1552.52nm DWDM Fiber Bragg Grating Filter

1552.52 nm DWDM fiber grating filters can be divided into uniform fiber Bragg grating (FBG), chirped fiber grating, tilted fiber grating, and long-period fiber grating types according to their grating structures. They can be classified into bandpass, bandstop (notch), and reflection types according to their filtering functions, and fixed wavelength and tunable types according to their tuning methods.
