Buying Gain Equalization Filters
Gain equalization filters are used to make the gain spectrum of an optical amplifier device flatter over a certain optical frequency range. These filters are essential for maintaining uniform signal amplification across multiple wavelengths in wavelength division multiplexing (WDM) telecom systems, ensuring consistent performance and signal integrity.

 7639 Cordner Lasalle, Quebec H8N 2X2 Canada |  The Gain flattening filter (GFF), based on fiber Bragg grating technology, with model number OEGFF-100 is a reflective type filter. The OEGFF-100 can be used in C-band or L-band erbium doped fiber amplifier (EDFA) or Raman amplifier. One advantage of the OEGFF-100 compared with the thin film based GFF filter is that each filter shape is different due to customized fitting curve, and therefore no accumulated error when several of them are cascaded with each other. Advanced fiber Bragg grating fabrication technology and a patented temperature compensation package ensures the lowest ripple and smallest error function for the best gain equalization performance for your EDFA products. |
