Thin Film Gain Flattening Filter

Thin Film Gain Flattening Filter

Gain flattening filters (GFFs) flatten the gain profile in optical amplifiers by selectively removing excess power.

The Lumentum thin film GFF offers an excellent match to the target loss profile with low excess loss and error function, even for exceptionally deep (>20 dB) and steep  GFF (>2.5 dB/nm) profiles.

Customized thin film GFFs are available in the C, L, and S bands. All Lumentum thin film GFFs fulfill Telcordia GR-1221 requirements.
