GFF

GFF or gain-flattening filters are optical devices which ensure that all
wavelengths are restored to the same intensity.

They are often used with Erbium-doped fiber amplifiers also known as EDFA.
These filters have an operating wavelength spectrum of 1530 to 1565 nm.



Features:

Low Insertion Loss
Flat Spectral Gain
High Stability and reliability

Applications:
EDFA
