Several materials with large coefficient of expansion were selected to make packaging components , and it was found that the packaging materials have good temperature sensitivity and compatibility with optical fibers . experimental accuracy and repetition of fbg temperature sensitivity and compensation were discussed . have selected several materials which has bigger coefficient of expansion to do packaging components , have made many temperature experiments , there have not flaws , such as aging , crackle , absciss layer , packaging materials have good temperature sensitivity and compatibility with optical fiber ; have designed the simple and practical packaging components , have performed a serials of experiments about accuracy and repetition of fbg wave - length , have obtained the first step conclusion ; have analyzed the result and made comparison between the result of different experiment , have summarized the best packaging effect and several rules to reduce mistskes
