Gain Flattening Filter

Gain flattening filters based on fiber Bragg grating with model number of  OEGFF-100 are now available at O/E LAND INC.   OEGFF-100 can be used in C band or L band erbium doped fiber amplifier (EDFA) or Raman amplifier. Advanced fiber Bragg grating fabrication technology and patented temperature compensation package ensures the best gain equalization performance for your EDFA products.

OEGFF-100 transmission curve is custom designed to match your specific gain curve with a precision of +/- 0.15dB with an attenuation to 5dB from wavelength 1520nm to wavelength 1625nm,   with a precision of  +/- 0.25dB with a maximum attenuation up to 15dB from wavelength 1520nm to wavelength 1625nm.

Quickly turn around time is another feature of our GFF product. We can provide our customer prototype GFF with new designed curve in one week.
