1550.92 nm Athermal Package FBG Laser Source It uses a material thatAthermal 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 5 to 70, the temperature
