Fiber Bragg Gratings : Gain Flattening Filters

iXFiber Gain Flattening Filter restores all wavelengths to approximately the same intensity.

The high flexible process allows a fast prototype delivery time. Fiber Bragg Grating technology achieves low systematic errors. Chirped and Slanted (iXTra) FBG are performed on internal specialty fiber to achieve High Return Loss and High Frequency Ripple. Furthermore, iXBlue Photonics GFF can be delivered with Polarization Maintaining Fiber (PMF).

Key features :

  • C & L Band
  • Weak error function
  • Low excess insertion loss
  • Low PDL & PMD
  • Custom design, PM available
  • Telcordia qualified package
  • Flexible process allowing fast prototype delivery time
