FBG (Fiber Bragg Grating) Array

FBG (Fiber Bragg Grating) Array

Alxenses’s Fiber Bragg Grating (FBG) array is produced using advanced fabrication technique to write many FBGs in a single strand of optical fiber without any splicing points. The mechanical strength of Alxenses’s FBG arrays is therefore significantly better than FBG arrays produced by slicing many FBG arrays produced by slicing many FBGs together. The high quality FBG array with customized wavelength and spacing allow distributed measurement over long distance. FBG arrays are particular suitable for large-scale sensing in strain, temperature or pressure monitoring in oil, gas, civil engineering, aviation and marine industries.

Features:

  • Low insertion loss
  • Spliceless FBG Array
  • Customized FBG array configuration
  • Accurate FBG wavelength and reflectivity

Applications:

  • Large-scale strain and temperature monitoring in oil, gas, civil engineering, aviation and marine industries.
