For the all optical fiber current sensor, how to carry on the temperature compensation has been the difficulty and focus of research at home and abroad, and it is also the only way to make these sensors to the utility. Examples and data are first used to show the temperature effect on the performance of all fiber current sensor. Then, based on analyzing all fiber optical current sensor principle and structure, the mechanism of each factor which is affected by temperature is illustrated and the latest progress is given. Finally, the effects and the practical advantages and disadvantages of each method are analyzed. Ultimately, it can be drawn: by using a single method to control factors on the performance of all-optical current sensor is not ideal, but through the control of multiple factors and carrying on data processing in the final output are better ways to achieve better temperature compensation effect, so that the output of the entire fiber-optic current sensor is more accurate and more stable.
