Gain Flattening Filter With 980nm Blocking
Iridian Spectral Technologies
Gain Flattening Filters (GFF’s), also known as gain equalizing filters, are used to flatten or smooth out unequal signal intensities over a number of specified channels in the C-, L- and U-Bands. This unequal signal intensity usually occurs after an amplification stage (e.g., EDFA and/or Raman). GFFs are used in conjunction ...
