　　According to the sensing principle of FBG,the measurement performance of magnetic field sensor based on the differential group delay (DGD) in FBG isdiscussed in this article.The measuring linearity and dynamic range are simulated through the simulation software respectively,and it is shown that the lin-ear relationship between the magnetic induction intensity and DGD is only applicable to small magnetic field.
