为了研究单模光纤宏弯损耗特性与温度变化的关系,文章根据Faustini L提出的理论公式进行了热光效应和热膨胀效应修正,基于该公式对温度影响下的纤芯—包层—无限涂覆层结构SMF28和1060XP单模光纤宏弯损耗分别进行了仿真分析,探究了温度、波长和弯曲半径等因素对单模光纤宏弯损耗特性的影响,并得到两种单模光纤与温度之间的线性拟合结果。研究结果表明,宏弯损耗随弯曲半径的减小而增大,随波长的增大而增大,随温度的升高而减小;当弯曲半径和波长一定时,宏弯损耗与温度之间具有单调性;增大弯曲圈数可有效增加其对温度的灵敏度。
In order to study the relationship between the macro-bending loss characteristics of the single-mode fiber and the temperature change
the thermo-optical effect and thermal expansion effect are corrected according to the theoretical formula proposed by Faustini L. Based on this formula
the macro-bending loss of SMF28 and 1060XP single-mode fiber with core-cladding-infinite coating structure under the influence of temperature is simulated and analyzed. The influence of temperature
wavelength
bending radius and other factors on the macro-bending loss of SMF28 single-mode fiber is explored
and the linear fitting results between the temperature and the two kinds of single-mode fibers are obtained. The results show that the macrobending loss increases with the decrease of bending radius
and the increase of wavelength. The loss also decreases with the increase of temperature. Under certain bending radius and wavelength
the macro-bending loss and temperature are in monotonic relationship
which means increasing the number of bending turns can effectively increase the sensitivity to temperature.
