1555.02 nm Athermal Package FBG, 20 GHz FWHM Planar Lightwave Circuit (PLC) and uses the temperature sensitiveFBG is the key component that acts as a rejection filter in telecommunications. The center wavelength of FBG is very sensitive to changes of temperature or strain. The package is used by the technology of temperature compensation to make the wavelength very stable.
