Name: Apodized FBG
Brand: AtGrating Technologies.

Apodized FBG

Apodized FBG is a wavelength-reflecting optical device produced by ultraviolet light and phase mask inscription on the optical fiber. It is a basic optical fiber sensing element and is widely used in the fields of optical communication and sensing. AtGrating adopts advanced production technology and Apodized technology to mass produce FBG of various wavelengths in the C+L band, with precise center wavelength, stable performance, high reflectivity, and small 3dB bandwidth.
