Definition
The 1330nm FBG laser is a fiber Bragg grating (FBG) laser with a specific wavelength. This laser achieves specific wavelength laser output by integrating a fiber Bragg grating and is packaged in a BTF form to provide stable performance. Its working principle is based on the wavelength-selective reflection characteristics of the fiber Bragg grating.
