FBG Array is a new type of optical passive component. We inscribe multiple FBGs on the same fiber, that is, FBG array, which is suitable for long-distance and multi-point simultaneous testing. FBG array can improve the stability and reliability of the system, widely used in fiber optic sensing systems. The sensor packaged by the FBG array is smaller in size and has more measurement points, is widely used in the measurement of electric power and aviation.
