Athermal Packaged FBG

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 -5℃ to 70℃, the temperature coefficient of the fiber grating can reach 1pm/℃, and has good long-term temperature characteristic.

Features of Athermal Packaged FBG

  • 100G/50G Channel Spacing

  • Low Insertion Loss

  • Excellent Channel Isolation

Application of Athermal Packaged FBG

  • Regional and Long Haul

  • Dwdm Networks

  • Wavelength Reference
