负温度补偿封装光纤光栅（50GHz滤波器） 特价：负温度补偿封装光纤光栅（50GHz滤波器）

负温度补偿封装光纤光栅（50GHz滤波器）Athermal Package FBG（50GHz滤波器）

光纤光栅的ZX波长对温度和应变敏感。特殊的封装可以YZ波长对外界敏感的特性。基于一种特殊的负温度补偿材料，太辰光通信能将波长的漂移降到Z低。

The wavelength of FBG is sensitive to changes of temperature or strain. A special package is needed to restrain the characteristics. Based on negative expansion coefficient material, T&S can decrease the wavelength shift to a minimum.
