Chirped FBG
Description
The Chirped Fiber Bragg Grating (FBG) is a precision-engineered optical component designed for advanced fiber optic applications requiring dispersion management and wavelength-selective reflection. Unlike uniform FBGs, chirped FBGs feature a variable grating period along their length, enabling different Bragg wavelengths to reflect at distinct positions within the grating. This property introduces controlled optical path differences that make the Chirped FBG ideal for compensating dispersion in long-distance fiber optic networks.
With a wide reflection bandwidth, low insertion loss, and high reflectivity, the Chirped FBG is widely used in applications such as EDFA gain flattening, ASE noise suppression, and band rejection filtering for WDM systems. Supported center wavelengths range from 1064 nm to 1650 nm, with customizable options for fiber type, recoating material, and connector interfaces.
Whether integrated into high-speed communication links or precision sensing systems, this FBG delivers high performance and reliability, ensuring stable optical characteristics even in demanding environments. Designed to meet industry needs, it is available with SMF-28 compatible fibers and customizable pigtail lengths.
