Description
Athermal Packaged FBG is a method of compensating the temperature coefficient of fiber grating with a negative temperature coefficient packaging sleeve. It uses a material that does not have a negative temperature coefficient. The encapsulation sleeve can just fully compensate the wavelength drift caused by the temperature change of the FBG. The encapsulation results in a good temperature characteristic, in the environment of -10℃ to 60℃, the temperature coefficient of the fiber grating can reach 1pm/℃, and has good long-term temperature characteristic.
