F-P标准具的特性易受温度影响，温度变化时，其透射峰会发生漂移，将其应用于光纤光栅波长解调时，温度波动会给波长解调精度带来影响。分析了F-P标准具的温度特性对光纤光栅波长解调精度的影响程度，并分别采用温度稳定性为±1．5 G Hz和±3 G Hz的F-P标准具进行了稳定性和重复性实验。实验结果表明：光纤光栅传感器的中心波长不同，由F-P标准具的温度特性产生的解调误差也不同；采用2种F-P标准具测得的稳定性误差最大值分别为0．528 pm和0．676 pm ，重复性误差最大值分别为1．77 pm和2．01 pm。

The characteristics of Fabry-Perot(F-P) etalon can be easily affected by temperature , the transmission peaks of F-P etalon drift with the fluctuation of temperature ,and when F-P etalon is applied in the fiber Bragg grating (FBG) wavelength demodulation ,the fluctuation of temperature may cause wavelength demodulation error .The impact of F-P etalon temperature characteristics on the FBG wavelength demodulation accuracy was analyzed ,and the stability experiment and repeatability experiment were carried out using F-P etalons with thermal stabil-ities of ± 1 .5 GHz and ± 3 GHz respectively .The analysis and experimental results show that the standard deviation of the demodulation error w hich is generated by the temperature charac-teristics of the F-P etalon is different if the center wavelength of the FBG sensor is different ;the maximum stability errors obtained by two F-P etalons are 0 .528 pm and 0 .676 pm ,and the maximum repeatability errors are 1 .77 pm and 2 .01 pm respectively .
