    • Non-thermal (thermally insensitive) packaged Fiber Bragg Grating (FBG)

    Fiber Bragg Gratings (FBG) are highly sensitive to temperature changes. Their thermal sensitivity is approximately 6.7 ppm/°K (at a wavelength of 1550 nm, it is +0.11 pm/°K). Non-thermal encapsulated FBGs are designed to passively compensate for the thermal sensitivity of FBGs through the expansion matching of the shell elements and the wavelength shift of the FBG under temperature influence. This design allows customers to achieve all the advantages of Fiber Bragg Gratings while maintaining high wavelength stability over a wide temperature range

    Product features：Wavelength ultra stable; Excellent optical performance; Compact and sturdy packaging; Flexible customization

    Part Number：MP-GTL-FBG-AP-850

    Application area：Dense Wavelength Division Multiplexing (DWDM) fiber optic communication system | High precision fiber optic sensing | Stable laser light source
