation conditions.
